/**
 * <p>
 * This is the API Reference Guide for the zonal shift feature of Amazon Route 53 Application Recovery Controller. This
 * guide is for developers who need detailed information about zonal shift API actions, data types, and errors.
 * </p>
 * <p>
 * Zonal shift is in preview release for Amazon Route 53 Application Recovery Controller and is subject to change.
 * </p>
 * <p>
 * Zonal shift in Route 53 ARC enables you to move traffic for a load balancer resource away from an Availability Zone.
 * Starting a zonal shift helps your application recover immediately, for example, from a developer's bad code
 * deployment or from an AWS infrastructure failure in a single Availability Zone, reducing the impact and time lost
 * from an issue in one zone.
 * </p>
 * <p>
 * Supported AWS resources are automatically registered with Route 53 ARC. Resources that are registered for zonal
 * shifts in Route 53 ARC are managed resources in Route 53 ARC. You can start a zonal shift for any managed resource in
 * your account in a Region. At this time, you can only start a zonal shift for Network Load Balancers and Application
 * Load Balancers with cross-zone load balancing turned off.
 * </p>
 * <p>
 * Zonal shifts are temporary. You must specify an expiration when you start a zonal shift, of up to three days
 * initially. If you want to still keep traffic away from an Availability Zone, you can update the zonal shift and set a
 * new expiration. You can also cancel a zonal shift, before it expires, for example, if you're ready to restore traffic
 * to the Availability Zone.
 * </p>
 * <p>
 * For more information about using zonal shift, see the <a
 * href="https://docs.aws.amazon.com/r53recovery/latest/dg/what-is-route53-recovery.html">Amazon Route 53 Application
 * Recovery Controller Developer Guide</a>.
