Triage Guide: Non-ARM Instance Type in Use

Understand​

This alert indicates that your ElastiCache cluster is running on a non-ARM (e.g., Intel or AMD) instance type, which may not be as cost-effective or performant as an ARM-based instance type.

Validate​

Confirm this alert by reviewing the instance types in use by your ElastiCache clusters in the AWS Management Console or by using the AWS CLI/SDK to describe your cache clusters. The policy runs daily.

Triage​

Non-ARM instances could result in higher costs without performance benefits. Unaddressed, the operating costs will continue to accrue. Remediation should not cause outages if performed carefully during maintenance windows.

Act​

To fix this alert, you may need to plan for the migration of your ElastiCache clusters to ARM-based instance types.

Reflect​

If this alert does not apply to your use case, for example, if the application requires a specific non-ARM instance type, consider marking the resource as an exception by using AWS resource tags.
