Test failover between AWS regions using Route 53.
- Setup:
- Deploy a simple web application in two regions (
us-east-1 and us-west-2).
- Configure RDS with cross-region replication.
- Enable Route 53 latency-based routing.
- Steps:
- Simulate an outage by stopping the primary region’s application.
- Observe Route 53 failover directing traffic to the secondary region.
- Validate database replication by updating content in the secondary region and verifying consistency.
- Outcome:
- Traffic shifts seamlessly to the secondary region.
- Database updates reflect properly in the secondary environment.
