Overview
Spring Cloud Stream is a framework for building highly scalable event-driven microservices connected with shared messaging systems. Spring applications use Spring Cloud Stream libraries to bind to a messaging middleware, using a middleware-neutral API. The application uses input and output channel channel abstractions injected into it by Spring Cloud Stream runtime. Channels are connected to brokers through middleware-specific binder implementations.
Spring Cloud Stream builds upon Spring Boot to create standalone production-grade applications. Spring Initializr lists Spring Cloud Stream under "Cloud Messaging"

Channel
An input channel is an object present in the memory of a Spring application whose implementation is transparently created by Spring Cloud Stream and injected int the application. The application uses input channel to receive messages. Similarly, an output channel is also an object created and injected by Spring Cloud Stream into the application. Application sends messages via output channels.
