“Virtual Private Server”.
Three simple words that kind of hide a more complex system. Let me dive into some more details.
Think of it as the ” Virtual Box” of web hosting. If you don’t know what Virtual Box is, it’s basically a software which allows you tu run multiple Operation Systems ( OS ) on one computer. Now if we go back in the world of Web Hosting, VPS is basically “many virtual servers on one physical server”, with each virtual server being completely independant, and acting as a dedicated server by itself.
Now of course, when buying a VPS, you’re actually buying one whole physical server – you don’t actually share it with other people, unlike shared hosting. The downside to this alternative is that VPS are more expensive than the more restricted shared hosting, ranging from 20 to 60 dollars per month.
Needless to say that one website running on a VPS will have poorer performances than one website running on a dedicated server. So if you’re actually building one website and you’re expecting alot of trafic on it, go for dedicated if you can ( it is costy ).
Now on the other hand, if you’re the kind of guy that builds networks with alot of NDDs, and are searching for a simple way to manage all of that, the VPS is as of now the better choice ( combined with cPanel or Plesk ). So go for it. You won’t regret it.
