Super Savings retail microservices architecture spans five AWS subnets orchestrating orders, inventory, payments, and logistics through ECS-based services. EventBridge and Step Functions implement the Saga pattern for distributed transactions, while Aurora, DynamoDB, and ElastiCache handle persistence across public, compute, messaging, and data layers. CloudFront, WAF, Shield, and Cognito secure the entry layer; CloudWatch, X-Ray, and GuardDuty provide observability and threat detection.
