A detailed AWS multi-region disaster recovery architecture demonstrates how to automatically shift traffic during a regional outage. The design uses Amazon Route 53 for DNS failover, Application Load Balancers in two regions (ap-south-1 and us-east-1), and Auto Scaling Groups with pre-built AMIs for rapid EC2 instance recovery.

The architecture protects stateful data via a cross-region RDS read replica, which can be promoted during a failure. EFS provides shared storage with backup strategies. This setup targets a recovery time objective of 1-2 minutes and a recovery point objective of seconds, simulating enterprise-grade resilience without manual intervention.

This project is a practical blueprint for cloud engineers, addressing the critical need for uptime in production systems. It moves beyond theory by testing real failure scenarios, from stopping an instance to promoting a database replica. The hands-on documentation offers a tangible framework for building and validating high-availability infrastructure on AWS.
