I'm curious, and not antagonistically, about the size and variability of the infrastructure you're working with, on how many platforms it's running, and how many people are in charge of it.

Is this tool private or available for us to try out?

It’s small, under 50 servers running OpenBSD and Linux under a wide variety of configurations (including gpu), 6 databases, and Redis. Though the system is easily extensible to other clouds and resource types, it only needs to work on GCP right now. Been running it in prod for the past 3 or 4 years—no outages, no downtime, no surprises. Doubled infra over the holidays then scaled everything back with no issue.

The stateless approach has worked really well for us.

This is the reason we didn't get Terraform. In a windows shop the state is never the same because most people will fix it via the UI and then the state file becomes useless

sounds like a totally reasonable decision

At small sizes, this probably works reasonably well. However, as you scale, the performance will get worse and worse, and you run the risk of hitting rate limits and/or missing stuff.

So, fine for you in your personal small environment, but maybe not something suitable for Terraform in general.
