What is event-driven architecture and how does it work?

Event-driven architecture (EDA) is a software design pattern where the system responds to events or changes in state. It allows for asynchronous communication between components, making systems more scalable and flexible.

What are the main components of event-driven architecture?

The main components include event producers, event consumers, event channels, and event processing systems. Producers generate events, consumers react to them, and channels facilitate communication.

Can you give me an example of where EDA is used?

Sure! EDA is commonly used in applications like online shopping platforms, where user actions (like adding items to a cart) trigger events that update inventory and user interfaces.

What are the benefits of using event-driven architecture?

Benefits include improved scalability, better responsiveness, and the ability to handle high volumes of events efficiently. It also promotes loose coupling between components.
