For more details, you may refer to the Spring Cloud Stream specifications.

The important thing for us is an ability to use multiple binders in a single application. You can even mix different implementations, for example, RabbitMQ with Kafka. Spring Cloud Stream relies on Spring Boot's auto-configuration in the binding process. The implementation available on the classpath is used automatically.
