Did you know that AWS leads the cloud infrastructure industry with a 31% market share, followed by Microsoft Azure (24%) and Google Cloud (11%) in Q4, 2023?

Optimizing costs has become a top priority as businesses continue to migrate to the cloud. With Amazon Web Services (AWS) being one of the leading cloud providers, it’s essential to understand the best practices for cloud cost optimization

Global cloud infrastructure service spending grew by $12 billion in Q4 2023 compared to Q4 2022, totaling $73.7 billion for the quarter.

The traditional approach to budgeting and procurement doesn’t align well with cloud computing services, leading to overspending.

Here, we’ll discuss the most effective ways to reduce AWS costs and improve your bottom line.

AWS Cost Optimization Best Practices in 2024

Managing cloud costs can be a complex task, but with the right strategies in place, you can achieve significant savings. Here are some key best practices to help you optimize your AWS cloud costs and maximize your return on investment (ROI).

Let’s have a look!

1. Understand Your AWS Bill

The first step in optimizing your AWS costs is to understand your bill. 

According to the research, companies waste, on average, 35 percent of their cloud spend, equating to $6.4 billion in annualized wasted cost for AWS alone.

To avoid unnecessary expenses, you need to know what you’re paying for and identify areas where you can cut back.

Here are some key components of an AWS bill that you should keep track of:

  • EC2 instances: These are the virtual servers that run your applications. Ensure you’re not overprovisioning Amazon EC2 Instance Types or leaving instances running when they’re not in use.
  • Relational Database Service ( RDS ): This is a managed relational database service. Monitor your database usage and adjust instance sizes accordingly.
  • Amazon S3: This object storage service can quickly add up in terms of costs. Consider using cheaper storage options like Glacier or Cold Storage for infrequently accessed data.
  • Data transfer: Keep track of data transfer rates between regions and availability zones. You can save money by choosing the right region and availability zone for your workload.

2. Reserved Instances vs On-Demand Instances

One way to optimize your AWS costs is to choose the right type of instances. Reserved Instances (RI) offer significant discounts compared to On-Demand Instances. 

According to AWS, customers who purchase RIs can save up to 72% on their costs.

However, there are certain conditions to consider before committing to RIs. For example, if your workload requirements change frequently, On-Demand Instances might be a better fit. Additionally, RIs require a one-year commitment, so you’ll want to carefully plan.

3. Specify the scaling strategy – AWS Auto Scaling

Another effective way to optimize your AWS costs is through auto-scaling. By automatically adding or removing instances based on demand, you can ensure that you are only paying for what you need.

There are three main types of auto-scaling:

  • Scale in: Remove unneeded instances to save costs during low-traffic periods.
  • Scale-out: Add new instances to handle increased traffic.
  • Step scaling: Adjust instance counts gradually based on predefined thresholds.

Scaling decisions can be automated based on changes in demand, optimizing availability, costs, or a balance of both.

4. Work with Spot Instances

If you have workloads that can tolerate interruptions, consider using Spot Instances. These instances are available at a much lower price than On-Demand Instances but come with the risk of termination upon notice.

Users can save up to 90% on their costs by using Spot Instances.

 However, it’s essential to design your application to handle interruptions gracefully.

5. Optimizing your cost with Rightsizing Recommendations

Rightsizing involves matching your instance types and sizes to your actual workload needs. According to Bain & Company, rightsizing can help reduce costs by up to 30% to 60%.

To rightsize your instances, follow these steps:

  1. Monitor your instance utilization using APM Tool – Amazon CloudWatch.
  2. Identify underutilized instances and downsize them.
  3. Identify overutilized instances and upsize them.

6. Cost Allocation – AWS Cloud Financial Management

Effective cost allocation is critical to optimizing your AWS costs. You can use tags to categorize your resources and track usage across multiple departments or projects. This will give you better visibility into your spending patterns and help you identify areas where you can cut back.

7. Optimize Data Transfer Cost

Optimizing data transfer costs is essential for cloud cost optimization, as it can significantly impact your overall cloud spend.

Here are some of the best ways to optimize the data transfer costs:

I. Choose the right data transfer option

AWS offers several data transfer options, including:

  • AWS Inter-Availability Zone (Inter-AZ) 
  • Traffic, 
  • Intra-AZ Traffic, And 
  • Public IP Traffic. 

Each option has different pricing models, and choosing the wrong one can result in higher costs. 

For example, using public IP traffic for data transfers between instances in the same availability zone can be up to 4 times more expensive than using Inter-AZ traffic. 

II. Use data compression

Data compression can help reduce the amount of data being transferred. It can lower your data transfer costs. AWS provides built-in data compression capabilities through various algorithms, such as Brotli & Gzip Compression . Additionally, you can also use third-party tools like Datadog or New Relic to compress your data before sending it over the network.

III. Minimize unnecessary data transfers

Unnecessary data transfers can occur due to various reasons such as incorrect security group configurations, unoptimized database queries, or unnecessary logs. To minimize these transfers, ensure that your security groups are properly configured, optimize your database queries, and only send logs to storage when necessary.

IV. Use Content Delivery Networks (CDNs)

Content Delivery Networks (CDNs) can help distribute your content across multiple edge locations worldwide, reducing the distance your data needs to travel. This can significantly lower your data transfer costs, especially for users accessing your content from distant regions.

V. Optimize data storage

Optimizing your data storage can help reduce the amount of data being transferred, thereby lowering your data transfer costs. Consider using Amazon S3 Intelligent-Tiering Storage Class, which automatically moves infrequently accessed objects to cheaper storage classes, or Amazon Glacier, which stores data in a compressed format.

VI. Monitor data transfer usage

Monitoring your data transfer usage is essential to identify areas where you can optimize costs. AWS provides metrics like bytes transferred, number of requests, and request count by HTTP method in CloudWatch. You can use these metrics to track your data transfer usage and identify trends.

By implementing the above aws best practices, you can significantly reduce your data transfer costs and optimize your cloud spend.

8. Deleting Unused Resources

Deleting unused resources is an essential practice in optimizing AWS costs. 

Unused resources can accumulate over time due to various reasons such as:

  • Development environments: Developers may spin up resources for testing or development purposes and forget to delete them after they are no longer needed.
  • Temporary projects: Projects may require temporary resources, which are often forgotten and left running even after the project is completed.
  • Misconfigured resources: Resources may be configured incorrectly, leading to unnecessary usage. For example, a developer may accidentally leave a database instance running 24/7 instead of only during business hours.
  • Mergers and acquisitions: During mergers and acquisitions, redundant resources may be created, leading to wasted spend.

Deleting unused resources not only saves money but also helps optimize resource utilization, reduces security risks, and improves compliance.

9. Optimize Your Database Performance

Properly configuring and optimizing your databases can help reduce the number of DB instances you need, resulting in cost savings. This can be achieved through various means such as:

  • Indexing
  • Normalization, and 
  • Query optimization:

10. Use Serverless Architectures

Serverless architectures can help reduce costs by eliminating the need for provisioned instances and allowing you to pay only for the computing resources consumed by your applications. This can be achieved through the use of serverless technologies such as AWS Lambda, Azure Functions, and Google Cloud Functions.


  • Reduced costs
  • Increased scalability
  • Faster development

According to the Delloite, on average, a serverless environment takes 68% less time to provision as compared to an instancebased environment, which can equate to hundreds of dollars in savings per month per application.

11. Monitor Your Costs Regularly

Regularly monitoring your AWS costs can help you identify unexpected increases in cost and take corrective action before they become major issues. 

To avoid unexpected cost increases, it’s important to set up regular cost monitoring and alerting mechanisms. AWS offers several tools to help with cost monitoring, including AWS Cost Explorer, AWS Cost and Usage Reports, and AWS CloudWatch. These tools allow you to view detailed cost and usage data, set up alerts for when certain thresholds are met, and track trends over time.

For example, you can use AWS Cost Explorer to view detailed cost breakdowns for different regions, services, and tags. You can also use the service to simulate the cost impact of different scenarios, such as changing instance types or shutting down unused resources.
