Amazon ECR announces cross region replication of images

Amazon Elastic Container Registry (Amazon ECR) now supports cross region replication of images in private repositories, enabling developers to easily copy container images across multiple AWS accounts and regions with a single push to a source repository. Storing images in-region to your infrastructure helps applications start up faster as image download time is reduced due to lower latency, and removes cross region downloads that helps with region isolation. Geographically dispersed images also helps you meet backup and disaster recovery requirements for your application. By creating a simple way to reliably replicate images across regions, Amazon ECR now makes it even easier to run highly available applications in AWS.
