About This Architecture

Multi-region AWS e-commerce architecture spans North America (us-east-1), Europe (eu-west-1), and Asia (ap-southeast-1) with global traffic distribution via Route 53, CloudFront CDN, and Global Accelerator. Each region deploys a complete microservices stack: API Gateway behind WAF, Application Load Balancers routing to Product Catalog, Order Service, Inventory Service, Payment Service, and User Service, backed by ElastiCache Redis for session caching and Aurora PostgreSQL with cross-region read replicas. DynamoDB Global Tables replicate order data across all regions while SQS queues and SNS topics coordinate asynchronous order processing and inventory events within each region, with KMS encrypting payment data and OpenSearch indexing product catalogs for low-latency search. This architecture delivers sub-100ms response times to global customers through regional failover, active-active replication, and edge caching, demonstrating AWS best practices for high-availability e-commerce at scale.

How do I design a multi-region AWS e-commerce architecture with global database replication and sub-100ms latency?

Deploy regional stacks in us-east-1, eu-west-1, and ap-southeast-1 with Route 53 + CloudFront + Global Accelerator for traffic distribution, Aurora PostgreSQL with cross-region read replicas, DynamoDB global tables for orders, API Gateway + ALB routing to microservices (Product/Order/Inventory/Payment/User), ElastiCache Redis for sessions, SQS/SNS for async processing, and WAF for protection.
