About This Architecture

Production-grade microservices architecture on AWS with five containerized services (Order, User, Inventory, Notification, Payment) deployed on ECS and fronted by API Gateway with WAF and Shield protection. Services communicate asynchronously via Amazon MSK Kafka and EventBridge, persist to dedicated RDS databases, and emit telemetry through CloudWatch and X-Ray for unified observability. IAM, Cognito, Secrets Manager, and KMS enforce least-privilege access and encryption across the platform.

How do I design a production microservices architecture on AWS with async messaging, security, and observability?

This diagram shows a battle-tested AWS microservices pattern: five containerized services on ECS communicate via Amazon MSK Kafka and EventBridge, each backed by dedicated RDS databases. Security is layered with WAF, Shield, Cognito, IAM, and Secrets Manager with KMS encryption, while CloudWatch and X-Ray provide end-to-end observability and tracing.
