Building a cloud for computing?

Question

Cloud computing

How about the process of creating cloud services like this for games? Approximate steps?
I doubt that they use the AWS type, because games need decent video and processors, and memory.
Maybe books, guides ?
Let's say if I buy a server, can I use it as a cloud? If two?
What do you advise?
How are they set up?
How do calculations work?
How to create your own cloud?
What does a cloud make a cloud?

Answer 1

Cloud is the marketing name for SaaS. Those. on one or more servers, instead of providing a virtual machine, you provide some specific service, access to a specific application or the results of its work .... and the user does not care how exactly this application works.
Running games in the cloud is a relatively new trend, and if ordinary applications, games that do not require high responsiveness and not very dynamic scenes, can be launched using ready-made technologies (for example, the latest versions of microsoft rdp), then in a universal sense, hardware encoders connected directly to video card output (or video card support, which has been mentioned for a long time, but it was not possible to feel ready-made tools) and allow encoding video with minimal delay.
In addition to hardware problems, you will have problems with licensing the solution. Since the developers of games and programs want to receive money not from installations, but from each user, and preferably in the form of a subscription fee. Those. you will not be able to legally install a game on your servers by paying 1 copy for each server (physical hardware) and then letting hundreds of people play it a month ... more precisely, as long as you are small and inconspicuous, you will not interest anyone, but with growth you will see a very sharp jump in costs.
Yes, and from a technical point of view, it will be very difficult for you to use one installation to effectively store game profiles for several people at once and even use them at the same time. More precisely, this will not be possible for every game. I remember how I got out when I used ibik aster (two jobs from one computer) so that I could run the same game twice when its manufacturer creates barriers to this.

Answer 2

No, you cannot use one server as a cloud. You don’t understand at all (or rather, you don’t understand at all) what a cloud is
