Seven Best Practices for AWS Cost Optimization

Right-size Your EC2 Instances

EC2 instances are the virtual servers that power your AWS applications. By selecting the right size for your workload, you can optimize your resources and save money.

Many organizations make the mistake of selecting larger EC2 instances than they need, resulting in wasted resources and unnecessary costs. By right-sizing your EC2 instances, you can Optimize EC2 instances to reduce wastage and costs.

To right-size your EC2 instances, you must carefully evaluate your workload. Then only you can select the instance type and size that best matches your requirements. This involves considering factors such as CPU, memory, network performance, storage capacity, type of application running, and the workload generated. 

Once you have selected the right size for your EC2 instances, you can further optimize your resources by using tools such as AWS Auto Scaling and AWS Spot Instances. These tools automatically adjust the number of instances in your fleet based on demand and offer significant cost savings for workloads that can tolerate interruptions, respectively.

Choose the Appropriate AWS Region

AWS has a global network of regions and availability zones, and selecting the right region can significantly impact your application's performance and cost.

Choosing the right region involves considering factors such as the location of your users, the proximity to other AWS services you are using, and the regulatory requirements of your industry. 

Selecting the region closest to your users can reduce latency and improve the user experience while reducing data transfer costs.

In addition, choosing the appropriate AWS region can also help you optimize your costs. Different regions have different pricing for AWS services, and selecting a region with lower costs can result in significant savings over time.

To help you choose the right AWS region for your workloads, AWS provides tools such as the AWS Global Infrastructure map and the AWS Region Table, which allow you to compare the pricing and features of different regions and make an informed decision.

Turn Off Unused Instances By Creating Schedules 

One common issue many organizations face with their AWS environments is leaving instances running when not in use. This can lead to wasted resources and unnecessary costs. However, by creating schedules to turn off unused instances, you can save money and reduce waste.

AWS offers Instance Scheduler and Systems Manager Automation to schedule instance start and stop times based on usage.

By creating schedules to turn off unused instances, you can ensure that your resources are only active when needed, reducing costs and increasing efficiency. This practice is particularly useful for non-production environments, such as development or testing environments, where instances are often left outside working hours.

Use or Sell Under-Utilized Reserved Instances

One way to save money on your AWS costs is by using Reserved Instances (RI) to reduce your hourly usage rates. However, you may still pay more than necessary if you are not using your RIs to their full potential. This is where the practice of using or selling under-utilized Reserved Instances comes in.

By monitoring your usage patterns and matching them to the most appropriate RI type, you can ensure that you are getting the maximum cost savings from your RIs. 

However, if you have RIs that are not being used or are being used less than expected, you can use them for other workloads or sell them on the AWS Reserved Instance Marketplace.

The AWS RI Marketplace allows you to sell your unused or under-utilized RIs to other AWS users, recouping some of your costs and potentially saving money for others. This is a great way to optimize AWS costs and maximize savings.

Leverage Compute Savings Plans to Reduce Compute Costs

Compute Savings Plans are a flexible, low-cost pricing model for EC2 instances and Fargate containers. With this model, you can save up to 66% of your compute costs over On-Demand rates. 

Compute Savings Plans require a commitment to use a specific amount of compute usage for one or three years. In return, you get a discount on the on-demand rates for the instance families and regions you choose. 

Good part? it includes no upfront costs or minimum usage requirements.

Identify and Delete Orphaned Snapshots

AWS snapshots are a great way to back up your data, but they can also be a source of unnecessary costs if they are not properly managed. An orphaned snapshot is a snapshot that is no longer associated with an active EBS volume. These snapshots continue in your account, taking up space and adding to your storage costs.

To identify orphaned snapshots, you can use the AWS Management Console, AWS CLI, or a third-party tool like CloudCheckr. Once you have identified the orphaned snapshots, you can delete them to free up space and reduce costs.

Use AWS Enterprise Billing Console to Charge Back Amazon Cost To Internal Users

When an organization has multiple departments and teams using AWS resources, tracking the use of each team can be challenging. This can be solved by using the AWS Enterprise Billing Console to allocate and chargeback AWS costs to internal users.

With the AWS EBC, you can create cost allocation reports that show the usage and cost of each team. You can use these reports to allocate costs to individual teams based on their usage and charge them accordingly.

This helps you track the usage and cost of each team and department. Doing so encourages them to optimize their usage and cost, leading to better cost management across the organization.

For Controlling Cost 

  • Plan a budget to manage your AWS resource spending.

  • Review your costs with the Cost and Usage Report in the AWS Console.

  • Utilize AWS Trusted Advisor to identify unused resources and estimate costs.

For Optimizing Compute Instances 

  • Choose reserved instances for predictable and consistent workloads, and use on-demand instances for unpredictable or variable workloads.

  • Consider using spot instances for workloads that don't require high reliability, as they can be significantly cheaper.

  • Schedule instances to run only when needed or during business hours to save costs. You can use AWS Instance Scheduler or other tools to automate this.

  • Choose the appropriate service for your workload, whether EC2 or another service that meets your requirements.

  • Purchase reserved instances for a reasonable period, and don't keep them longer than necessary if you don't need them.

  • Use the latest instance types, as they often offer better performance or efficiency at a lower price.

For Optimizing Storage And Multiple Other Resources 

  • Store your production files in S3 and use S3 Smart Tiering to move them between storage tiers based on activity.

  • Use S3 Glacier to archive infrequently used data and Glacier Deep Archive to back up your long-term archived data.

  • To avoid orphaned EBS volumes, check the "Delete on Termination" checkbox when creating EC2 instances.

  • In most cases, keep EBS snapshots for only a few weeks, and delete them as new ones are created.

  • Terminate unneeded resources such as database volumes and Elastic IPs that are not in use.
