API for AWS ARC - Zonal Shift¶
|ABAP SDK "TLA"||
The "TLA" is a Three Letter Abbreviation that appears in ABAP class names, data dictionary
objects and other ABAP objects throughout the AWS SDK for SAP ABAP. The TLA for AWS ARC - Zonal Shift is
This TLA helps squeeze ABAP objects into the 30-character length limit of the ABAP data dictionary.
To install the AWS SDK for SAP ABAP, import the Core transport, along with the transport for the ARC Zonal Shift module and other API modules you are interested in. A few modules are included in the Core transport itself. For more information, see the Developer Guide guide.
About The Service¶
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.
Zonal shift is in preview release for Amazon Route 53 Application Recovery Controller and is subject to change.
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.
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.
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.
For more information about using zonal shift, see the Amazon Route 53 Application Recovery Controller Developer Guide.
Using the SDK¶
In your code, create a client using the SDK module for AWS ARC - Zonal Shift, which is created with
In this example we will assume you have configured
an SDK profile in transaction
DATA(go_session) = /aws1/cl_rt_session_aws=>create( 'ZFINANCE' ). DATA(go_azs) = /aws1/cl_azs_factory=>create( go_session ).

Creates an object of type
TYPE REF TO
TYPE REF TO
/AWS1/IF_AZSrepresents the ABAP client for the ARC Zonal Shift service, representing each operation as a method call. For more information see the API Page page.
DATA(lo_config) = DATA(go_azs)->get_config( ).
Paginators for AWS ARC - Zonal Shift can be created via
get_paginator() which returns a paginator object of type
/AWS1/IF_AZS_PAGINATOR. The operation method that is being paginated is called using the paginator object, which accepts any necessary parameters to provide to the underlying API operation. This returns an iterator object which can be used to iterate over paginated results using
