startZonalShift
You start a zonal shift to temporarily move load balancer traffic away from an Availability Zone in an Amazon Web Services Region, to help your application recover immediately, for example, from a developer's bad code deployment or from an Amazon Web Services infrastructure failure in a single Availability Zone. You can start a zonal shift in ARC only for managed resources in your Amazon Web Services account in an Amazon Web Services Region. Resources are automatically registered with ARC by Amazon Web Services services.
Amazon Application Recovery Controller currently supports enabling the following resources for zonal shift and zonal autoshift:
When you start a zonal shift, traffic for the resource is no longer routed to the Availability Zone. The zonal shift is created immediately in ARC. However, it can take a short time, typically up to a few minutes, for existing, in-progress connections in the Availability Zone to complete.
For more information, see Zonal shift in the Amazon Application Recovery Controller Developer Guide.
