About This Architecture

Super Savings distributed retail architecture leverages AWS services across multiple layers: DMZ with Network Firewall and WAF, compute tier running seven ECS microservices, messaging layer with EventBridge and SQS, and data tier with Aurora, DynamoDB, and ElastiCache. Traffic flows from clients through API Gateway and Cognito authentication into a VPC spanning four private subnets, each isolating compute, messaging, data, and auxiliary services. This design demonstrates defense-in-depth security, microservice scalability, and operational resilience for high-volume retail workloads. Fork and customize this diagram on Diagrams.so to adapt subnets, add regions, or integrate additional AWS services like Lambda or Kinesis.

How do I design a scalable, secure retail system on AWS using microservices and multiple private subnets?

This diagram shows a production retail architecture spanning four private subnets: compute tier runs seven ECS microservices (Orders, Inventory, Payments, Logistics, Users, Notifications, Promotions), messaging tier uses EventBridge and SQS for asynchronous workflows, data tier combines Aurora for transactional data and DynamoDB for analytics, and a DMZ with Network Firewall and WAF protects the e
