Chapter 6: Using Parameters, Variables, and Template Functions

Now that you know how to define your resources, it is time to go through some of the concepts that we used but skipped, such as parameters and variables. In this chapter, we will start with parameters first, since you will need them to reuse your templates for different environments and to customize your resources.
