About This Architecture

Event-driven e-commerce microservices architecture on AWS with isolated bounded contexts for Users, Catalog, Orders, Payments, Fulfillment, and Notifications. API Gateway routes client requests through WAF and CloudFront CDN to domain-specific services, each with dedicated databases and caches for data isolation and independent scaling. Order Service orchestrates cross-context workflows by invoking Payment Service, Inventory Service, and Notification Service, enabling asynchronous order fulfillment and customer communication. Shared infrastructure including CloudWatch, X-Ray, Secrets Manager, IAM, and EventBridge provides observability, security, and event-driven coupling across microservices. Fork this diagram to customize service boundaries, add message queues like SQS, or extend fulfillment workflows for your e-commerce platform.

How do you design a scalable e-commerce microservices architecture on AWS with independent services and cross-service communication?

This diagram shows a bounded-context microservices pattern where API Gateway routes requests to domain-specific services (User, Product, Order, Payment, Inventory, Notification), each with isolated databases and caches. Order Service orchestrates workflows by invoking Payment Service, Inventory Service, and Notification Service, while EventBridge and Step Functions enable asynchronous event-driven
