AWS Cost Optimization: Tips and Tricks for Saving Money

Are you an AWS user who is getting frustrated with the rising cost of cloud services? Are you tired of paying for unused resources and hidden fees? Don't worry, you are not alone, and there is a way out of this dilemma. AWS cost optimization is the answer to your problem.

In this article, we will provide you with a comprehensive guide to AWS cost optimization techniques that will help you reduce your cloud-based expenses significantly. We will discuss different cost optimization strategies, including how to choose the right AWS pricing model, how to identify and eliminate idle resources, how to use AWS Cost Explorer and other tools, and much more.


AWS is the most popular cloud platform on the market, thanks to its scalability, flexibility, and reliability. But like any other cloud service provider, AWS charges you based on how much you use its services. AWS cost optimization, therefore, is about finding ways to optimize your usage and reduce expenses while keeping your infrastructure running at optimal capacity.

AWS offers a wide range of services, and the way these services are priced varies depending on the specific service you are using, the region you are in, and your usage patterns. For example, AWS EC2 instances can be charged by the hour, by the second, or through a reserved instance model. Similarly, AWS S3 storage can be priced based on storage class, storage duration, data retrieval fees, etc.

To optimize your AWS costs, you need to understand these pricing models and choose the one that best suits your needs. Additionally, you need to have a good sense of your workload to be able to identify idle resources and eliminate them.

AWS Cost Optimization Techniques

Choose the Right AWS Pricing Model

Choosing the right pricing model is one of the most important steps in AWS cost optimization. There are several pricing models available, and choosing the wrong one can lead to unnecessary expenses.


AWS On-Demand instances allow you to pay by the hour with no upfront cost or long-term commitment. This model is ideal for users who need to scale their infrastructure up or down quickly and do not want to invest in a long-term contract. However, On-Demand instances are the most expensive option.

Reserved Instances

AWS Reserved Instances require upfront payment, but offer a significant discount over the On-Demand pricing model. Reserved Instances are ideal for users who have a stable workload and can commit to a one or three-year contract. Purchasing a Reserved Instance can save you up to 75% compared to the On-Demand model.

Spot Instances

AWS Spot Instances are the cheapest instances available but come with no SLA or availability guarantee. Spot Instances allow you to bid on unused EC2 capacity and can save you up to 90% compared to the On-Demand pricing model. However, the downside of Spot Instances is that they can be interrupted at any time, and you may need to restart your workload on another instance.

Savings Plan

AWS Savings Plans provide savings of up to 72% on your AWS usage in exchange for a commitment to a consistent amount of usage over a one or three-year term. Savings Plans offer flexibility since they can be used on any EC2 or Fargate instance, regardless of family, size, region, or operating system.

Identify Idle Resources

Idle resources are one of the biggest culprits behind unused expenses in the AWS cloud. Idle resources are resources that are not being used or underutilized, yet you are still paying for them. Identifying and eliminating idle resources is a crucial step in AWS cost optimization strategy.

Rightsize Your Instances

Rightsizing your instances means choosing the instance size that best fits your workload requirements, rather than over-provisioning or under-provisioning. Over-provisioning means using an instance size that is more powerful than what you actually need, resulting in higher costs. Under-provisioning means using an instance size that is not powerful enough to handle your workload, resulting in performance issues or higher costs.

Schedule Shutdowns

Another way to reduce your AWS cost is to schedule and automate instance shutdowns when they are not needed. You can use AWS Lambda, AWS CloudWatch, or other tools to schedule shutdowns during non-peak hours, weekends, or any time when your workload is not operational.

Use Auto Scaling

AWS Auto Scaling allows you to maintain optimal capacity and performance by automatically scaling up or down your resources based on the demand. By using Auto Scaling, you can ensure that you are only paying for the resources you need at any given time. Auto Scaling can be used with EC2 instances, RDS instances, and other AWS services.

Use AWS Cost Explorer

AWS Cost Explorer is a powerful tool that allows you to visualize and analyze your AWS usage and costs. With Cost Explorer, you can track and optimize your costs over time by creating custom reports, setting budget alerts, and tracking cost and usage trends. Cost Explorer provides detailed insights into your costs, including usage by service, region, and utilization type.

Use AWS Trusted Advisor

AWS Trusted Advisor is a tool that provides recommendations on best practices and cost optimization techniques based on your usage patterns. Trusted Advisor provides guidance on various areas, such as cost optimization, security, fault tolerance, and performance. Trusted Advisor can help you reduce costs by identifying unused resources, optimizing instance types, and much more.

Use AWS S3 Intelligent-Tiering

AWS S3 Intelligent-Tiering is a storage class that automatically moves objects between two access tiers based on changing access patterns and data usage. Intelligent-Tiering can optimize costs by matching data access patterns to the most cost-effective tier, resulting in up to 40% savings compared to the standard S3 storage class.

Use AWS Reserved Capacity

AWS also provides Reserved Capacity for their RDS, DynamoDB and ElastiCache services. Amazon RDS Reserved Capacity allows you to save up to 75% on your database costs by committing to using a specific instance type in a particular availability zone for a one or three-year term. DynamoDB and ElastiCache offer similar savings with Reserved Capacity.


AWS cost optimization is a continuous process that requires consistent monitoring and optimization. By choosing the right pricing model, identifying and eliminating idle resources, using AWS Cost Explorer and other tools, you can significantly reduce your AWS cloud costs.

Reducing your AWS cost can result in significant savings, freeing up resources to invest in other areas of your business. AWS provides various tools and resources to help you optimize your costs, and we hope this guide has provided you with the necessary information to get started.

Remember, AWS cost optimization is an ongoing process, and you should regularly review and adjust your usage patterns to keep your costs under control. Happy cloud computing!
