About This Architecture

Multi-AZ e-commerce system leveraging Route 53, CloudFront, WAF, and ALB for global content delivery and DDoS protection. ECS microservices (Catalog, Cart, Order, Payment) run across two availability zones with RDS Primary/Standby, DynamoDB Sessions, and ElastiCache Redis for data persistence and caching. Asynchronous order processing via SQS triggers Lambda notifications through SNS, while Cognito handles authentication and CloudWatch aggregates logs to S3. This architecture demonstrates high availability, fault tolerance, and separation of concerns across presentation, application, and data tiers.

How do I design a highly available e-commerce system on AWS with multi-AZ failover and microservices?

This diagram shows a production e-commerce architecture spanning two availability zones with ECS microservices (Catalog, Cart, Order, Payment), RDS Primary/Standby for relational data, DynamoDB for sessions, and ElastiCache Redis for caching. Route 53 provides DNS failover, CloudFront accelerates static assets, WAF blocks attacks, and SQS/Lambda handle asynchronous order notifications—ensuring hig
