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)
# This pattern is architectural.

class Service:
    def execute(self):
        # Implementation logic
        pass
