Event Driven Architecture
What is Event Driven Architecture? Discover what is event driven architecture, its core components, benefits, and real-world examples in this comprehensive guide. Event-driven architecture (EDA) is a software design pattern where systems communicate by producing and reacting to events, such as a user placing an order or a sensor detecting a temperature change. Instead of repeatedly checking for updates (request-driven), EDA provides instant notifications when an event occurs, enabling a responsive and asynchronous flow of information. Understanding Event Driven Architecture in Practice To understand EDA's distinction, compare it to a traditional request-response system where one service directly calls another and waits for a reply, creating dependencies. If the called service is slow or unresponsive, the process halts. In contrast, event-driven architecture broadcasts events like UserLoggedIn or PaymentProcessed, allowing other services to listen and react independently, without t...
