AWS Cost Optimization

Cost Optimization

Cost optimization involves continuously refining your AWS environment to reduce spending while maintaining performance. This includes rightsizing resources, using appropriate pricing models, and leveraging AWS tools to identify savings opportunities.

Cost Optimization Strategies

Here are practical ways to optimize costs across common AWS services.

Amazon EC2 Optimization

One way to optimize cost with Amazon EC2 instances is to rightsize your resources.

This means that you analyze and adjust your resources to meet the needs of your workload.

Services such as AWS Compute Optimizer can help rightsize your compute resources.

Spot Instances

Using Spot Instances can help optimize for cost.

Spot Instances work well for workloads that are tolerant to interruptions.

Spot Instances use spare Amazon EC2 capacity for a significant discount compared to On-Demand instances.

Auto Scaling

Another way to help optimize cost with compute resources is auto scaling.

When demand drops, AWS Auto Scaling will automatically remove any excess resource capacity, so you avoid overspending.

Application load balancing also helps distribute traffic across EC2 instances.

Amazon RDS Optimization

Rightsizing is an important piece of cost optimization in your Amazon RDS instances.

Amazon RDS can scale storage using storage autoscaling which prevents over- or underprovisioning.

Read Replicas

Read replicas scale capacity horizontally, meaning your resources won't need to scale up into a larger instance.

Instead of scaling the primary instance, read replicas are used to store data and can be used for heavy read workloads which reduces the strain on the primary instance.

Caching

Using something like Amazon ElastiCache for caching can also reduce the load on your primary instance and optimize for cost.

Amazon S3 Optimization

Using the right storage class is key to optimizing cost in the cloud.

Storage Classes

• S3 Glacier Deep Archive: Low-cost storage tier ideal for data that is accessed once or twice a year
• S3 Intelligent-Tiering: Great choice for data with unknown or changing access patterns

VPC Endpoints

You can use VPC endpoints to help optimize for cost as well.

Using VPC endpoints for Amazon S3 access can help reduce data transfer costs.
