About This Architecture

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.

How do you design a multi-AZ AWS architecture for a retail platform handling online orders, POS integration, and warehouse operations?

ShopEase's architecture spans two AZs with Route 53 and CloudFront for global distribution, ALBs and Auto Scaling Groups for web tier resilience, ECS and Lambda microservices for order and inventory processing, and RDS Aurora with standby replicas plus DynamoDB and DocumentDB for data durability. EventBridge and SQS decouple order events, while Redshift and Athena enable analytics on the S3 data l
