Multi-region e-commerce platform spanning AWS us-east-1 and eu-west-1 with Route 53 failover routing, CloudFront CDN, and WAF protection. Traffic flows through ALBs to ECS Fargate tasks across two availability zones per region, with ElastiCache Redis for session/product caching and Aurora PostgreSQL (writer in primary, reader in secondary) for transactional data. This architecture delivers sub-100ms latency globally, automatic regional failover, and compliance with data residency requirements for European customers.
