Introduction

Event-driven architecture (EDA) is a design paradigm where services communicate through events rather than direct API calls. This approach enables loose coupling, horizontal scalability, and resilient system design.

Core Concepts

• •Event Producers — Services that emit domain events
• •Event Brokers — Middleware that routes and stores events
• •Event Consumers — Services that react to events asynchronously
• •Event Sourcing — Using events as the single source of truth
• •CQRS Pattern — Separating read and write operations
