Event-Driven Architecture
Build applications that respond to events asynchronously
Intent & Description
The Event-Driven Architecture pattern builds applications that respond to events asynchronously using services like Cloud Pub/Sub, Eventarc, and Cloud Functions. This decouples producers and consumers, enables loose coupling, and provides scalability. Events represent state changes that other services can react to independently.
Real-world Use Case
Use when building applications that need to react to state changes asynchronously or when you want to decouple services through events.
