Understanding Memory Underutilization

Why should I care about fixing this issue?​

Memory underutilization can lead to overprovisioning and higher costs. It's essential to optimize to ensure cost-efficiency and resource allocation.

Validate​

  • Verify the accuracy of the alert by reviewing the ECS Task's memory utilization in CloudWatch.
  • Retrieve memory utilization metrics from CloudWatch to confirm underutilization.

Triage​

  • Continuing to overprovision memory can result in wasted costs over time.
  • Reducing memory allocation should not affect other services if done with careful planning.

Act​

  • Adjust the ECS Task's memory allocation or optimize application memory usage.

Reflect​

  • If the alarm is not justifying the cost, consider adjusting the memoryUtilizationThreshold.
