Event - Driven Architecture: Building Responsive and Scalable Systems

Venkata Naga Sai Kiran Challa

Abstract: Event-Driven Architecture EDA leverages event notifications to efficiently handle billions of actions and interactions within complex systems, such as those involving millions of users. By employing event producers, consumers, brokers, and streams, EDA enables asynchronous and scalable processing. This approach decouples system components, allowing them to evolve independently while maintaining system reliability through standardized event schemas and robust event delivery mechanisms. Implementations using technologies like Apache Kafka and Apache Flink facilitate real-time processing and fault tolerance. Integration with machine learning enhances predictive maintenance and decision-making, while blockchain ensures data integrity and automation. The use of EDA in smart city management showcases its potential to optimize operations, enhance resource utilization, and improve quality of life.
