Is it possible to make a mini cloud (vps) on a separate hdd in windows 7?

Question

Network administration

Hello colleagues!)
So, the question is:
There is an excellent working (one might say powerful) computer, in fact, I work on it, play, etc.
I accidentally found a clean 400 GB hdd and now I’m thinking what to do useful on it, so that I have practice and don’t kill time in vain. So I thought about the practice of creating a cloud)
Tell me?
If this is impossible and just stupid - give me advice on what to do with it)))

Answer 1

Install virtualbox, it will have a distribution kit with Linux, there will be a "VPS" on the local computer.
"mini cloud"
This concept is now used in dozens of meanings, who is in what much, specify what is meant.
