Memory Underutilization Triage Guide​

  1. Understand

Memory overprovisioning leads to higher costs with no performance benefit.

  1. Validate

Check metrics against AWS CloudWatch data. Retrieve data from the CloudWatch console. This policy runs on a schedule.

  1. Triage

Costs can accumulate if unaddressed. No impact on other services during remediation.

  1. Act

Optimize cluster size according to actual memory needs or apply autoscaling.

  1. Reflect

If the alarm recurs, consider revising the memory utilization threshold or examine workload patterns.
