We covered roles in this chapter. Roles provide a way to classify patterns of use in your in-

ce.
In the next and final chapter of this topic, we'll cover environments, which provide a differ-
ent code of abstraction—a way to map your organization's app deployment workflow to a set
of server configurations and cookbook versions.
