Event-driven architecture

What is Event-driven architecture?

Event-driven architecture (EDA) is a design pattern where components communicate by producing and consuming events rather than calling each other directly. This decoupled approach enables systems to scale efficiently and react to real-time changes. EDA is commonly used in distributed systems, microservices, IoT platforms, and applications that require high responsiveness. It improves flexibility, reduces system dependencies, and supports asynchronous workflows.
