A microservices architecture diagram shows how an application is split into small, independently deployable services. It centers on an API gateway routing client requests to discrete services like auth, orders, and payments, with a message broker for async events and each service owning its own database. The diagram exposes service boundaries and communication paths at a glance.
Backend architects, engineering leads, and cloud teams use it to plan decomposition, document service ownership, and review scaling and resilience. It is a staple of design docs, architecture decision records, and onboarding for distributed systems built on Kubernetes or serverless platforms.
Great for
- Architecture design docs
- Decomposition planning
- Engineering onboarding
- Architecture decision records
- System design interviews
Frequently asked questions
What is microservices architecture?+
Microservices architecture structures an application as a set of small, independently deployable services that each own a business capability and communicate over the network.
What are the components of a microservices architecture?+
Typical components include an API gateway, individual services, a message broker for async events, per-service databases, and shared infrastructure like caching and service discovery.
Why use an API gateway in microservices?+
An API gateway gives clients a single entry point, handling routing, authentication, rate limiting, and aggregation so services stay focused on business logic.
How do microservices communicate?+
Services communicate synchronously over HTTP/gRPC through the gateway and asynchronously through a message broker like Kafka or RabbitMQ for event-driven workflows.
