Best practices for readiness check in ARC

We recommend the following best practice for readiness check in Amazon Application Recovery Controller (ARC).

Add notifications for readiness status changes

Set a rule in Amazon EventBridge to send a notification whenever a readiness check status changes, for example, from READY to NOT READY. When you receive a notification, you can investigate and address the issue, to make sure that your application and resources are ready for failover when you expect them to be.

You can set EventBridge rules to send notifications for several readiness check status changes, including for your recovery group (for your application), for a cell (such as an AWS Region), or for a readiness check for a resource set.
