Description

Currently, Cloud Custodian does not support AWS DMS replication instances (aws.dms-instance) as a resource type. Due to this limitation, we are unable to implement governance and cost optimization policies for DMS replication instances.

Use Case

Customer requirement to identify idle DMS replication instances:

Instances with no associated replication tasks

Instances that are unused/idle for >30 days

Include these in recommendations for cleanup or cost optimization

At present, this use case cannot be achieved since the resource type is not supported in Custodian.

Expected Outcome

Add support for aws.dms-instance in Cloud Custodian

Enable filtering based on:

Instance attributes (ARN, status, creation time, etc.)

Association with replication tasks

Support standard actions like:

Notify
