Just to add, I've written a bit about this at http://bit.ly/puppetworkflows2and you might want to take a look Profiles are TECHNOLOGY-specific, so a profile for wordpress, and one for drupal, and one for java, and etc... Roles are BUSINESS LOGIC-specific, so a role for your cluster nodes, or a role for your application servers, and etc (however you refer to your machines internally). This allows you to swap out profiles (technology-specific components) in the event that different roles require different technology components.
