Event-Driven Microservice Integration

Welcome to Event-Driven Microservice Integration! In this lesson, we'll learn how microservices can communicate asynchronously using events.

An event-driven architecture (EDA) is a software design pattern where services communicate by producing and consuming "events." These events are records of something that happened.

This approach helps create highly decoupled, scalable, and resilient systems.

Why choose event-driven communication over direct API calls (synchronous)?

• Decoupling: Services don't need to know about each other's existence. They only care about events.
• Resilience: If a consuming service is down, the events are stored and processed later, preventing cascading failures.
• Scalability: Producers can publish events without waiting for consumers, and multiple consumers can process events in parallel.
