Event-driven architecture (EDA) is a software design pattern that focuses on the production, detection, consumption, and reaction to events. In this model, components communicate through events, which are significant changes in state or actions that occur within a system. This allows for a more flexible and scalable approach, as components can operate independently and respond to events as they happen. In EDA, events are typically managed by an event broker or message queue, which facilitates the flow of information between different services or applications. This architecture is commonly used in modern applications, especially in cloud computing and microservices, where responsiveness and real-time processing are essential for user experience and system performance.
