Virtuozzo Containers is software, that's used to make virtual servers on a physical server. It allows VPS accounts to be set up and controlled independently of one another, so each one can have its unique OS in addition to a fixed and guaranteed volume of system resources, for example CPU time, disk space, physical memory, and the like. You will be able to start, stop or restart the server, to set up a variety of software packages, to perform various maintenance tasks, to create firewall rules and even to reboot the entire server to its initial state employing a very intuitive web interface. You may also keep track of the used and the available system resources and on the active processes, in order to have an idea when the eventual development of your web sites will require a package upgrade too. Virtuozzo provides you with full control of your VPS and you can manage everything easily, even when you don't have much experience.
