We all have a postal address where presents from Santa may end up (if he mails them, of course) for Christmas. Message channels resemble such addresses where the messages will be sent or received. Producers and consumers do not talk to each other directly but communicate via these channels. The decoupling of the sender and receiver components is primarily achieved by using channels. Channels represent pipes in our pipes and filters pattern. You can create a complex integration solution consisting of channels and endpoints.
This chapter mainly focuses on configuring and using these channels.
