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.
