A company hosts an ecommerce site using EC2, ALB, and DynamoDB in one AWS Region. The site uses a custom domain in Route 53. The company wants toreplicate the stack to a second Region for disaster rec

CloudFormation allows programmatic and consistent deployment of the entire application stack (EC2, ALB, DynamoDB with Global Tables) to the second region, while Route 53 latency-based routing efficiently directs global users to the closest healthy region for faster access and implicitly supports disaster recovery.

Manually recreating infrastructure is error-prone, time-consuming, and not repeatable, and weighted routing is not optimal for directing users to the lowest latency endpoint for global access.

Replicating only data (S3 and DynamoDB) is insufficient; the application's compute resources (EC2, ALB) are also part of the 'stack' and must be present in the second region for full disaster recovery.

Introducing Elastic Beanstalk is a re-platforming effort not requested for simply replicating the existing EC2/ALB stack, and DynamoDB Global Tables are a more managed solution for cross-region data replication than streams for 'faster access'.
