About This Architecture

Multi-region AWS architecture spans us-east-1 and us-west-2 with automated failover orchestrated by Route 53 latency-based routing and health checks. Primary region deploys ECS Fargate services across three availability zones behind an Application Load Balancer, with RDS PostgreSQL Multi-AZ primary and ElastiCache Redis for session state. CloudFront and WAF provide global edge security while RDS read replicas in us-west-2 enable sub-minute RTO during regional failures. Solutions architects can fork this diagram on Diagrams.so to model disaster recovery strategies, customize VPC CIDR blocks, or add cross-region VPC peering for hybrid failover patterns.

People also ask

How do I design a multi-region AWS architecture with automated failover for high availability?

Deploy ECS Fargate services across three availability zones in a primary region with RDS PostgreSQL Multi-AZ and ElastiCache Redis. Configure Route 53 health checks for latency-based routing to a secondary region with promotable RDS read replicas and replicated ECS services, enabling sub-minute RTO during regional outages.
