AWS Compute Optimizer
- What it is
- Machine-learning-based right-sizing recommendations from actual utilization history.
- Covers EC2 instances, Auto Scaling groups, EBS volumes, AWS Lambda functions, ECS on Fargate, RDS, and commercial software licenses.
- What it produces
- Over-provisioned, under-provisioned, or optimized classification per resource.
- A specific recommended instance type with projected cost savings and performance risk.
- Not to be confused with
- AWS Trusted Advisor — flags idle and underutilized resources with simple thresholds. Compute Optimizer models workload patterns and names the better instance type.
- AWS Cost Explorer — spend analysis; its own right-sizing recommendations are powered by Compute Optimizer.
- Ties to
- Right-sizing and the Cost Optimization pillar of the AWS Well-Architected Framework.
