Virtuozzo Containers is software, that is used to generate virtual servers on a physical server. It allows VPS accounts to be set up and managed independently of each other, so each one can have its own Operating System in addition to a fixed and ensured amount of system resources, for example CPU time, disk space, physical memory, and the like. You'll be able to start, stop or restart the server, to set up various software packages, to do numerous maintenance tasks, to create firewall rules and even to reboot the entire server to its original state employing a very user-friendly web interface. In addition, you can monitor the used and the available system resources and on the running processes, to have an idea if the eventual growth of your sites will require a package upgrade too. Virtuozzo gives you complete control over your VPS and you will be able to manage everything conveniently, even when you do not have much experience.
