I'm in the funny position of having to test products in the cloud at a company that is really skittish about putting any of its own stuff in the cloud. I looked at AWS Outposts, but determined that it likely wouldn't pass muster with our policies. It was also really expensive, and it was only available for rent, not purchase.

I then did an experiment with the Azure Stack Development Kit. It was limited to a weird ghetto of outdated VM images, and had to be rebooted every few weeks. I did not proceed with Stack Hub.

If GCP wasn't a distant third place, I might give this thing a try, but it's probably really expensive just for testing.

The long term solution is going to be chipping away at our policies, but I was disappointed that I couldn't find a usable on-prem cloud solution.
