Event-Driven Microservices

What is it?

An architecture where independent services communicate through a message broker instead of calling each other directly.

The Problem it Solves

Services that call each other directly stay coupled, even after being split apart.

How the Architecture Works

1. API Gateway — routes traffic to the service layer.
2. Services — independent, each handling its own part of the domain.
3. Message broker — services publish and consume events instead of calling each other.
4. Persistence layer — each service owns its own database.
