Amazon Application Recovery Controller (ARC) in AWS GovCloud (US)
How Amazon Application Recovery Controller (ARC) differs for AWS GovCloud (US)
The AWS GovCloud (US-West) implementation of ARC is unique in the following way:
-
The routing control, and readiness check features of the ARC service are not available in AWS GovCloud (US-West).
Zonal Shift
You can use ARC zonal shift to quickly isolate and recover from single Availability Zone (AZ) impairments. Zonal shift temporarily shifts traffic for a supported resource away from an impaired AZ to healthy AZs in the same AWS Region. Starting a zonal shift helps your application recover quickly, for example, from a developer’s bad code deployment or from an AWS impairment in a single AZ. Shifting traffic away from the impaired AZ reduces the impact for clients who are using your application in the impaired AZ.
You can start a zonal shift for any supported resource in your account in an AWS Region. Zonal shifts are manual and temporary. When you start a zonal shift, you must specify an (extendable) expiration of up to three days.
Region Switch
You can use Region switch in ARC to orchestrate large-scale, complex recovery tasks for your application resources across AWS accounts, to help ensure business continuity and reduce operational overhead. Region switch provides a centralized and observable solution that you can perform manually, or automate by using Amazon CloudWatch alarm triggers. If an AWS Region becomes impaired, you can execute the plans that you create by using Region switch to fail over or switch your resources to another Region. This ensures that your application can continue to operate, running in a healthy AWS Region.
