Communication

Event-Driven Architecture (EDA)

Description

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

Where to use

  • Decoupling microservices.
    • \n
  • Real-time applications.
    • \n
  • Scalable systems.

Real World Example

When a user updates their profile, a 'ProfileUpdated' event is emitted. The Search Service, Email Service, and Analytics Service all independently react to this event.

Code Example

# Code Concept for Event-Driven Architecture (EDA)\n# This pattern is architectural.\n\nclass Service:\n    def execute(self):\n        # Implementation logic\n        pass
