Multi-region AWS architecture with active-passive failover across US-EAST-1 and EU-WEST-1 for disaster recovery. Route 53 routes traffic through CloudFront with WAF to a three-tier VPC spanning three availability zones, using ECS Fargate for auto-scaling web and API services, Aurora with read replicas, and ElastiCache Redis sharding. This pattern demonstrates enterprise-grade resilience with cross-region Aurora replication, DynamoDB Global Tables, and a warm standby DR region with minimal capacity.

The CI/CD pipeline with CodePipeline, CodeBuild, and CodeDeploy enables blue-green deployments to ECR-hosted containers.
