Virtuozzo Containers is software, which is used to generate virtual servers on a physical machine. It allows VPS accounts to be generated and controlled independently of each other, so each can have its own Operating System plus a fixed and guaranteed quantity of system resources, for example CPU time, disk space, physical memory, and the like. You can stop, start or reboot the server, to install various software packages, to perform various maintenance tasks, to set up firewall rules and even to reset the entire hosting server to its initial state using a very user-friendly online interface. You can also monitor the used and the available resources and on the active processes, in order to have an idea whether the eventual development of your sites will require a plan upgrade too. Virtuozzo gives you full control of your VPS and you'll be able to control everything conveniently, even if you don't have a lot of experience.
