Event-driven architecture in cloud computing: Principles, patterns, and practical applications

This article presents a comprehensive examination of Event-Driven Architecture (EDA) as a foundational pattern for modern cloud computing systems. It explores the core components of EDA—event producers, event brokers, and event consumers—while analyzing how these elements interact to create responsive, decoupled, and scalable applications. Through detailed examination of implementation patterns across multiple domains including e-commerce, financial services, and IoT applications, the article demonstrates EDA's versatility and effectiveness in addressing contemporary computing challenges. The theoretical underpinnings of EDA are contrasted with traditional request-response models, highlighting the paradigm shift toward reactive systems. Particular attention is given to cloud-native implementations, serverless computing models, and the integration challenges organizations face during adoption. The article concludes with an analysis of emerging trends and future directions, positioning EDA as an essential architectural approach for systems requiring real-time responsiveness, scalability, and resilience in increasingly distributed computing environments.
