Event Driven Architecture
Event Driven Architecture (EDA) is a software design pattern where system components communicate by producing and consuming events—discrete messages that signify a change in state or an occurrence. This decouples components, allowing them to operate independently and asynchronously, often improving scalability and responsiveness. It is commonly used in distributed systems, microservices, and real-time applications.
Developers should learn EDA when building systems that require high scalability, loose coupling, or real-time processing, such as in microservices architectures, IoT platforms, or financial trading systems. It enables asynchronous communication, making systems more resilient to failures and easier to evolve, as components can be added or modified without direct dependencies.
