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.
