%% @doc 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:
%% https://docs.aws.amazon.com/r53recovery/latest/dg/what-is-route53-recovery.html.

%% @doc 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 Route 53 ARC only for managed
%% resources in your Amazon Web Services account in an Amazon Web Services
%% Region. Resources are automatically registered with Route 53 ARC
%% by Amazon Web Services services.
%%
%% 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.
%%
%% 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 Route 53 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:
%% https://docs.aws.amazon.com/r53recovery/latest/dg/arc-zonal-shift.html
%% in the Amazon Route 53 Application Recovery Controller Developer Guide.
