Amazon Route 53 Application Recovery Controller zonal shift helps you quickly recover from an impairment in an Availability Zone (AZ). You can use a single action to shift application traffic away from an AZ for an Application Load Balancer or Network Load Balancer. This can help you quickly recover an application in an impaired AZ, and reduce the duration and severity of impact to the application due to events such as power outages and hardware or software failures.
In the Amazon Web Services Management Console, you can start a zonal shift by going to the Amazon Route 53 Application Recovery Controller console, or you can start a zonal shift directly from an individual load balancer resource in the Amazon Elastic Compute Cloud console. You can also use the Amazon Route 53 Application Recovery Controller API to programmatically start a zonal shift to move application traffic out of an AZ. Then, when the AZ has recovered, you can use API operations to cancel the zonal shift so that traffic returns to the AZ. You can use zonal shift with Application Load Balancers and Network Load Balancers with cross-zone load balancing turned off.
Zonal shift is now available in the Amazon Web Services China (Beijing) Region, operated by Sinnet and the Amazon Web Services China (Ningxia) Region, operated by NWCD. There is no additional charge for using zonal shift. To get started, read the Blog, visit the Home page, or read the documentation.
