Description
For established businesses with multiple product lines or domains, a monolith can become a bottleneck. This architecture introduces a strong API Gateway pattern to route traffic to specialized services.
Core Components:
- API Gateway: A high-performance entry point (Kong, Tyk, or Cloud Native LB) that handles auth, rate limiting, and routing.
- Microservices: Distinct services (e.g., Billing, Users, Catalog) written in the best tool for the job.
- Container Runtime: Services run in containers (Docker/K8s) for isolation.
- Event Bus: Asynchronous communication happens via RabbitMQ, Kafka, or Cloud Pub/Sub.
Why this stack? It allows teams to work independently on different “Bounded Contexts” while presenting a unified API surface to clients.
