Infrastructure as Code, Patterns and Practices

3 Patterns for infrastructure modules

This chapter covers

• Grouping infrastructure resources into composable modules based on function
• Building infrastructure modules with software development design patterns
• Applying module patterns to common infrastructure use cases

In the preceding chapter, I covered the fundamental practices for infrastructure as code. Even though I knew the fundamental practices, my first Python automation script grouped code into one file with messy functions. Years later, I learned software design patterns. They provided a standard set of patterns that made it easier for me to change the script and hand it over to another teammate for maintenance.

In the following two chapters, I show how to apply design patterns to IaC ...
