When dealing with a large fleet of IoT devices, one of the most needed features is to segment them into several groups.
Barracks approach on segmentation is to allow you to have both exclusives and non-exclusives groups. We call the exclusives groups: channels.
Channels are the best way to build up a beta segment to your fleet so you can test new features, gather metrics, improve your product and test it again before sending it out in the bush.
By default, we give you three channels to play with: alpha, beta and production.
Production is the default channel. This means that any devices enrolls in Production by default.
