// Package arczonalshift provides the client and types for making API
// requests to AWS ARC - Zonal Shift.
//
// Welcome to the API Reference Guide for zonal shift and zonal autoshift in
// 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 supported load balancer resources.
// Zonal autoshift is a capability in Route 53 ARC where you authorize Amazon
// Web Services to shift away application resource traffic from an Availability
// Zone during events, on your behalf, to help reduce your time to recovery.
// Amazon Web Services starts an autoshift when internal telemetry indicates
// that there is an Availability Zone impairment that could potentially impact
// customers.
//
// To help make sure 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 away from an Availability Zone. Practice runs help you to
// 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.
//
// Before you configure practice runs or enable zonal autoshift, we strongly
// recommend that you prescale your application resource capacity in all Availability
// Zones in the Region where your application resources are deployed. You should
// not rely on scaling on demand when an autoshift or practice run starts. Zonal
// autoshift, including practice runs, works independently, and does not wait
// for auto scaling actions to complete. Relying on auto scaling, instead of
// pre-scaling, can result in loss of availability.
//
// If you use auto scaling to handle regular cycles of traffic, we strongly
// recommend that you configure the minimum capacity of your auto scaling to
// continue operating normally with the loss of an Availability Zone.
//
// Be aware that Route 53 ARC does not inspect the health of individual resources.
// Amazon Web Services only starts an autoshift when Amazon Web Services telemetry
// detects that there is an Availability Zone impairment that could potentially
// impact customers. In some cases, resources might be shifted away that are
// not experiencing impact.

// # Using the Client
//
// To contact AWS ARC - Zonal Shift with the SDK use the New function to create
// a new service client. With that client you can make API requests to the service.
// These clients are safe to use concurrently.
