Event-Driven Microservices
ELI5 — The Vibe Check
Event-driven microservices communicate by publishing events instead of calling each other directly. 'Hey, an order was placed!' and everyone who cares reacts independently. It's like a group chat where services post updates and others respond at their own pace.
Real Talk
A microservices architecture where services communicate primarily through asynchronous events rather than synchronous API calls. Services publish domain events to a message broker (Kafka, RabbitMQ, EventBridge), and interested services subscribe and react. This pattern enables loose coupling, independent scaling, and resilience to individual service failures.
When You'll Hear This
"Event-driven microservices let the shipping service go down without affecting order placement." / "We moved from REST-based microservices to event-driven and our system became much more resilient."
