There are other services like this, mostly for gamers. Vagon is $1.29/hour, plus $8/month.
There's no technical problem doing this, but it's an expensive service to provide. The pricing is usually too high to get a market. NVidia's GEForce Now and Google's Stadia are running at a loss for promotional reasons. The game industry's reaction to Stadia is that almost everybody who considered supporting it expects Google will cancel that service.
Is Vagon reselling AWS, or do they have their own data center?
