AWS::ARCZonalShift::ZonalAutoshiftConfiguration PracticeRunConfiguration

A practice run configuration for a resource includes the Amazon CloudWatch alarms that you've specified for a practice run, as well as any blocked dates or blocked windows for the practice run.

When a resource has a practice run configuation, Route 53 ARC starts weekly zonal shifts for the resource, to shift traffic away from an Availability Zone. Weekly practice runs help you to make sure that your application can continue to operate normally with the loss of one Availability Zone.

You can update or delete a practice run configuration. When you delete a practice run configuration, zonal autoshift is disabled for the resource. A practice run configuration is required when zonal autoshift is enabled.

Syntax

To declare this entity in your Amazon CloudFormation template, use the following syntax:
