Virtuozzo Containers is software, that is used to create virtual servers on a physical server. It allows VPS accounts to be generated and managed independently of each other, so each one can have its unique Operating System in addition to a fixed and guaranteed amount of system resources, for example CPU time, disk space, physical memory, and the like. You can stop, start or reboot the server, to install many different software packages, to perform various maintenance tasks, to set up firewall rules and even to reboot the entire hosting server to its initial state employing a very intuitive web interface. In addition, you can monitor the used and the available system resources and on the active processes, in order to have an idea whether the eventual development of your web sites will require a package upgrade too. Virtuozzo will give you full control of your VPS and you will be able to control everything easily, even when you do not have much experience.
