Spring Cloud Stream is a framework built on top of Spring Boot and Spring Integration that is designed to build event-driven microservices communicating via one or more shared messaging systems.
The core Spring Cloud Stream component is called “Binder,” a crucial abstraction that’s already been implemented for the most common messaging systems (e.g. Apache Kafka, Kafka Streams, Google PubSub, RabbitMQ, Azure EventHub, and Azure ServiceBus).
