Event-Driven Microservices with Kafka & Spring Boot (Async Enterprise Integration)
Modern enterprise applications need to process large volumes of data, react to business events in real time, and scale individual services independently. Traditional synchronous REST communication is useful for many scenarios, but relying exclusively on request-response calls can create tight dependencies between microservices. Event-Driven Microservices with Apache Kafka and Spring Boot provide another approach. Instead of requiring one service to wait for another service to respond, services can publish business events to Kafka and allow interested microservices to process those events asynchronously. In this tutorial, we will explore Event-Driven Architecture (EDA) , Apache Kafka, Spring Boot, producers, consumers, topics, consumer groups, asynchronous communication, failure handling, and practical enterprise integration patterns.
