Guidelines for the Application of Event Driven Architecture in Micro Services with High Volume of Data

Abstract

Event-Driven architecture (EDA) has proven itself as a transformative strategy within microservices, celebrated for its role in enabling scalable, responsive, and decoupled interactions among system components. This paper draws on insights from diverse domains such as e-commerce, healthcare, IoT, and data processing to showcase how EDA can revolutionize system agility and responsiveness, particularly under high communication loads and real-time processing demands. We underscore EDA’s effectiveness in optimizing critical processes like order management, payment processing, and real-time anomaly detection through 13 case studies. These enhancements not only boost operational efficiency but also foster more informed decision-making. Moreover, the burgeoning interest in applying EDA to complex systems that necessitate dynamic adaptation to environmental changes, such as climate risk management and intelligent manufacturing, underscores its potential. However, adopting EDA is not without its challenges, particularly in state management, consistency, and testing, which necessitate further exploration. This paper contributes to the discourse on EDA by reviewing its current state, challenges, and future directions, offering a comprehensive perspective on its role and potential in modern software architecture.
