About This Architecture

Multi-region three-tier disaster recovery architecture spanning AWS us-east-1 primary and us-east-2 standby regions with Route 53 DNS failover, Transit Gateway cross-region connectivity, and synchronized Aurora PostgreSQL replicas. Traffic flows from clients through Route 53 to primary ALBs in us-east-1 across two availability zones, passing through WAF before reaching ECS Fargate services in private subnets that consume S3 and SQS events. Data persists in Aurora PostgreSQL primary with continuous replication to DR replica, while S3 buckets sync across regions and CloudWatch plus Datadog monitor both environments. This architecture demonstrates active-passive failover with RPO/RTO optimization through cross-region database replication, asynchronous queue processing, and standby compute resources ready for activation. Fork and customize this diagram on Diagrams.so to adjust region pairs, add additional tiers, or modify failover policies for your compliance requirements.

How do I design a multi-region disaster recovery architecture on AWS with automatic failover and data replication?

This diagram shows a production-ready multi-region DR setup using Route 53 for DNS failover between us-east-1 primary and us-east-2 standby regions, Aurora PostgreSQL synchronous replication for RPO optimization, and ECS Fargate services in private subnets consuming events from S3 and SQS. Transit Gateway connects regions while CloudWatch and Datadog provide unified monitoring across both environm
