This idea was actually the first idea for Mighty before I pivoted a few months ago.
macOS can only be run on Apple hardware btw. That also makes the cost structure for this kind of business complex.
Good luck!
Currently using Windows 10 Servers on user-dedicated EC2 instances, so costs are bundled in, but once I get into a multi-tenant setup and cost optimization I'll see what I can work out with Microsoft.
Serverside MacOS is a nut I'm not trying to crack at the moment. Too many lawsuits of people trying to monetize Apple products.
Lastly: Mighty is an excellent move. The macro shift toward cloud-native makes browser-based tools more pervasive. You're well-positioned with Chrome, mate.
Good luck, but note that you are competing with Microsoft (who offers Azure Virtual Desktops), so they aren't likely to want to work out a favorable (for you) deal.
Ouch, that sounds expensive! I would imagine the economics of this will be a tough sell compared to one's own laptop or desktop?
