An application runs in a single AWS Region on an Amazon EKS cluster and uses an Amazon Aurora MySQL cluster. Container images are built by AWS CodeBuild and stored in Amazon ECR. The company must replicate both the container images and the database state to a second Region with the least operational overhead. Which approach meets these needs?

The correct option leverages native AWS features for replication with minimal operational overhead. ECR cross-Region replication automatically copies container images to a specified target Region, eliminating manual steps or custom Lambda functions. Aurora Global Database provides a fully managed, low-latency, and highly available solution for cross-Region database replication, simplifying failover and read replica management. The other options involve more complex or less efficient methods: S3 CRR is not directly applicable to ECR images (ECR uses S3 but manages its own replication). Manually triggering Lambda functions for ECR replication adds operational overhead. Modifying CodeBuild to push to multiple ECRs increases build complexity. Binary log replication for Aurora MySQL is a manual process compared to Aurora Global Database.
