Amazon Route 53 Application Recovery Controller zonal autoshift available in AWS GovCloud (US) Regions

Amazon Route 53 Application Recovery Controller (Route 53 ARC) zonal autoshift is now generally available in the AWS GovCloud (US-East and US-West) Regions. AWS customers and AWS Partners who operate in the AWS GovCloud (US) Regions can now use zonal autoshift, a feature you can enable to safely and automatically shift an application’s traffic away from an Availability Zone (AZ) when AWS identifies a potential failure affecting that AZ. For failures such as power and networking outages, zonal autoshift improves the availability of your application by shifting your application traffic away from an affected AZ to healthy AZs.

To get started, you can enable zonal autoshift for Application Load Balancer and Network Load Balancer, with cross-zone configuration disabled, using the console, SDK or CLI, or an Amazon CloudFormation template. Once enabled, Amazon will automatically shift application traffic away from an affected AZ, and shift it back after the failure is resolved. Zonal autoshift includes practice runs, a feature that proactively tests if your application has sufficient capacity in each AZ to operate normally even after shifting away from an affected AZ. You configure practice runs to automatically apply zonal shifts, which regularly check if your application can tolerate losing capacity in an AZ.
