Event-Driven Microservices Diagram

Event-Driven Microservices

This event-driven microservices diagram separates catalog, order and inventory concerns behind an API gateway. Each service can publish activity to an event bus rather than requiring every downstream function to call it directly. An analytics service receives order information for reporting or operational analysis. The diagram is a compact way to discuss service boundaries and asynchronous communication without representing deployment details, topics or individual message schemas.

よくある質問

What is event-driven microservices architecture?

Services publish events about state changes so other services can react asynchronously.

Why use an event bus?

It decouples event producers from the services that consume their events.

Should every service use events?

No. Use events for asynchronous state changes; direct requests can still suit immediate queries or commands.
