How we delivered it
Conducted a post-incident review of the 6-hour outage to identify all single points of failure in the existing architecture.
Designed a multi-region active-passive architecture with automated Route 53 health checks and failover policies.
Implemented database replication with sub-5-second RPO using AWS Aurora Global Database across two regions.
Built a chaos engineering test suite that simulates region failures, database outages, and traffic spikes to validate DR procedures quarterly.
Delivered a DR runbook and trained the client's engineering team on failover procedures, achieving a 90-second RTO in final testing.
What we built
Designed and implemented a multi-region active-passive DR architecture on AWS with automated failover under 90 seconds.
