What is Virtual Private Server ?

Virtual Private Servers can be a big help when setting up multiple servers.
Pretty much, what this allows you to do is take one server and divided it up into multiple servers.

Some people even refer to Virtual Private Servers as Virtual Dedicated Servers.
The process allows you to bridge the gap between a shared web hosting service and the dedicated hosting service.

That means that you are going to be able to run a different operating system on each server, and that means that
you can reboot each server independently. So now you are asking, “So what does all that mean?”

The good thing about all this is that it means that you can run a new system on a server that you know has flaws and risks,
without endangering the rest of the servers. You will be able test out different types of software that
may be known for security risks without having to worry about all the other servers going down.

This can come in very handy when you have more than one server on a network. As you can see, the Virtual Private Server is making a big impact.
