About This Architecture

Warm Standby multi-region DR architecture spanning us-east-1 (active) and eu-west-2 (standby) with automated failover via Step Functions and sub-1-minute RPO. User traffic flows through Route 53, CloudFront, WAF, Cognito, and API Gateway to multi-AZ ECS Fargate clusters backed by Aurora Global Database, EFS, and ECR with continuous cross-region replication. Hybrid connectivity via Direct Connect primary, secondary, and VPN fallback routes traffic through Transit Gateway to on-premises systems. This architecture demonstrates enterprise-grade DR best practices: health-validated cutover, quarterly FIS testing, KMS multi-region encryption, and automated failover with 15–30 minute RTO. Fork this diagram on Diagrams.so to customize VPC CIDRs, AZ counts, or failover thresholds for your organization's RPO/RTO targets.

How do I design a warm standby disaster recovery architecture on AWS with multi-region failover and sub-1-minute RPO?

This diagram shows a warm standby DR setup spanning us-east-1 (active) and eu-west-2 (standby) using Aurora Global Database for <1-minute replication lag, ECS Fargate with minimal standby capacity, and automated Step Functions failover with health validation. Cross-region replication covers ECR, EFS, Secrets Manager, KMS, and S3, while hybrid connectivity via Direct Connect and VPN ensures on-prem
