AWS Compute Optimizer is a source of rightsizing and idle-resource recommendations. It is not EC2-only: the supported-resource documentation lists multiple resource types, including EBS and supported database configurations. Availability and metric requirements differ by resource.
Review recommendations in context
For EC2, review the observed utilization, lookback period, performance risk, migration effort, and estimated cost impact. Confirm that the data includes representative peaks, scheduled jobs, and failover requirements. Memory visibility depends on supported metric collection; do not infer memory headroom from CPU alone.
A recommendation is an input to an engineering decision. Check architecture compatibility, dependencies, availability requirements, and owner approval before changing an instance.
Implement and verify
A direct change to an EBS-backed instance's type generally involves stopping and restarting it. For a managed fleet, plan a replacement rollout with appropriate capacity and health checks. Neither approach guarantees an interruption-free change by itself.
Keep a rollback path. After implementation, check application health, resource metrics, and actual billing. Separate the estimated opportunity from savings measured after the change.
Include idle resources
Compute Optimizer also provides idle-resource recommendations. Review the supported resource and criteria rather than assuming that idle detection requires another product. A resource used only for a rare event or recovery may need context beyond an observed quiet period.
Check the pricing scope
Consult Compute Optimizer pricing. Standard recommendations and optional paid features have different terms; do not describe every option as free. The same distinction applies to Cost Explorer's console, API, and data options.
PointFive OS in the workflow
PointFive OS helps connect infrastructure context with investigation, optimization, and customer-defined automation across connected sources. Discovery can use read-only access. Infrastructure changes require customer-authorized write access and approval before execution. Prompt remediation follows the engineer's selected IDE and deployment workflow.
Evaluate the additional context and operating workflow your team needs. A native recommendation does not automatically eliminate the need for investigation, and a third-party platform does not automatically produce better results.

Frequently asked questions
Is Compute Optimizer limited to EC2?
No. AWS documents several supported resource types, with resource-specific requirements.
Can it identify idle resources?
Yes, for supported resources and conditions. Validate the finding against the resource's intended purpose before acting.
Does a recommendation prove savings?
No. It is an estimate to evaluate; confirm the result against application behavior and billing after implementation.
