Question

A company operates a web application on AWS. Its web tier uses an Amazon Elastic Container Service (Amazon ECS) deployment with the Fargate launch type behind an Application Load Balancer (ALB) and Amazon Route 53. The application uses an Amazon Keyspaces (for Apache Cassandra) database. The company keeps container images in Amazon Elastic Container Registry (Amazon ECR). New image versions are pushed on a regular basis. The company must implement a multi-Region recovery strategy with automatic failover to a secondary Region. Which solution meets these requirements?

Accepted Answer

B. Configure Amazon ECR private image replication to a new ECR private registry in the secondary Region. Configure Amazon Keyspaces multi-Region replication to the secondary Region. Create an ALB and a new Fargate service with the desired count set to 1 in the secondary Region. Create new Route 53 DNS records that use a failover routing policy.
