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 from users through Route 53 to CloudFront, then WAF-protected ALBs routing to ECS Fargate services across two availability zones per region. Application tier connects to Aurora PostgreSQL (writer/reader replicas) and ElastiCache Redis clusters with cross-region replication, while IAM task roles enforce least-privilege access to databases and S3. Route 53 health checks continuously monitor both regions, enabling automatic failover to maintain availability during regional outages. This architecture demonstrates enterprise-grade resilience, compliance with multi-AZ redundancy, and optimized latency via global content delivery.
