Ubuntu and several (hundreds) of users, is it possible to implement?

Question

linux

Essence of the question.
What is the best way to implement the following scheme? It is necessary that when registering on the site, the user receives conditional 500MB-1GB on the server, has access to the console and, for example, has the opportunity to install AMP.
Is it possible to create users within one system and each user initially has a clean ubuntu and already puts a stack of packages on it to work.
Or will it be necessary to create a new folder with the ubuntu package for each user on the server and get the same VPS only for 1GB?
Tell me where to dig and what you can read on this topic. I will be grateful!
Thanks :)
