Primary terms tend to be 1 or 2 words, often Nouns or Verbs. These may be ambiguous, and have “mixed SERPs”. Includes many Navigational/Brand queries, and may also cover certain Entity Informational queries
Example: Shoes, Pizza, Running, Twitter, etc.
What are Mid Terms?
Primary with Secondary terms tend to be 2 to 5 words, Nouns/Verbs with Prepositions or Nouns/Verbs with Adjectives/Adverbs. Often more Informational and/or Commercial queries, with less ambiguity (fewer mixed SERPs).
Example: Shoe shops near me, Best LED TV, etc.
What are Long Tail Terms?
Primary, Secondary and Tertiary terms tend to be 4+ words, Nouns & Verbs, Prepositions & Adjectives/Adverbs (even full sentences). Many Informational and some Commercial intent queries are of this type.
Example: Why are Oxford shoes called Oxfords?
Tips & Tricks - Which Keyword To Target?
The longer the term you target, the more distinctive, specific, and unambiguous it is, the fewer pages you should need to produce to be relevant for it, and fewer internal/inbound links.20
The shorter, less detailed the term you want to rank for, the more pages you will need, with more internal links and inbound links pointing to it. (Head/Hub pages)
Each page is meant to target the main term, or set of terms (see "group") If you produce “topic expanding” content, you will naturally have pages that include the same “root” term. (Not really cannibalizing!)
Each page is meant to target a specific thing. This can be by Variant, Target, or Intent. Variants differentiate by features. Targets differentiate by audience attributes. Intents by nature/purpose.
Understanding the Keywords SERP Nature With Example
Consider the following queries:
* get ink out
* get pen ink out
* how to get pen ink out
* how to get pen ink out of the shirt
* how to get red pen ink out of a shirt Are the SERPs different for each?
As you can see, the number of words may change - the nature and topic do not. The order of results may shuffle, but the majority of results are on the same page.
Note the SERP changes, which version triggers ads and where and the Featured Snippets.
Also, notice that we didn’t really need “how-to” in the query? can imply it by removing it - quite safely, as there’s very little chance for ambiguity. (There isn’t a lot of content about “why to remove ink” etc. :D) Shows how/why researching competition is important!
What are Ambiguous Queries?
Ambiguous Queries may mean mixed-intent SERPs (so you may see Commercial and Informational etc.) Targeting longer queries may mean lower volumes, but also means less competition, including advertisers!
Example
Query: women's eco-friendly red clutch handbag London
https://google.com/search?q=womens+eco+friendly+red+clutch+handbag+london…
Keyword: handbag
Keyword phrase: clutch handbag
Target terms: Women(s) and London
Variants: eco friendly and red
Intent: Implied (product, so it’s primarily commercial)
[Women's eco-friendly red clutch handbag london]
This could be shifted from implied-commercial, towards informational (com+info), by including “which” or “best” Or the results could be refined by adding Season, Brand, Material, Size, differentiators (sequins?), etc.
Next up is Keyword "nature" (classification)
We know that Google classifies queries. We don’t know if that includes types/specifics of Intent, but we do know it covers Adult and YMYL! Certain words/phrases will trigger different behavior (poss. inc. anti-spam Algo. )
Then we have Keywords “groups”
Some words have abbreviations and/or variant spellings etc. There are also synonyms, similar terms, and descriptors. So any “keyword” may actually cover a range of variant phrases. (And a page may show several "phrases", and their variants!)
[women's eco-friendly red clutch handbag london]
eco friendly ?= sustainable | recycled | green
red ?= ‘’ | scarlet | burgundy | strawberry
There’s more to keywords! Keywords are a bridge -between the User and the Search Engine!
You need to understand Nature, Intent, Parts of Speech, and how they pertain to the Journey Stage, SERP Features, etc. You need to see ways to utilize that information in your content.
What are the things needed to do Keyword Research?
Change your research, the docs, and the reports you make.
Do NOT just include Term, Volume & CPC!
Include:
Primary term(s)
Term group
The intent of each term
Intent triggers (or if implied)
Journey stage
Synonymous words/phrases
Terms that make a difference (or not)
Conclusion:
You will find SEO life gets much (much!) easier when you capture/attach the additional information. From prioritizing targets through to ideation, identifying internal link targets, etc. So, give it a go. Go Beyond “Keywords”.

To become a PHP programmer, you need to have PHP programming skills, as well as a college degree. Bear in mind, this degree isn’t mandatory; sometimes, verifiable work experience in the field will be taken into consideration instead. To become a PHP programmer, the most basic thing needed is experience. All you have to do is download the scripting language and configure the server for it to work.
In this context, we will talk in more detail about what PHP is so that you learn everything you need to know about the subject.
What Is PHP And How Does It Work?
PHP is an open-source programming language created for web development. With it we can write small scripts in a procedural way, use object orientation, or even both. This Reference Guide aims to accompany your first steps in this technology. Among the factors that made PHP so popular is the fact that it is open source. This means that anyone can make changes to its structure. In practice, this represents two important things:
- It is open-source, there are no usage restrictions linked to rights. The user can use PHP to program any project and commercialize it without problems is constantly being refined, thanks to a proactive and committed developer community.
- As an easy-to-learn language with tutorials, PHP is ideal for programmers who are just starting out in web development. If this is your case, it is natural to have little familiarity with concepts such as backend, web server, request, and many others. But don't worry, these fundamental concepts are covered in this post. PHP (Hypertext Preprocessor ) is an open-source programming language used for creating dynamic websites. One of its main characteristics is that it is free.
Also, its main use is for website development. However, it has other functions such as support for databases such as MySQL, Oracle, and InterBase, integrating external libraries, and more.
Things You Can Do To Become A Better PHP Developer
There are many different paths to becoming a web developer, and your own experience will present unique challenges. Read on and you'll learn a thing or two if you just take your first steps into this great web development language.
-
Using PHP Core Functions and Classes
If you're trying to do something that seems fairly common, chances are there is already a PHP function or class that you can take advantage of.
-
Create a Configuration file
Instead of having your database connection settings scattered all over the place, why not just create a master file containing its settings and then include it in your PHP scripts?
-
Always Disinfect the data that will go into your database
SQL injections are more common than you might think, and unless you want a big headache later, sanitizing your database entries is the only way to fix the problem.
-
Leave Error reporting enabled at the development stage
Watching the PHP white screen of death is never helpful except to know that something is seriously wrong. When building your app, leave error_reporting and display_errors enabled to see runtime errors which will help you quickly identify where the errors are coming from.
-
Keep favorite snippets close at hand
You'll be coding a lot of the same things throughout your PHP development career, and keeping snippets always available will help save you a lot of time.
-
Use a Good Source editor to save time
Your editor is where you'll spend the majority of your time, so you want to use something that helps you save time.
-
Use a PHP framework
Accept that using a web application development/rapid application development framework would help.
-
Connect with other PHP developers
You don't know everything. And even if you think you do, there are thousands of others who know how to do something better than you do.
What Skills Are Required To Become A PHP Developer?
The job of a PHP Developer requires many technical skills and must continue to be trained throughout his career to cope with changes.
- Essential skills: PHP, Javascript, Symfony, HTML, CSS, MySQL
- Additional skills: Object Programming, Zend, JQuery, Drupal
- Good knowledge of database architecture
- Mastery of the SCRUM methodology is a plus
- It is also essential to self-train to stay abreast of technological developments.
What Training And How To Become A PHP Developer?
The training required to become a PHP developer varies according to the profile, most generally these are studies in an engineering or computer school. Some PHP developers are self-taught, and it is possible to break into the profession without having completed specialized studies. On the other hand, it is quite rare and it requires a great deal of experience and good references.
The Pros and Cons Of Being A PHP Developer?
If you’ve decided to become a PHP developer (or have wisely decided to upskill), then bear in mind the advantages and disadvantages of being a PHP developer.
The pros of being a PHP developer
- You make a lot of money. This is generally true in engineering trades. There are other professions, which we think are very honorable, but the people who work there are paid so little.
- The job is perfect for those who love computers. It may seem obvious, but it needs to be stated. It's a profession that pays well, and yet most software engineers won't have to deal with customers directly.
- You can work freelance. Any software engineer can do it, but good programmers can choose to freelance, they work from home, work on projects posted on the Internet, and get paid.
The Disadvantages Of Being A PHP Developer
As promised, we will also talk about the cons. These points, however, can be said about many jobs. It is after some time of working in the field that you start to see these things:
- It is difficult to change jobs. There is a lot of competition. Right after college, we had several interviews and different types of offers. Now, if someone is looking for a job, he is supposed to have more experience and knowledge in certain technologies.
- Many jobs require knowledge of very specific technologies, such as programming languages, operating systems, hardware, and databases, among others. Not everyone can have all of these specific skills. By looking at the classifieds you will understand what we are suggesting.
- There is too much to know in too little time. This is related to the point above. Technology moves so fast that if you don't update you become irrelevant and can be replaced by the younger ones. It is important to read magazines that talk about the evolution of computer technology.
- You may be required to work overtime. It can be good or bad. However, you may be called upon to work overtime, and without pay, especially when a project delivery date is approaching too quickly.
Overall, however, we would say that the pros of being a software engineer outweigh the cons. People are always happy to work in the field.
What Are The Advantages Of Using PHP?
PHP brings a series of benefits that are easily identified when we analyze its characteristics and the different application possibilities of that language. Today, the programming market is looking for professionals with experience in web applications and, in this scenario, PHP is the main resource. Next, we will tell you the main advantages that show why PHP is a widely used language, especially in web projects.
Intuitive Learning Made Easy
The PHP language is considered one of the easiest to learn among the many options that a programmer can and should have in his portfolio of resources and knowledge. Due to this very large and committed community, in addition to the materials, it is also very easy to request help for some specific points during this learning period.
Open Source
As it is an open-source language, PHP does not incur costs for programmers who want to work with it, which is a great advantage, especially for those who work independently. This represents opportunities to develop general applications for the web, without any legal problems with the founders of the language.
Programmers can also use the open-source facilitator to further improve PHP, eliminating any kind of glitches, bugs, or even working on performance optimization. This is a very common practice in the PHP community, which is proactive in sharing updates so that everyone can use the enhanced versions.
Supports a Large Amount Of Data
One of the main concerns of programmers is the complexity that their web applications will have, since the more resources they have, the more data they will begin to manage. Sites with a variety of visual details, e-commerce stores, and other large web projects tend to need a large amount of information when they are active.
Without PHP, it would be difficult to run these applications with the minimum performance required for the browsing experience. It is not difficult to understand PHP's choice of professionals to develop most of its web projects, since, in addition to the ease of work, there are also direct performance advantages.
Compatibility With The Main Databases
It is important that websites also have a good level of compatibility with databases, as they are a fundamental part of the structure. More than that, it is crucial to get the dynamism to load elements of the pages with agility and without failures. The PHP language makes everything simpler, because it solves these two points well, without restricting the performance of the application.
Among the main databases used, PHP is compatible with:
- Oracle;
- MySQL;
- Interbase;
- SQLite;
- Sybase.
Here is a list of everything you can do with PHP, as well as its additional advantages and disadvantages.
Advantages of PHP
- Free language, which can be easily edited by any developer or programmer.
- Has a very clean syntax, so the learning curve is slower than other programming languages.
- It allows you to easily create work environments.
- Also, It has a very simple installation.
- Integrated in a very simple way into the database.
- There is a large community, which is very active and allows it to be constantly evolving and adapting to the news.
- One of the most widely used programming language worldwide.
- PHP is a cross-platform language, therefore it can be used in various applications and professional environments.
- The code runs on the server-side, and in the browser, it runs in HTML.
- Currently, it can be used in a large number of databases such as: Oracle, MySQL, Interbase, SQLite, Sybase, PostgreSQL, SQL Server, among others.
- They offers security against computer attacks carried out by hackers.
- It has multiple extensions, so it is one of the languages used in projects with high difficulty.
- Supports a large amount of data.
Disadvantages
- In-depth knowledge is required to configure security breaches.
- We Cannot hide the code easily. For its execution, a server is necessary.
- As you have seen, the PHP language is a very powerful, versatile language, and therefore its use has been growing more and more. It is a programming language on the server-side, which allows you to carry out an infinite number of projects.
What We Use PHP?
It is not very difficult to understand what PHP is, but it becomes simpler to know its usefulness and operation when we use concrete examples of applications. Basically, as we said, its use is for the web, thanks to its ability to connect the server and the user interface, taking all the HTML code.
Today, many global websites are using PHP as the basis of their applications. Find out in what situations this programming language is used and understand why.
Website applications
One of the main characteristics of PHP is that it is a much more dynamic language than most of the other options out there. Therefore, it is essential to develop sites that have more complex applications and, for that, we need two things: agility in response time and connection to a large database. For example, none other than Facebook uses PHP!
In practice, the idea of using this language is to decrease the loading time of the pages, allowing the server to work more smoothly to load plugins and applications on websites. In this way, it is possible to agilely develop sites with high performance, even if they are full of resources, and with the guarantee of long-term performance sustainability using the PHP language.
WordPress is another great company that bases all its application programming on the PHP language. This helps us understand why WordPress is the top choice for website development. In addition, PHP also applies to a fundamental part of that platform: its additional plugins!
Like the language of websites, plugins must also have dynamic and agile communication with the server, which is why PHP is the ideal option in this case.
E-commerce
E-commerce has a great need, which is frequent communication with complex databases and full of important data elements. After all, there are many images, videos, and other media related to the products being sold. Therefore, every time you need to load pages, you have to connect to these databases, which could make them cumbersome.
Given this, PHP becomes a great alternative to escape the possibility of having a store that does not provide a satisfactory browsing experience to the user. Due to this, the large online store development platforms already use PHP as the main language to program their back-end.

Conclusion:
Do you want to train as a programmer? We reached the end and found that the PHP language is not such a difficult thing to understand after all, is it? The important thing is to know that this programming language is essential when we talk about the current moment, totally focused on web applications. In addition to being a segment-oriented language, PHP is easy to learn and has a number of other advantages that make all the difference.

Node.js Developer Roadmap 2024 - Learn Node.js
Learn to become a Node.js developer
Do you want to learn Node.js but wondering where to start? This is the first question that comes to mind when we want to learn new technology.
Today, we bring you the Node.JS Roadmap, a comprehensive list of helpful resources & Node Js. tutorials that you can follow to get up and running with Node.JS.
If you are a newbie or intermediate Node.JS developer, this article contains the best resources to learn Node.js for you.
To understand what Node.js is, you don't have to be a great web programmer. But you need to have a basic understanding of programming environments.
What you need are the most common languages since Node.js is based on Javascript (hence the .js extension of your name).
As we anticipated in our post on the most used programming languages or the programming languages we should learn. Javascript is an interpreted language that is read and translated line by line at the same time the program is executed.
This language is used from the browser or client. But what if we needed to use Javascript on the server-side? That is when Node.js comes into operation, which has become one of the most used tools for web development today.
Node.js is a platform based on the Chrome JavaScript runtime that can easily build fast and scalable web applications.
Node.js uses an event-driven non-blocking I / O model, which is lightweight and efficient. It can seamlessly process data of all time and run on different devices.

What is Node.js?
Node.js can be defined as an open-source, cross-platform, dynamic JavaScript runtime framework or environment that is based on the Google Chrome JavaScript V8 engine. Developed by Ryan Dahl in 2009, Node.js was initially implemented as a client-side scripting language.
Today, it is used to run JavaScript code and scripts that run on the server-side to create dynamic web pages. The latest version of Node.js is 10.10.0.
If we could easily summarize what Node.js is, we could say that it is an open-source environment (Open Source), cross-platform and that it executes the Javascript code outside of a browser. And it is precisely the need to run this language on the server-side that makes Node.js.
In more technical terms, we can define it as a Javascript execution environment that is oriented to asynchronous events (the events do not depend on others having been previously executed) and that can build scalable network applications.
The term scalability refers to the ability of Node.js to make many connections simultaneously without having to read the code line by line or open multiple processes.
The fundamental objective of this “merger” is (among others) to load the dynamic content of the web pages before the page is sent to the user's browser. In this way, a more efficient load is produced and its visualization is expedited.
And yet, Node.js is not just that, since it serves a multitude of things as we will see later.
Who Uses Node.js?
Node.js was created by the original JavaScript developers with the idea of being able to run this language outside of the browser environment.
For this, they used Chrome's V8 engine. This engine makes Javascript become machine code (simpler) by making it faster and ignoring compilation. Therefore Node.js not only allows you to create interactive websites but also makes them more agile and capable of working with other sequence languages such as Python.
This makes developers use it especially in network applications that seek to be fast or in large projects where processes need to be agile, such as the development of APIs, web applications with Ajax, push messaging and, above all, everything, the Internet of things.
On the contrary, it is not suitable if we need to create applications that require a small number of connections with large consumption of resources (for example, calculations or data processing).
Advantages of Node.js
Among the possibilities of Node.js we find some advantages of this system.
- Node.js is based on the Javascript language, so there is no need to learn a new language separately, which lowers the learning threshold. At the same time, Javascript language is very important in web front-end development, especially HTML5 applications need to be used, so the unified front-end and back-end language can not only realize the full development of programmers but also to unify the public class library and standardize the code. This alone, Node.js has won the favor of the market.
- Node.js did not redevelop the runtime environment but chose the faster V8 browser kernel as the runtime to ensure Nodej's performance and stability.
- Node.js development is very efficient, and the code is simple, which prides itself on Node.js single-threaded mechanism. Another feature of Node.js is asynchronous programming, which gives Node.js obvious advantages in handling IO-intensive applications. Personally, we think that Node.js is 10 times more efficient than Java for web development and simpler than PHP code.
- The Node.js community is growing. Not only is the number of packages increasing rapidly, but the quality of packages is also significantly better than in other languages. Many bright star packages are simple and clever, designed for the usage habits of developers. The toolkits we use the most, such as socket.io, moment.js, underscore.js, async.js, express.js, bower.js, grunt.js, forever.js ..., are really changing my habits of previous programming.
Of course, in addition to my reasons for using Node.js, many companies also have their own reasons for using.
Node.js - Features and Benefits
Most web developers implement Node.js due to its amazing and powerful features. Some of the features of Node.js are:
- Faster code execution
- Highly scalable
- Non-blocking API
- No buffer
With these wonderful features, Node.js is widely used for building server-side and network applications. The following are the main areas where Node.js is widely used:
- I / O related applications
- Data transmission applications
- Real-time data-intensive applications (DIRT)
- JSON API-based applications
- Single-page apps
There are many companies using Node.js these days, such as eBay, General Electric, GoDaddy, Microsoft, PayPal, Uber, Wikipins, Yahoo !, IBM, Groupon, LinkedIn, Netflix, and many others.
Why did eBay Choose Node.js ?
It can be summarized in the following 4 points:
- Dynamic language: development efficiency is very high and the ability to build complex systems, such as ql.io.
- I / O performance and load: Node.js solves the I / O intensive problem very well, via asynchronous I / O.
- Connection memory overhead: Each Node.js process can support more than 120,000 active connections, and each connection consumes approximately 2K of memory.
- Operational: a Node.js monitoring system is implemented for the memory stack.
Areas Where Node.js is Not Suitable
Every language or platform has areas that are not good. For Node.js, the areas that are worst are CPU and memory programming.
- For computationally intensive applications, it is estimated that it is impossible to win with Javascript and C to fight for computational performance.
- Memory control, it is difficult to make Javascript and Java more complex data type definitions. Because object-oriented JavaScript is based on JSON, and Java directly uses the structure of memory. So through the process of JSON serialization and deserialization to control memory, Javascript has lost.
- For large memory applications, due to the memory design limitations of the V8 engine, the maximum heap in a 32-bit environment is 1G, and the maximum heap in a 64-bit environment is also less than 2G. If you want to read 10G data at once, it is impossible for Node.js Done
- Static server, although the advantages of Node.js are in IO-intensive applications, there is still a big gap from Nginx in the handling of static resources.
- Applications that do not require asynchronous: such as system administration, auto-script, etc., or Python is more convenient, the asynchronous call of Node.js can bring some problems to programming.
Node.js Application Scenarios
We have a preliminary understanding of Node.js and then we look at the Node.js application scenarios.
1. Web development: Express + EJS + Mongoose / MySQL
Express It is a lightweight and flexible Node.js web application framework, which can build websites quickly. The Express framework is based on Node.js built-in HTTP module and repackages the HTTP module so that the actual web request processing function.
Node.js is an embedded Javascript template engine that generates HTML code through compilation.
mongoose This is the MongoDB object model tool. Through the Mongoose framework, you can perform operations to access MongoDB.
MySQL It is a communication API to connect to the MySQL database, which can be used to access MySQL.
Usually, Node.js is used for web development, which requires 3 frameworks to work together, just like SSH in Java.
2. REST Development: Restify
Restify It is a Node.js based REST application framework, which supports both server and client. Restify is more focused on REST services than express, eliminating the template, render, and other functions in express while strengthening the use of the REST protocol, version support, and HTTP exception handling.
3. Web Chat Room (IM): Express + Socket.io
socket.io Uno is a software package based on the Node.js architecture and supporting the WebSocket protocol for constant communication. socket.io provides a complete package for building real-time applications in all browsers, and socket.io is fully implemented by javascript.
4. Web tracker: Cheerio / Request
heerio It is a specially customized toolkit for the server, fast, flexible and that encapsulates the main functions of jQuery. Cheerio includes a subset of the jQuery core, removing all DOM inconsistencies and browser incompatibilities from the jQuery library, revealing its truly elegant API.
Cheerio works on a very simple and consistent DOM model, and the parsing, manipulation, and rendering become incredibly efficient. Basic end-to-end benchmarks show that Cheerio is about eight times (8x) faster than JSDOM. Cheerio encapsulates the @ FB55-compliant HTML parser and can parse almost any HTML and XML document.
5. Web blog: Hexo
Hexo is a simple, lightweight and static blog framework based on Node. With Hexo we can quickly create our own blog, which can be completed with just a few commands.
When released, Hexo can be deployed on your own Node or GitHub server. For individual users, github deployment has many advantages, it can not only save the server cost but also can reduce the trouble of operation and maintenance of various systems (system administration, backup, network). So github-based personal sites are starting to get popular.
6. Web Forum: node club
Node Club It is a new type of community software developed with Node.js and MongoDB. It has a sleek interface, rich features, small and fast, and it's already in the Chinese Node.js tech community. CNode Get the app, but you can use it to build your own community.
7. Web Slide: Blade
Cleaver Can produce Markdown-based presentations. If you already have a Markdown document, you can make a slide show in 30 seconds. Cleaver is a tool for Hacker.
8. Front-end Package Management Platform: bower.js
Bower is a package management tool launched by Twitter. Based on the modular thinking of Node.js, it distributes functions in modules, so that there is a connection between modules and modules. This relationship is managed by Bower.
9. OAuth Authentication - Passport
Passport The project is an authentication middleware based on Node.js. The purpose of Passport is simply to "authenticate the login," so the code is clean, easy to maintain, and can be easily integrated into other applications.
Web applications generally have two types of login authentication: username and password authentication login, OAuth authentication login. Passport can configure different authentication mechanisms according to the characteristics of the application. This article will introduce the username and password authentication login.
10. Timed Task Tool - Later
Later It is a library of tools based on Node.js, which executes scheduled tasks in the simplest way. Later it can be run in Node and browser.
11. Browser Environment Tool: browserify
Browserify Appearance allows Node.js modules to run in the browser, use the require () syntax format to organize front-end code, and load npm modules. In the browser, compiled code calling browserify is also written to the <script> tag.
The operation using Browserify is divided into 3 steps. 1. Write the node program or module, 2. Use Browserify to precompile into bundle.js, 3. Load bundle.js into HTML page.
12. Command Line Programming Tool: Commander
It is a lightweight Node.js module that provides powerful functions for user command line input and parameter parsing.
The commander originated from a Ruby project with the same name. Commander Features: Self-Documenting Code, Automatic Help Generation, Short Parameter Merge (“ABC” == “-ABC”), Default Options, Mandatory Options, Command Resolution, Prompt.
13. Web Console Tool: tty.js
tty.js It is a command-line window that supports execution in a browser, it is based on the Node.js platform, it is based on the socket.io library and communicates with the Linux system via WebSocket.
Features: supports multi-tab window model; supports vim, mc, irssi, vifm syntax; supports xterm mouse events; supports 265 color screen; support session.
14. Client Application Tool: Node-webwit
Node-Webkit It is a fusion of Node.js and WebKit technology, provides a low-level framework for developing client applications on Windows and Linux platforms, and uses popular web technologies (Node.js, JavaScript, HTML5) to write platforms for Applications.
Application developers can easily use web technology to implement various applications. The performance and features of Node-Webkit have made it the world's leading web technology application platform.
15. Operating System: Node-OS
NodeOS is a friendly operating system developed with Node.js. The operating system is completely built on the Linux kernel and uses shell and NPM for package management. Using Node.js can not only carry out good package management, it is also very good. Management of scripts, interfaces, etc. Currently, both Docker and Vagrant are built using the first version of NodeOS.
FAQs - Node.js Developer Roadmap
Q1. What is the core difference between Javascript & Node Js. ?
JavaScript is a language. Node.js is not a language or a special dialect of JavaScript - it's just a thingamabob that runs normal JavaScript.
All browsers have JavaScript engines that run the JavaScript of web pages. Firefox has an engine called Spidermonkey, Safari has JavaScriptCore, and Chrome has an engine called V8.
✔️Blanche
Node.js adopts JavaScript syntax, endowing it with basic features such as flexibility, process orientation, and single-process and single-thread execution. Thanks to its flexible language, some object-oriented features can also be achieved through logic code.
Q2. What are the main security implementations within Node.js?
Open-source applications inherit any security and licensing issues from their open source components. The problem is that security testing tools like dynamic and static code analysis are ineffective at detecting open source vulnerabilities.

Q4. How can we differentiate in between spawn() and fork() methods in Node.js?
✔️ChrisCM
Ultimately you could use spawn in a way that did the above, by sending spawn a Node command. But this would be silly because the fork does some things to optimize the process of creating V8 instances. Just making it clear, that ultimately spawn encompasses fork. The fork is just optimal for this particular, and very useful, use case.

React JS Developer RoadMap 2024 [Updated] - Learn React.js
React Developer Roadmap
How to become a react developer in 2024? Do you find react as the best programming language to learn?
If so, then this blog is for you.
We will help you with the React Developer Roadmap that will guide you on your journey from being a novice developer to a skilled and experienced developer over time. Keep in mind that this roadmap is intended to share where to start learning, rather than just choosing the technology or tools that are trending today. So, let's start with the basics!
React Developer Roles and Responsibilities
React.js / React Native or React is a complete Javascript library used to create web application front-end or user interfaces. React is declarative, simple, component-based, fast, easy to learn, extensive, and supports the server-side of the application.
It has also caught the interest of the open-source community. React is currently being used by companies like Netflix, Instagram, Uber, Airbnb, Reddit, Linked In, etc. and it is compatible with Facebook.
Being a React Developer, you will be responsible for designing and implementing UI components on the web or mobile apps using the open-source library infrastructure. You also have to translate designs and wireframes into excellent quality reusable code.
Now, let's get into the roadmap you can follow to become a React Developer in 2024.
Learn ReactJS – Complete Roadmap for The React 2024 Developer
As mentioned above, this roadmap is only here to guide you in choosing the technology and tools you can learn to improve your skills and experience.
What is the Quickest way to learn React?
Roadmap to becoming a React developer in 2024. With the basic understanding of what it is to react and what your responsibilities will be as a react developer, let's go ahead and let you know the essential skills to become a react developer.
To become a developer, there are a certain number of common skills that you will have to learn, including:
1. Choose Your Programming Language
Regardless of the library or framework, you want to learn for web development, understanding the basics of the web, namely HTML, CSS, and JavaScript, is critical.
- HTML - Hypertext Markup Language or HTML is the standard for designing documents that will be displayed in the browser. Simply put, it is a language for web pages and it helps to create a website. And to become a react developer, you have to learn the basics, semantics, DOM structuring, and page sectioning properly.
- CSS: Cascading Style Sheets or CSS is a style language used to describe the presentation of the web page. It offers a simple process for adding style such as font colors, spacing, formatting, and layout to your document. For react development, you need to learn basic concepts, grid, flexbox, media queries, and responsive CSS web designs.
- JavaScript: JS is a lightweight programming language used to create web-centric applications. JavaScript corresponds to the ECMAScript specification. The basic JS concepts you need to learn JavaScript include syntax, basic operations, DOM manipulation, elevation, prototyping, event propagation, AJAX, and ECMAScript.
- React: You can't become a react developer without learning how to react. Therefore, learning the basics and all the other features of React is critical for anyone looking to become a React developer. Also, consider learning how to react from React's main website or any other authoritative source with vital information.
2. Build tools
Build tools are programs or software that automate the development of executable applications using source code. It incorporates code for linking, compiling and packaging into an executable format. Some of the build tools are Webpack, parcel, and Rollup,
The build tools include the package manager and task execution software, listed below:
Package Managers
- npm
- yarn
- pnpm
- Task Runners
- npm scripts
- gulp
- Webpack
- Rollup
- Parcel
Well, it’s not essential to learn all these tools, just learning npm and webpack should be enough for beginners. Once you have more understanding of web development and the React Ecosystem, you can explore other tools.
3. Style
For a react developer who will be responsible for the front-end of the web application, learning more about the style will not hurt. This is why you need to understand how CSS works, its frameworks, architecture, and how to use it in JavaScript.
If you are aiming to become a front-end developer like React developer, then knowing a bit of Styling will not hurt. Even though the RoadMap mentions a lot of stuff like CSS Preprocessors, CSS Frameworks, CSS Architecture, and CSS in JS.
We suggest you at least learn Bootstrap, the most critical CSS framework you will end up using every now and then.
And, if you want to learn bootstrap, if you're going to go one step ahead, you can also learn Materialize or Material UI, along with some react development tools.
Popular React Native Developer Tools to Know
Tools, libraries, and services are an important part of every developer's life, no matter what environment they are developing for. We will walk you through some of the best user interface frameworks, libraries, components, development tools, and web services that will make a React Native developer happier and more productive.
Text Editors and IDEs
Visual Studio Code is a text editor that has built-in IntelliSense, debugging, and Git integration capabilities. What makes it really good for native react development is the Native tools extension. This allows you to run React Native commands from the command palette, add IntelliSense to React Native API, and debug code in the editor itself.
If you are using Atom, you can install the Nuclide plugin. This plugin was specifically created to work with React Native, Flow and Hack projects. It has a built-in debugger and element inspector with all the features that you are used to in Chrome developer tools. Support flow means you get AutoComplete type hints and diagnostic code out of the box.
Development tools
Development tools are broad in scope, so we are grouping each tool based on its approach:
- SDK
- code quality
- flow
- depuration
SDK
When it comes to SDKs to react native, nothing beats Expo. Expo allows you to easily prototype an application without the need for Android or Xcode studio. It includes a set of components and libraries to help speed up your development.
The Expo workflow consists of the following:
- Create a new project using create-react-native-app.
- Write the code in your favorite text editor.
- Run the application using the Expo client application.
There is no need to connect the phone to the computer. Simply scan the QR code on your terminal with the Expo client application, and the application will automatically launch. If you use Genymotion, Expo is supported.
The only downside to using Expo is that any custom package that uses the native functionality of the device can be included. Expo already includes a series of native packages used as a camera, Facebook, and map.
But if you need to use a package that they no longer support, then you're going to have to "eject" it from your application. At that point, your application will be as if it was created with react-native init, and you also lose the ability to run with the Expo client application.
Code quality - Checking the quality of your code is important, and that is why tools like ESLint exist. In summary, a fluff tool allows you to be more consistent with the verification code against a style guide.
An example of a style guide is Airbnb's Style Guide is JavaScript which specifies the rules for how JavaScript code should be written. The fluff tool then checks your code against those rules to ensure they have been followed. There is also a style guide for React projects.
If you are using Sublime Text, here is a good tutorial on how you can configure it so that you can have real-time feedback on the quality of your code while you're coding: Sublime Linting for React and ES6. If you use another editor or IDE, be sure to look for a corresponding plugin that uses ESLint.
Flow - If you want to add static typing to your project, you can use Flow. Flow adds static-writing in JavaScript without having to make changes to your existing codebase. This is because the flow tries to deduce the type whenever possible. For new projects, however, it is recommended to explicitly specify the type to reap the benefits of using flow.
Test - The enzyme is a reactive test utility that allows you to assert, manipulate, and traverse that your component's output. Provides methods of how shallow()to "superficially" render its components, find()to traverse the rendered component, and expect()to affirm the columns or content in the component.
Depuration - Reactotron is a desktop application that allows you to debug native react and react applications. Some of its key features include inspecting, modifying and subscribing to the application state, tracking HTTP requests through the application.
Also, benchmarking the operation of the application and tracking errors. If you use Redux, it can even send actions and track sagas from within Reactotron.
Boilerplates and UI Frameworks
Snowflake is a model for full-stack react native development. It includes everything from the front-end to the back-end of the application. So if you want a tool that can get you started quickly then you might find Snowflake useful. You can read the notes for more information on what packages and tools are used to put up.
Alternatively, you can use Ignite. It is a command-line tool that also includes a boilerplate, generators, style guide for UI components, API testing tool, and much more.
React Native already comes with user interface components that you can use for user interaction. The problem is that they only have the most basic style in order for each component to be distinguished by what it is (eg button, check box). If you want to add the custom styles, you have to write your own CSS code.
This is where NativeBase allows your application to have a truly natural appearance by applying the same layout used in native Android (Material design) and iOS applications (Human interface guides). Out of the box, you have components such as Action Buttons, Spinners, and best of all, form components.
Libraries and Components
React Native has a great community behind it, so there are a ton of libraries and components that you can use. We could spend all day talking about them, so to keep things short, to focus on the following areas
React Navigation - It allows you to easily implement React Navigation in your native applications through its built-in browsers like Stack Navigator, Navigator Tab, and Drawer Navigator. That's not all, however: in addition to in-app navigation, it also includes deep linking, Redux integration, and web integration. This is a very robust library for the navigation application.
State Management - MobX provides the functionality to update and manage the state of the application used by React. What makes a good candidate for state administration in React is its simplicity and testability. It also has a short learning curve, as well as async functions and computed values, are already handled behind the scenes.
The state is the representation of a system at a given moment. Refers to data stored in the form of an array, objects, or strings in the application. So, state management is a method of state organization. The main components of state management that you must understand are the following:
Helpers
- Reselect
Asynchronous actions
- Redux Thunk
- Best Redux Promise
Redux-Saga
- Redux Observable
Data persistence
- Redux persists
- Redux Phoenix
For larger and more complex applications, Redux is still recommended. This is because MobX is very liberal, not unlike Redux, which provides strict guidelines on how status should be handled. So it's a smarter option for bigger projects with more people working on them.
Animations - Native React already has an animation API built into it. In fact, there is not just one, but two APIs for working with animation: Animation API and Layout Animation.
Both are very powerful but can be cumbersome, especially if all you want to do is apply basic animations like moving an object up and down or whatever is bouncing. In such cases, components like Animatable come in handy.
Best React framework and component libraries in 2024
Here is a list of components and libraries that are used in react-native projects. These are compatible with iOS and Android devices:
- Styled-components: allows you to write CSS code to style your components react.
- React-native-calendar: displays a calendar that users can interact with.
- React-native- datepicker: to choose dates and times.
- React-native-progress: to create progress bars and spinners.
- React-native-spinkit: a collection of load indicators.
- Vector Icons: This allows you to use the icons from your favorite icon font fonts like Awesome Font and Material icons.
- react-native-swiper: convert a collection of images or containers to pass the components.
- React-native-scrollable-tab-view: Navigation tabs that you can slide between.
- React-native-lightbox: to view images in full screen pop-overs.
- React-native-maps: allows you to integrate Google Maps into your applications. Not all functions available in the Google Maps API are available, but the functionality it provides should be sufficient in most cases.
- SGListView: A memory-friendly implementation of the ListView's native React built-in component. If you need to display huge lists in your application, use it instead of ListView.
- Formik: makes dealing with native forms react less painful. It allows you to obtain values in and out of the state of form, validate your forms and control their presentation.
- React-native-i18n: to implement the internationalization of your applications.
- React-native-push-notification: implement local and remote push notifications.
- InstantSearch - A collection of components for the search application.
- React-native-fs: allows you to access the device's native file system.
- React-native-camera: a camera component that allows you to take photos and videos from your app.
- react-native-video: to play videos from your file system or from a URL.
- react-native - sqlite- storage : to store and manipulate data from a SQLite database.
- react-native-store: a key and value store based on AsyncStorage.
- react-native -webrtc: to implement WebRTC.
Web services
You can create server applications and facilitate the deployment of your native reactive applications by using web services. There are a plethora of web services out there, but we will focus on the following areas:
- database
- Analytics
- push notifications
- code updates
- continuous-integration
Database
Realm is a real-time database with a focus on mobile applications. It includes features such as two-way data synchronization, front-line capabilities, and data push. The Reino mobile database is open source and cross-platform, which means you can host the Realm Object Server on your own server and then use the Realm JavaScript Library for free.
Not all functions are available in the developer edition, but in most use cases you should be fine with just the developer edition as it includes the core functions such as the database object, real-time synchronization, and the authentication. Here's a comparison of what you get for each edition: Realm Products and Pricing.
If Realm is too much for your needs, you can always stick with the AsyncStorage API that comes with React Native.
Analytics
Fabric.js is an all-in-one service that allows, among other things, to add analytics in your application. Hay Answers, which gives you real-time statistics on how your application is being used. This includes the number of active users, the length of the session, and the retention rate.
There's also Crashlytics, which offers you powerful crash reporting capabilities. Everything happens in real time, and can be viewed on the web's real-time dashboard. You can use the Fabric library to easily configure the fabric for your native React application.
If it would look good with a tried and true solution like Google Analytics, there is also a library that allows you to do that.
Push notifications
There is no competition when it comes to the application of in-app push notifications. Advanced bases Cloud Messaging (formerly known as Google Cloud Messaging) allows you to send push notifications for Android and iOS applications. You can use the react-native-fcm package to communicate with FCM from your application.
Code Updates
CodePush enables you to deploy code updates for mobile apps directly to user devices. CodePush acts as a central repository where you can implement changes to assets such as images, CSS, JavaScript, and HTML. The corresponding CodePush code in the application would then pull these changes. This is great for pushing bug fixes to the app without uploading to the app store and waiting for users to update the app. You can use this package to pull CodePush updates into your native React application.
Continuous Integration
Bitrise is a continuous delivery service for mobile application development. It allows you to run the tests, build the application, and automatically push it to user devices each time the code is deployed.
Bitrise integrates with a ton of services at every step of your development workflow. For example, when you push their release branches on GitHub, Bitrise receives the notification of that push through webhooks. Then it will start running the tests. Once the tests pass, the construction process begins.
If it is just a "soft release" (eg changes to the JavaScript code) then they can implement the changes to users via CodePush. But if there are changes to the native code (eg added a camera plugin), then Bitrise can also build an APK or IPA file to deploy on Google Play or iTunes Connect.
Fastlane is a collection of tools that automate the process of building and launching Android and iOS applications. For iOS, it takes care of tasks such as running tests, generating images, signing code, and launching the application to the app store.
It also includes beta testing tools like Pilot and Boarding. Pilot allows you to upload your application to iTunes Connect and manage your TestFlight beta-testers from the command line. Interns creates a registration page for TestFlight beta-testers.
The tools are geared more towards iOS deployment, but they can also benefit if you're deploying Android apps. Currently, there are only two tools for Android implementation: Supply and Screengrab.
Supply allows you to automate the loading of assets such as the application icon, promo graphics and images of your application. It also allows you to update your existing apps on the Google Play Store.
Screengrab, on the other hand, automates the generation of images for various devices. You can also localize each screenshot if your application supports multiple languages.
React JS FAQs: The Most Common Questions
Q1. How much does it cost to build an eCommerce website using Node.js and React.js?
1. Deployment cost (AWS/Azure).
2. Development cost.
The development cost comes to the amount of customization being done which involves developing themes from scratch, 3rd party integration, implementing secure gateways, etc.
The cost of building a small to large and complex store could be between 500$ to upwards of 30,000$.
Your costs would be limited to whatever your AWS or Azure deployment cost, plus whatever your payment services were.
That’s assuming you build the app yourself. You can build a sophisticated Node/React app using entirely free tools like VS Code and Postgresql.
If you want to hire someone to build that site for you and you want to have a solid, reputable development team create your code, you’re probably looking at a minimum of 25,000 USD.
Q2. How long does it take to build a web application with React?
- How do you define a simple app?
- Comfort level with the technology
- How large a team is building the app
- If you’re building it on your own, is this a fulltime gig or a side project?
This is not exclusive to React. I would ask the same questions for all frameworks
Your app can be anything from a couple of pages to a large scale application that's still “simple” in nature.
If you're looking to build a simple to-do list, it can take a developer anywhere from half an hour to a couple of days depending on the proficiency with the framework.
I've been working with react and react Native for quite some time now and with create react app I could probably have a to-do list running in half an hour.
So again, it really depends.
Q3. What are the popular React-based frameworks?
There are two all-in-one options that I’d check out. The first is Next.js and it has server-side rendering for good SEO, routing, and a whole lot of plugins for handling everything such as CSS or styled components.
Another great option is Gatsby. This generates static pages which make it great for hosting on an S3 bucket but does not have an active server like Next.js so it isn’t quite as good for generating SEO optimized pages on the fly.
Q4. Is React still worth learning in 2024?
React is a JavaScript library that was created by Facebook. It's used to build user interfaces and it's very popular in the industry. In fact, it has been used by more than half of the top 10,000 websites in the world.
React is a great technology to learn because it will help you with your job search and even get you better jobs.
Q5. What is the future of React developers? Are React developers in demand?
The future of React developers is bright. We’re still in the early stages of this technology, and the React community is growing at an exponential rate. This means that there are many opportunities for new developers to get involved with React applications.
The demand for React developers will only continue to grow as more companies start using the framework to build their applications. The need for skilled developers will also increase as companies look to build new features on top of their existing applications.
If you want to be prepared for these changes, then learning how to code in React Native is a great way to get started.
Conclusion
That is all! In this article, you have learned about some of the tools, libraries, and services that you can use when developing React Native applications.
This roadmap for React developers can be very helpful if you are starting your React Native journey.
It sure won't be easy, but by following this roadmap and guide, you will become the React developer you always wanted to be.

FAQs about Python Developer Roadmap 2024
Q1. What is the best way for an easy quick-start in Computer Science and Python Development?
I really like MIT Introduction to Computer Science and Python. There is an older version of the course with Professor John Guttag that I prefer because of his mannerisms and teaching styles, but the newer one is equally as good.
MIT 6.00SC Introduction to Computer Science and Python 2011 110
MIT 6.001 Intro To Computer Science and Python Fall 2016 39
I recommend Python for Everybody from the University of Michigan. Lecture videos, auto-graded assignments, etc are all available for free at www.py4e.com
Q2. Why Python is so popular and what are the benefits of using Python?
It is the easiest language to learn these days and Coding Ninjas makes it easier, also a lot of students are going towards it for their future career and a better way ahead. I too was interested in it after my first year of engineering and wanted to learn it and be a programmer using Python.
Q3. What is the advantage of using a namespace in Python programming?
It is very common to reuse the same name in different libraries. e.g. in Java, there are multiple libraries with an Object, String, Array, List, Queue, Map, Set, Error class/interface.
Without namespaces (or packages) you would have no way to use these libraries together and to distinguish which one you were referring to.
Q4. How do you convert a number to a string, using Python?
Conversion to a string is done with the builtin function, which basically calls the __str__() method of its parameter.
For someone who wants to convert int to string in specific digits, the below method is recommended.
month = "{0:04d}".format(localtime[1])
In Conclusion
Python is a great first language as if it's your second, third, or nth language. Its learning curve is less harsh than others, it has thousands of libraries that allow us to do what we propose in a few lines of code. It allows you to evolve quickly, in addition to delving into more complex tasks, as you gain fluency.
Obviously recommending a programming language is complicated. It depends on many factors such as the user that you are going to give it to. Nor is it the same to recommend a language to someone who is just starting to program as to another programmer with extensive experience in various programming languages.
As we said above: this is not a language war but due to the current momentum of Python, you should hire RedBlink’s team of experts in Python, since it may be the language that helps you in your next project.
Nowadays, data suggests low-code/no-code tools are actually opening doors for such non-developers. 60% to 70% of companies said non-developers in their company already build tools for internal business use, and nearly 70% – 80% predict to see more of this trend in 2024.
Twitter SEO: Increase Your Google Search Visibility in 2024
Twitter SEO 2024
If you know how to use product placement or influencer marketing to get your name in front of people, great, you’re a brand coach. Just like that, exposure isn’t the end of the road. You still need a SEO friendly content plan for ongoing social engagement, to give yourself that elusive goal of “sustainable growth.”
With an account, content, and following size, you can market your products and services more effectively.
You will find that people searching for a product or service may have a limited amount of time to search for it. That’s because the value proposition of those products and services add value to people’s lives.
They give them more purpose.
If you can directly add value to that search, by promoting that product or service or sharing that piece of content, you’ll be giving them more value than you realize.
Luckily, for both of those situations, social media may be an answer, especially the Twitter SEO. Most people won’t pay you, but that doesn’t mean you can’t win. Every time you publish content, you’ll generate social proof, which can push back content you already created to the top of the Discover pile.

AWS EC2 Instance Types - Compute Optimized EC2 Instance
Amazon Ec2 Instance Types
Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides secure, resizable virtual space in the cloud.
It aims to develop better web-scale cloud computing keeping the requirements of the developers in mind.
Amazon Elastic Cloud Compute EC2 is a robust web service interface. It lets you run on Amazon’s proven computing environment providing full control.
Elastic Cloud Compute (EC2) instances arrange for the resources acting as the backbone of most cloud deployments.
Amazon has created different EC2 type instances to deliver customizable and scalable server options.
Let’s understand AWS EC2 instances in details.
What are the benefits of AWS EC2?
Amazon Web Services’ resources are rapidly adopting technology changes to stay at the top position and to multifold their business profits.
For cloud deployments, Elastic Cloud Compute (EC2) instances serve as the backbone of the resources provided to the clients.
In the simplest form, EC2 instances are like the server points for which we pay to web hosting companies.
Instead of web hosting companies, here we are accessing one of the EC2 instance types to run our service using Amazon’s resources.

Building Blocks of EC2 Instances
The latest cloud storage and wireless technologies have brought a revolutionized change in the way we broadcast our business reach.
Amazon EC2 instance types that provide hi-tech, improved, and secure methods.
Top Most Security with AWS Nitro System
The selection of the instance types you choose depends on the hardware of the host computer. Each instance has a different memory specification and computing type.
The instances having different capabilities are listed by the AWS. You have to select the instance types depending on your requirements of application or software that you plan to run on your instance.
Amazon allocates some resources such as CPU, memory, and instance storage when a new instance is created.
Also, Amazon EC2 shares hardware information such as the network and the disk subsystem of the host computer in the list of created instances.
The purpose of listing this information is to use shared resources. Each instance type provides higher or lower minimum performance from every shared resource.
However, EC2 instances using the nitro system is the next-generation technology that offloads the traditional virtualization functions.
There are dedicated hardware and software deployed to achieve high performance, availability, and security while reducing virtualization overhead.
The Nitro System is flexible and easy to design and rapidly deliver new EC2 instance types using shared instances.
Choice of processors
The latest generation Intel Xeon, AMD EPYC, and AWS Graviton CPUs enable you to use EC2 instances cost-effectively.
EC2 instances powered by NVIDIA GPUs and AWS Inferential are also there for workloads.
These machines help you run heavy applications such as machine learning, gaming, and graphic-intensive applications.
High-performance Storage
Amazon EC2. Instances provide better and secure storage. Amazon EBS is offered to serve the need of storage for the large volume types.
It allows you to optimize storage performance and cost for workloads. Many EC2 instance types support local NVMe SSD storage.
Enhanced Networking
AWS offers 100 Gbps enhanced Ethernet networking for compute instances which is the highest among all other services.
It helps to improve higher packet per second (PPS), lower network jitter, and lower latency.
Elastic Fabric Adapter is the preferred network interface for Amazon EC2 instances for running high-performance computing (HPC) applications.
The benefits of this are the low-latency, high-bandwidth interconnect between compute nodes.
Improved EC2 Instances with Fair Prices
If you are already using or a new user then the most important thing is to stay in touch with the changing types of EC2 instance types and the changing specifications of models and sizes.
The basic instance types remain the same but due to structural changes, there is a certain change in prices and the features offered.
Depending on your budget and workload, you can choose from a Reserve Instance purchasing listing with 1-year or Flexible RI offerings.
AWS EC2 Instance Types
EC2 instance types can be commonly categorized as:
General Purpose:
AWS provides this environment for web servers, development, and other common applications.
Compute Optimized:
Specially designed to compute-intensive applications such as some scientific modeling or high-performance web servers.
Memory-Optimized:
Designed to handle applications that need greater memory to run. Some applications like real-time big data analytics or running Hadoop or Spark are some of them.
Accelerated Computing:
This provides the provision to access additional hardware (GPUs, FPGAs) required for parallel processing for tasks such as graphics processing.
Storage Optimized:
Designed to execute special tasks that require huge amounts of storage, specifically with sequential read-write, like log processing.
A chart of AWS EC2 types
EC2 Instance Type: Detailed Study
Type: General Purpose
General-purpose instances are good to make a start using the AWS environment. With all the basic functionality, it is a cost-effective cloud environment that can effectively run mobile apps, web apps, RP and CRM apps, etc.
In this class, there are fixed and Burstable performance instances. Burstable performance EC2 instances allow you to quickly scale up your computing environment at an affordable price.
That means you can anytime upgrade your service by opting for higher range EC2 instances.
General Purpose: A1
A1 instances are general and make use of the ARM-based platform, as opposed to Intel or AMD. ARM Platform supports open-source software such as Java and Python. The multiple architectures also use the ARM platform.
General Purpose: M5
M5 instances are developed using x86 architecture and run on Intel Xeon processors. They offer higher compute memory, and network performance in comparison to A1.
M5 instances can be deployed for development and testing. They also offer support for Intel AVX-512, a set of CPU instructions supporting the encryption algorithms.
Therefore for higher security, you can opt for these instances types. Also, improved performance is ensured.
General Purpose: T3 and T3a
Another use of Burstable instances is T3 and T3a that uses Intel and AMD processors.
Burstable performance instances are slightly less powerful than the fixed performance instance (like an M5).
But to handle heavy workloads, you can opt them at a budgeted price.
These bursts are handled by CPU credits. That means you earn CPU credits when you are not running at maximum processing.
How much you can earn depends on the time at a low threshold and depending on instance type size. The credits can be used when you need to burst.
Type: Compute Optimized
Compute Optimized: C5
For applications such as gaming servers, scientific modeling, high-performance web servers, and media transcoding, compute instances are ideal to use.
They run on Intel Xeon Platinum processors at a speed of 25% faster than C4 instances. The higher speed is much useful in running bigger applications without any buffer.
Type: Memory-Optimized
Memory-Optimized: R5 & R5a
Intel and AMD have other offerings for memory-optimized instances. R5 and R5a instances are specially created for memory-based applications such as real-time big data analytics, large in-memory caches, and high-performance databases.
The R5 and R5a instances work together with the AWS Nitro System that allows them to access the compute and memory resources of a server.
As a result, the optimization saves your money on a per/GB basis
Memory-Optimized: X1 & X1e
X1 and X1e instances are designed to provide high memory resources for computing with the X1e family.
They offer the highest memory ratio among all the EC2 instances. The intensive use of these instances is done in applications like SAP HANA, and other real-time applications.
Memory-Optimized: High Memory instances
High Memory instances provide 6 TB, 9 TB, or 12 TB of RAM which is the highest among the single instances type.
High Memory instances are designed for the use of Dedicated Hosts on a 3-year Reservation. This means that you will purchase them for at least 3-years. Instead of that, you will get the security benefit on a dedicated host.
You will have your server rather than using the AWS server on a shared basis.
Type: Accelerated Computing
Accelerated Computing: P3, G3, F1
As we have many applications that are graphics-based, especially online gaming applications.
There are special accelerated instances type that makes use of Graphical Processing Units (GPUs) or Field Programmable Gate Arrays (FPGAs).
They will optimize special tasks such as graphics processing or floating-point number calculations. The instance offerings are:
P3: It has a parallel processing ability used for general machine learning tasks.
G3: These GPU offerings are for graphics-based applications such as rendering, encoding, and streaming.
F1: These instances make use of FPGAs accelerated processing. The cab is used for advanced offerings and enhancement. With the help of FPGAs, you can get custom AMIs(called AFIs) that offer quicker deployment and development options.
Type: Storage Optimized
Storage Optimized: H1 & D2
For dense storage providing access to high sequential read-write for large data sets, like distributed Hadoop deployments, H1, and D2 instances are used.
These instances have huge storage on HDD, with H1 providing a maximum of 16 TB and D2 providing a maximum of 48 TB.
Storage Optimized: I3
I3 instances offer storage on SSD with 16 GiB. However, these instances provide lower latency than HDD-based storage.
They also make use of AWS Nitro System offerings for optimized access to memory and computer resources. This is called Bare Metal Access.
Getting Real Experience With EC2
AWS keeps introducing new EC2 instance types throughout the year. So, if you are new to AWS services or a regular user, you can keep a track of these instances types to improve your service and to use the AWS resources in a better way.
The hands-on experience gives you a more clear idea of the usage of EC2 instance types.
There is a provision that without making changes in the real-time applications, you can check the working of the new instances and upgrade the same.

How To Setup EC2 Instance in AWS - Amazon EC2 Security
To access AWS Cloud services, Amazon has provided a simple, scalable, fully managed Elastic Cloud EC2 Instances types. These instances provide complete support to work with advanced applications and tools.
Whatever instance type you make use of, a common data source for workloads allows using multiple instances from more than one server.
It is vital to understand the working of the EC2 instances types keeping the AWS security in mind, along with patching responsibility, key pairs, and various tenancy options.
Through this post, we have made sincere efforts to make you understand about AWS Shared Responsibility Model before and instance-level security within your Virtual Private Cloud (VPC).
Here, we are discussing, how to protect EC2 instances by applying AWS security patches to your instances and multi-tenancy options.
Let’s dive in to learn the fundamentals of AWS services through EC2 instances because that will be required to compute applications and run projects.
AWS security groups and instance security
To provide security at the protocol and port level, AWS security groups (SGs) and EC2 instances play a vital role.
The AWS security groups are like a firewall that contains a set of rules.
It tracks the traffic coming and going out of an EC2 instance.
Like the network access control lists (NACLs), no deny rules are followed. If a data packet is permitted, it will not be dropped.
When you are accessing the AWS security groups, you have to restrict the data access privileges by making the changes in the permissions. You can develop your security restriction as per the individual need.
However, a guideline by AWS is provided on setting the permissions that clarify data access should be minimum. Only one or two people should be allowed to access the resources.
This is designed so to prevent the security breaches and for the effective use of EC2 instances.
Setting EC2 Instance in AWS
Sign up for AWS
A sign up for Amazon Web Services (AWS) will authenticate you to access Amazon EC2. The payment is taken as per the use.
The new users can start by creating a login as an AWS customer
- To create a new account:
- Open https://portal.aws.amazon.com/billing/signup.
- Follow the online instructions.
- The verification code will be sent to verify your account
Create a key pair
Login information is stored using cryptography. The public key pairs are used to access the EC2 instances type. Once you log in, you get a private key hat that can be used with SSH.
The key pairs can be created from the Amazon EC2 console. For each separate region, you need to create a different key pair for the same instance type.
To create a key pair, you can use one of the following methods.
A proper name is given to each security group just to differentiate from one another. The description is optional, but no additional information is needed. Security groups are specific to a VPC.
Note: Choosing a correct VPC will ensure the security of the instances types.
Create a security group
The security groups are an effective way to secure the AWS elastic file system that acts as a firewall for the various instances types.
The rule which you form for the security group will enable you to connect to your instance from your IP address using SSH. You can even apply the rules for giving access through http or https.
Prerequisites
The security group editor in the Amazon EC2 console detects a public IPv4 address to confirm your IP.
In case you are connected through an Internet service provider (ISP) or from behind a firewall without a static IP address, you need to find out the range of IP addresses used by client computers.
AWS security groups: Rules
Inbound and Outbound tables are the source for creating the security group rules.
The AWS security groups have a stateful rule, that allows traffic into an EC2 instance, will automatically allow responses to pass back out to the send.
The outbound process doesn't wait for an explicit rule in the Outbound rule set.
There are five fields pf each rule:
- Type
- Protocol
- Port Range, Source, and
Description: Both Inbound and Outbound rules follow this ruleset.
Security Group Rules
Type: From the list, you can select the protocols like SSH, RDP, or HTTP. You are allowed to select a custom protocol.
Protocol: Here you can specify the protocol details such as TCP/UDP, etc.
Port Range: It takes the default port setting but sometimes you have to use a custom port.
Source: it can be set in a network subnet range with a valid IP address. the access can be left blank to the entire internet using the “Anywhere (0.0.0.0/0)” value.
Description: This field allows you to add a description of the rule that has been added.
Creating a security group
The security groups can be created in different ways such as using AWS CLI or the AWS Management Console. AWS Management Console allows you to create a security group during the launch of an EC2 instance.
Configure Security Group
You can create a security group without EC2 instance, do the following:
- Access AWS Management Console by login
- Choose EC2 service
- Choose “Security Groups” from the available categories on the left
- Create a Security Group by selecting the blue button
- Provide a name to the security group and give a description
- Choose VPC
- “Add Rule” by using a button
The default limits are set during the creation of security groups. They are
- VPC = 2500 per region
- Rules per security group = 120 (no more than 60 inbound and 60 outbound)
- Security groups per network interface = 5
OS Patch Management
While accessing EC2 instance type , a separate security group is required even if you are accessing a secured AWS.
You have to look for security patches on regular basis. New vulnerabilities and security flaws are being discovered and fixed from time to time.
Moreover, you can’t afford to ignore them as AWS security is the utmost priority to run safe applications.
Once an EC2 instance type is created, patches can be downloaded after checking the details of the patches.
The auto-update feature can be used through the instances used.
For example: yum update -y
Configure Instance Details
The installation of the latest patches provides security to instances types against vulnerabilities and threats. Applying it is a simple yet mandatory process.
Multi-tenancy vs dedicated
Tenancy is related to your host EC2 instances types. To be precise, with your physical server within an AWS Data Center.
During the deployment process of instances, you can specify 1 of 3 tenancy options for your instance:
Let’s go through the pros and cons of the same.
Shared Tenancy: This type of tenancy will launch your EC2 instance on available hosts with the required resources to run instance type. This will not have any effect on the other hosts sharing the same instance type.
AWS implements advanced security mechanisms that keeps the two hosts separate while using the same EC2 instance type.
Dedicated Tenancy: Here the tenancy is related to both dedicated instances and dedicated hosts:
Dedicated instances are related to hardware resources used by an individual host. In this case, you have to log in using your AWS account.
This will protect your hardware resources and you are doing it separately for the instances types that you are using because of the AWS internal security policies.
You need to pay extra charges for it as you are restricting other hosts to access the instance type. However, it is not of many benefits as there are hardly any issues regarding hardware security.
On the other hand, dedicated hosts offer additional visibility and control over placing your instances on the physical host.
The different software suites with liceneces can be used such as VM ware, Windows, Linux, etc. The benefit is the ability to use the same host for several instances.
Note: Shared tenancy reduces the overall costs. All instance types can’t get connected through the dedicated tenancy, so if you are thinking of using it, consult the AWS documentation.
Amazon EC2 key pairs and Linux instances
Once everything is set to use EC2 instance type, the question comes as to why key pair should be created and for what it is used for?
As we have already discussed above that a key pair is the combination of a public key and a private key.
The main function is to provide cryptographic security to secure the instances types.
To refresh from the back, during the creation of an EC2 instance you have downloaded the key pair. We hope that you are preserving that file.
Why we are mentioning this here is because the same key pairs can be used for the multiple instances and you don’t have to create a separate key for every instance type.
For the first time usage of the EC2 instance type, you need to put the detailed information of the keys. Once the access is provided, a simple login will allow you to enter in.
A Closer Review
AWS has made it clear on several occasions that maintaining EC2 instance security is the responsibility of the host.
In such a case, our intention through this post is to make you aware that after getting connected to an AWS security group, don’t leave the chance to become vulnerable to attacks.
You must ensure:
- Deploy a patch management policy during the creation of EC2 instances types.
- Instance tenancy should be decided considering cost and additional security features and needs of the application.
- Finally, manage EC2 instance key pairs by restricting the use of private keys while ensuring instances security.
