Question
A company needs to implement disaster recovery (DR) for its application. The application’s production environment consists of Amazon EC2 instances in an Auto Scaling group and an Amazon RDS database that has three read replicas. The DR environment uses a single EC2 instance in an Auto Scaling group and one cross-Region read replica. The company uses Amazon Route 53 for DNS resolution. A SysOps administrator must automate the DR process. However, the SysOps administrator must maintain manual control over the final failover step of updating DNS records. Which solution will meet these requirements with the LEAST downtime?

Explanation
An AWS Systems Manager Automation runbook can orchestrate the multi-step DR actions - scale the ASG, add replicas, and promote/fail over the DB - quickly and repeatably. You keep manual control by triggering the final Route 53 update only after the runbook finishes preparing the DR site. This yields minimal downtime with controlled DNS cutover.
