Multi-region e-commerce platform leveraging Route 53 failover routing, CloudFront CDN, and AWS Shield for global resilience and DDoS protection. Traffic flows through WAF and ALBs to containerized ECS Fargate microservices (API, Cart, Order) across us-east-1 and eu-west-1 regions, with ElastiCache Redis and Aurora PostgreSQL replicas ensuring low-latency reads and automatic failover. This architecture demonstrates active-passive multi-region design with cross-AZ redundancy, meeting high-availability and disaster-recovery requirements for mission-critical retail workloads. Fork and customize this diagram on Diagrams.so to adapt CIDR blocks, add additional regions, or integrate Lambda for serverless components. Consider implementing Aurora global database for read-only secondaries in eu-west-1 to reduce replication latency and improve consistency.
