1.简介
Event-Driven Architecture (EDA) is a technology-enhanced approach to designing, developing, and operating complex systems. EDA has emerged as an increasingly popular solution for managing complexity in large-scale enterprise systems, where the need for near real-time responses to external events such as sensor readings or user actions arises. This article presents a comprehensive survey of EDA concepts, taxonomies, and architectures with a focus on their key features, strengths, weaknesses, and applicability. We also provide detailed explanations and illustrative examples of some important event processing models and tools used in EDA applications. Finally, we highlight future trends and challenges that require further researc
