Well-organized Puppet manifests are easy to read; the purpose of a module should be evident in its name. The purpose of a node should be defined in a single class. This single class should include all classes that are required to perform that purpose. Craig Dunn wrote a post about such a classification system, which he dubbed "roles and profiles" (http://www. craigdunn.org/2012/05/239/). In this model, roles are the single purpose of a node; a node may only have one role, a role may contain more than one profile, and a profile contains all the resources related to a single service. In this example, we will create a web server role that uses several profiles.
