ShopEase's multi-AZ AWS architecture spans two availability zones with Route 53, CloudFront, WAF, and Shield protecting a VPC housing ALBs, EC2 web servers, and ECS microservices across isolated subnets. Data flows through RDS Aurora, ElastiCache, DynamoDB, and DocumentDB with read replicas in AZ-2, while Lambda functions handle order confirmation, returns processing, inventory sync, and reporting triggered by EventBridge and SQS. This design demonstrates high availability, fault isolation, and event-driven processing—critical for retail systems handling online orders, POS integration, and warehouse operations simultaneously. Fork and customize this diagram on Diagrams.so to adapt subnet sizing, add additional Lambda workflows, or modify database replication strategies. The management subnet isolates CloudWatch, X-Ray, CloudTrail, and Secrets Manager, enforcing least-privilege access and audit compliance across production workloads.
