Event-Driven Architecture (EDA)

Choreography

Orchestration

Events between microservices

Events inside microservices

A software architecture paradigm promoting the production, detection, consumption of, and reaction to events.

Advantages of EDA

• Asynchronous - This allows resources to move freely to the next task once their unit of work is complete, without worrying about what happened before or will happen next.
• Loose Coupling - When using events, services operate independently, without knowledge of other services, including their implementation details and transport protocol
• Easy scaling of individual services thanks to decoupling
• Recovery support through “event replay”
