Virtuozzo Containers is software, that's used to create virtual servers on a physical machine. It allows VPS accounts to be set up and handled independently of one another, so each one can have its very own Operating System plus a fixed and warranted amount of resources, for instance CPU time, disk space, physical memory, and the like. You will be able to start, stop or reboot the server, to set up various software packages, to do many different maintenance tasks, to create firewall rules and even to reset the entire server to its initial state employing a very user-friendly web interface. You can also keep track of the used and the available resources and on the active processes, so as to have an idea when the eventual development of your sites will require a package upgrade too. Virtuozzo will provide you with complete control of your VPS and you are able to control everything effortlessly, even when you don't have a lot of experience.
