In the previous section, the modules we discussed are what are known as component modules since they cover single implementations.

But different users are not interested in how a node is configured; instead, they are interested in what it does. An application specialist, for example, would care that, for their application, Tomcat and MySQL were installed, not how it was configured. A project manager would care that they got a server that met a business need but not what technical stacks were used. The project manager may also see each implementation as unique, but there will often be a lot of similarities, such as various technology stacks being used across multiple applications using Apache or Java with variations...
