Cloud game streaming services - what are the prospects?

Question

Cloud computing

There is one Russian service playkey , there are references to other foreign services that Sony bought and closed.
From the latest news - home streaming from NVidia (Shield), Playstation NOW and Steam Home, but this only applies to local streaming when a powerful "server" machine is already available.
Interested in analogues of the playkey service (to play by receiving a video stream from the server without installations and other things) - is there something similar with more recent games? If not, why not? What are the pitfalls?

Answer 1

One of the main pitfalls is the channel width from the server to the client. It is necessary to calculate and transfer about 30-60 720p images per second over the Internet, depending on client input

Answer 2

"to play by receiving a video stream from the server without settings and other things", I don’t even want to give analogues, read about RemoteFX

Answer 3

Sea problems:
Home streaming is still all right, but Internet streaming has little chance in the coming years.

Answer 4

liquid sky. This idea is the future, IMHO.
