Support for Infrastructure as Code (terraform, etc...)

So it dawned on me, that say you wanted to represent not just your application, but the external dependencies for it (so, the miraculous things that happen in AWS, GCP, etc...), I wasn't entirely sure how to represent this! I'm opening this issue as more so a collection of ideas, no concrete feeling that I'll come out of it with YES THIS IS HOW, but more so to see how people think about it?

This could be slightly duplicative of the intent of something like terraform, too! Terraform is meant to manage your IaC, and it creates files that describe what it plans to do, or state, (terraform plans, terraform state, etc...)

Mostly curious as to others thoughts around this. How would YOU describe them?
