Multi-region AWS architecture deploys ECS Fargate microservices (API, Auth, Worker) across us-east-1 and us-west-2 with automated failover. Route 53 health checks direct CloudFront traffic to active Application Load Balancers, while RDS PostgreSQL replicates from primary to read replica and ElastiCache Redis clusters maintain session state in both regions. SQS queues handle background jobs, S3 stores file uploads, and CodePipeline with CodeBuild deploys containers to ECR across regions, with CloudWatch, X-Ray, and Secrets Manager providing observability and secrets management. This architecture demonstrates AWS best practices for geographic redundancy, minimizing RTO/RPO for mission-critical workloads requiring 99.99% availability.
