Amazon EKS now supports Amazon Application Recovery Controller (ARC)
Amazon Elastic Kubernetes Service (Amazon EKS) now supports Amazon Application Recovery Controller (ARC) zonal shift and zonal autoshift. ARC helps you manage and coordinate recovery for your applications across AWS Regions and Availability Zones (AZs). With EKS support for ARC zonal shift and zonal autoshift, you can better maintain Kubernetes application availability by automating the process of shifting in-cluster network traffic away from an impaired AZ.
Customers increasingly deploy highly available applications in Amazon EKS across multiple AZs to eliminate a single point of failure. If you’re running multi-AZ applications in EKS, you can now quickly shift application traffic away from an impaired AZ in your cluster. With zonal shift, you can temporarily mitigate issues and incidents by triggering a shift and redirecting in-cluster network traffic to a healthy AZ. For a fully automated experience, you can authorize AWS to manage this shift on your behalf using zonal autoshift. With zonal autoshift, you can configure practice runs to test that your cluster environment functions as expected with one less AZ.
To get started, you can enable zonal shift using the Amazon EKS Console, the AWS CLI, CloudFormation or eksctl. Once enabled, you can manage zonal shifts or zonal autoshifts using the ARC Console, the AWS CLI, or the Zonal Shift and Zonal Autoshift APIs. EKS support for ARC zonal shift and zonal autoshift is available in all commercial AWS Regions, excluding the AWS GovCloud (US) Regions. To get started, visit our documentation.
