NON_ARM_INSTANCE_TYPE_USAGE Violation Triage Guide​

Understand​

You should care because non-ARM instances may not be the most cost-effective or efficient choice for your ECS tasks compared to ARM instances.

Validate​

To ascertain the alert's accuracy, inspect the ECS Task definition through AWS Console or CLI. The data source is the ECS DescribeTaskDefinition API. Policy evaluations are conducted bi-daily. Check the evaluated Task's configuration for the runtimePlatform and requiresCompatibilities fields.

Triage​

If left unaddressed, continuation on non-ARM instances might incur higher costs without performance benefits. Remediation won't cause outages if the ECS Tasks are updated during planned maintenance windows or if they can tolerate rolling updates.

Act​

To resolve, update the task definition to use ARM-compatible instances or adjust your ECS service to specify ARM requirements.

Reflect​

If this alert was not beneficial, consider if your use case justifies the use of non-ARM instances. If so, tag ECS tasks accordingly, or adjust the policy to cater to your architectural needs.
