There is a new announcement every half year or so by one firm or the other. But we've never managed to get beyond getting a sample, and not for a lack of trying. Numbers just aren't available, models change extremely fast, producers go bancrupt. Maybe it will get better as soon as one of the big server producers starts with Arms?
Edit: to clarify, I mean on AWS, not from the Amazon store.
Also, don't really like vendor lock-in.
I thought it would be horrible, but after a brief adjustment period it turned out to be okay-ish for my current work.

You could build your own rack and send it to them, but the more common model is renting preconfigured servers on a monthly or annual basis with them swapping out broken hardware as needed etc.
Cloud computing can save on administrative costs, but there is a huge world between building everything in house and AWS.
You can definitely save money this way but it rarely ends up being as much as touted - double digit percentages, not whole multiples - unless you’re really bandwidth intensive.
