As we have seen, when components are named generically, it is less likely that they will need to be renamed at a later point. However, when a component is named explicitly, it is more likely that a user who is unfamiliar with the SLS tree will understand what it is trying to accomplish.

A good naming convention strives to strike a balance between the oil and water of generic versus explicit. To borrow from the food and chemistry worlds, a good naming convention is the emulsifier that binds everything in a recipe or formula together.

Generic names

Before starting out with an SLS tree, let's try to plan out as many of the primal components as possible. As an example, a modern infrastructure may reasonably include the following components:

  • A load balancer

  • A database server

  • A web server

  • A firewall

  • An application code base

  • An e-mail server

We will start with names that reflect these primal components before moving...
