Event-Driven Architecture

Components communicating through produced and consumed events.

How it works

Components publish events to a broker and others react asynchronously, decoupling producers and consumers and enabling scalable pipelines.

Where it is used

Order processing, notifications.

Common pitfall

Harder to trace flows and ensure ordering and idempotency.

Where it fits in the course

Event-Driven Architecture is topic 36 of 50 in Software Engineering, rated Advanced. It follows Monolith vs Microservices. The next topic is CQRS and Event Sourcing.
