A Comprehensive Guide to AWS Cost Optimization Best Practices for Business Growth
6 min read

Introduction 

Amazon Web Services (AWS) is a leading cloud computing platform offering a wide range of services and features tailored to meet the specific needs of businesses. However, as enterprises scale their AWS infrastructure, it's crucial to implement AWS cost optimization best practices to manage expenses and maintain performance. This article will discussAWS cost optimization best practices that can help businesses reduce costs and improve performance in their AWS environment. 

AWS Cost Optimization

Right-sizing EC2 Instances 

One of the primary AWS cost optimization best practices is right-sizing EC2 instances. This involves matching the size of the instances to the workloads they support, ensuring that resources are provisioned efficiently. To achieve this:

  • Identify under-utilized instances 

Analyze utilization metrics of EC2 instances to identify those with low or idle usage. You can leverage AWS Cost Explorer, AWS Compute Optimizer, or custom monitoring tools to determine which instances can be downsized or terminated.

  • Opt for the appropriate instance families and types 

Select the appropriate instance family and type based on your workload requirements. For example, choose memory-optimized instances for memory-intensive workloads or compute-optimized instances for CPU-intensive tasks.

  • Leverage autoscaling 

Implement EC2 autoscaling to scale instances based on demand automatically. This ensures that instances are provisioned as needed, reducing the risk of over-provisioning and increasing cost efficiency.

  • Scheduling on/off times for non-production instances 

Scheduling on/off times for non-production instances, such as development, staging, or testing environments, can significantly reduce AWS costs. To implement this strategy: 

  • Analyze utilization patterns 

Examine usage patterns of non-production instances to determine the most frequently used times. Use this data to create a schedule that automatically starts and stops instances during off-hours, saving costs when the instances are not in use.

  • Use AWS Instance Scheduler 

Leverage AWS Instance Scheduler to automate the start and stop of instances based on custom schedules. This tool can help you save up to 65% of the cost of running non-production instances.

  • Utilizing Reserved Instances (RIs) and Savings Plans 

Purchasing Reserved Instances (RIs) or Savings Plans can lead to significant cost savings compared to on-demand pricing. However, it's essential to manage these commitments effectively. To do so:

  • Analyze usage patterns 

Review your usage patterns and determine if instances run long enough to justify purchasing RIs or Savings Plans. This can help you save money on unused capacity.

  • Select the appropriate RI type 

Choose between Standard or Convertible RIs based on your business needs. Standard RIs can be resold on the AWS RI Marketplace if no longer needed, while Convertible RIs allow you to change instance families and sizes.

  • Monitor RI utilization 

Monitor the utilization of RIs throughout their lifecycle to ensure they are fully utilized and deliver maximum cost savings.

  • Delete unattached EBS volumes and obsolete snapshots 

Unattached Elastic Block Store (EBS) volumes and obsolete snapshots can contribute to unnecessary AWS costs. To optimize storage costs:

  • Delete unattached EBS volumes 

Ensure that EBS volumes are deleted when instances are terminated by checking the "delete on termination" option in the AWS console. Additionally, periodically review and delete unattached EBS volumes.

  • Remove obsolete snapshots 

Regularly review and delete obsolete EBS snapshots that are no longer needed. This can help you save on storage costs and maintain a more efficient backup strategy.

  • Release unattached Elastic IP addresses 

Unattached Elastic IP addresses can incur ongoing costs. To optimize network costs:

  • Identify and release unattached Elastic IPs 

Review your AWS environment for unattached Elastic IPs and release them to avoid unnecessary charges.

  • Use AWS System Manager or AWS Console 

Leverage AWS System Manager or AWS Console to locate and release unattached Elastic IPs quickly.

  • Upgrade instances to the latest generation 

Upgrading instances to the latest generation can improve performance, functionality, and cost-effectiveness. To optimize instance costs:

  • Update existing instances 

Upgrade existing instances to the latest generation for improved performance and efficiency.

  • Downsize older generation instances 

Downsize older generation instances with borderline utilization metrics to achieve the same performance at a lower cost.

  • Optimize storage costs with tiered storage 

AWS offers multiple storage tiers with varying costs and performance characteristics. To optimize storage costs:

  • Analyze data access patterns 

Use Amazon S3 analytics tools to analyze data access patterns and determine your data's most suitable storage tier.

  • Implement lifecycle policies 

Implement lifecycle policies to automatically move infrequently accessed data to lower-cost storage tiers, such as S3 Infrequent Access or S3 Glacier.

  • Optimize data transfer costs 

Data transfer costs can have a significant impact on your AWS bill. To optimize data transfer costs:

  • Use Amazon CloudFront 

Leverage Amazon CloudFront to reduce data transfer costs when serving content to users. This Content Delivery Network (CDN) caches content at edge locations, reducing bandwidth requirements and costs.

  • Optimize data transfer within AWS services 

Ensure data transfers within AWS services, such as between EC2 and S3, are optimized to minimize costs. For example, accessing data from S3 within the same region is free of charge, while accessing data from a different region incurs costs. 

Monitor and analyze AWS costs 

Regular monitoring and analysis of AWS costs are critical to identifying cost-saving opportunities. To optimize costs:

  • Use AWS Cost Explorer 

Utilize AWS Cost Explorer to gain insights into your AWS spending, identify cost drivers, and forecast future costs.

  • Implement custom monitoring tools 

Create custom monitoring tools or leverage third-party solutions to understand your AWS costs better and identify areas for optimization.

Establish a Cloud Financial Management practice 

Implementing a Cloud Financial Management (CFM) practice can help drive a cost-conscious culture and establish cost optimization processes. A CFM practice involves:

  • Aligning financial goals 

Align financial goals with business objectives and establish guardrails to meet financial targets. 

  • Monitoring and optimizing costs 

Continuously monitor and optimize AWS costs to ensure the most efficient use of resources and maximum cost savings.

  • Leveraging AWS cost optimization tools and services 

Utilize AWS cost optimization tools and services, such as AWS Cost Explorer, AWS Budgets, and AWS Pricing Calculator, to gain insights into your spending and identify cost-saving opportunities.
