// Code generated by smithy-go-codegen DO NOT EDIT.
// Package arczonalshift provides the API client, operations, and parameter types
// for AWS ARC - Zonal Shift.
//
// Welcome to the Zonal Shift API Reference Guide for Amazon Route 53 Application
// Recovery Controller (Route 53 ARC).
//
// You can start a zonal shift to move traffic for a load balancer resource away
// from an Availability Zone to help your application recover quickly from an
// impairment in an Availability Zone. For example, you can recover your
// application from a developer's bad code deployment or from an Amazon Web
// Services infrastructure failure in a single Availability Zone.
//
// You can also configure zonal autoshift for a load balancer resource. Zonal
// autoshift is a capability in Route 53 ARC where Amazon Web Services shifts away
// application resource traffic from an Availability Zone, on your behalf, to help
// reduce your time to recovery during events. Amazon Web Services shifts away
// traffic for resources that are enabled for zonal autoshift whenever Amazon Web
// Services determines that there's an issue in the Availability Zone that could
// potentially affect customers.
//
// To ensure that zonal autoshift is safe for your application, you must also
// configure practice runs when you enable zonal autoshift for a resource. Practice
// runs start weekly zonal shifts for a resource, to shift traffic for the resource
// out of an Availability Zone. Practice runs make sure, on a regular basis, that
// you have enough capacity in all the Availability Zones in an Amazon Web Services
// Region for your application to continue to operate normally when traffic for a
// resource is shifted away from one Availability Zone.
//
// You must prescale resource capacity in all Availability Zones in the Region
// where your application is deployed, before you configure practice runs or enable
// zonal autoshift for a resource. You should not rely on scaling on demand when an
// autoshift or practice run starts.
//
// For more information about using zonal shift and zonal autoshift, see the [Amazon Route 53 Application Recovery Controller Developer Guide].
