Virtuozzo Containers is a software solution, that's used to make virtual servers on a physical machine. It allows VPS accounts to be set up and controlled separately of one another, so each of them can have its own OS as well as a fixed and guaranteed volume of resources, including CPU time, disk space, physical memory, and so on. You will be able to stop, start or reboot the server, to set up many different software packages, to do numerous maintenance tasks, to set up firewall rules and even to reset the entire server to its initial state through a very intuitive web interface. You may also keep track of the used and the available system resources and on the active processes, so as to have an idea whether the eventual growth of your web sites will require a package upgrade too. Virtuozzo gives you complete control over your VPS and you're able to manage everything without difficulty, even if you do not have much experience.
