<p>Spring Cloud Bus links nodes of a distributed system with a lightweight message broker. This can then be used to broadcast state changes (e.g. configuration changes) or other management instructions. AMQP and Kafka broker implementations are included with the project. Alternatively, any <a href="https://spring.io/projects/spring-cloud-stream">Spring Cloud Stream</a> binder found on the classpath will work out of the box as a transport.</p>
