Amazon Application Recovery Controller zonal shift and zonal autoshift extends support for two new multi-AZ resources

Amazon Application Recovery Controller (ARC) zonal shift and zonal autoshift have expanded their capabilities and now support Amazon Elastic Kubernetes Service (Amazon EKS) and Network Load Balancers (NLB) with cross-zone configuration enabled. ARC zonal shift helps customers quickly recover an unhealthy application in an Availability Zone (AZ), and reduce the duration and severity of impact to the application due to events such as power outages and hardware or software failures. ARC zonal autoshift safely and automatically shifts an application’s traffic away from an AZ when AWS identifies a potential failure affecting that AZ.

All NLB customers can now shift traffic away from an AZ in the event of a failure. Zonal shift works with NLB by blocking all traffic to targets in an impaired AZ and removing the zonal IP from DNS responses while it is active. You can enable NLBs for zonal shift using the NLB console or API.

Amazon EKS customers can now shift traffic away from an AZ in the event of a failure. Zonal shift works with Amazon EKS by shifting in-cluster traffic to healthy AZs and ensuring Pods aren’t scheduled in the impaired AZ. You can enable EKS clusters for zonal shift using the EKS console or API.

You can start a zonal shift or enable Zonal autoshift in the ARC console for EKS and NLB resources. There is no additional charge for using zonal shift or zonal autoshift. See the AWS Regional Services List for the most up-to-date availability information.
