GOG, the gaming storefront owned by CD Projekt, is getting into cloud gaming by teaming up with Amazon Luna. Since the Luna cloud service streams games from Amazon's cloud servers, you'll be able to access the titles you've purchased from the store across any compatible device you own, including PCs, Macs, Android and iOS mobile devices, as well as smart TVs and Fire tablets. That is, so long as those devices are installed with the Luna app and you're connected to the internet. You'll also be able to use any Luna-compatible devices and controllers, such as Xbox One's and PS4's, to play your games.
