We all know the benefits of infrastructure as code - version control, reusability, shareability, documentation, and so on. Another popular notion is that of code as data, by which code can be introspected, modified, and used for decision making. Combining the two ideas, the natural implication is that infrastructure is also data, and can be similarly introspected, modified, and used for decision making. In other words, we can do math on infrastructure. We'll look at some interesting ways this data can be filtered, combined, and applied to achieve results which would be difficult to describe directly in code.
