Cloud service for PS3, PS4, Xbox games?

Question

Sony PlayStation

Is there any cloud service for games on Sonya or Xbox?
The Internet is littered with clouds with built-in Nvidia, but this is all available on a PC.
I want to go through some exclusives, but of course I don’t want to buy separately.

Answer 1

PS Now is for Sony. Official
There is not everything, but a lot.
