Answer
Event-driven architecture means services communicate via published events instead of synchronous calls.
This improves loose coupling, scalability, and resilience. Events can be domain events, integration events, or system events.
Quick Answer
In event-driven microservices, services communicate by publishing events to a broker (Kafka, RabbitMQ). No direct service-to-service calls. Producer publishes "UserRegistered", consumer services independently react. This decouples services temporally and spatially - they don't need to be running at the same time or know each other's addresses.
