Virtuozzo Containers is software, that is used to make virtual servers on a physical machine. It allows VPS accounts to be created and handled independently of one another, so each of them can have its own Operating System in addition to a fixed and ensured amount of system resources, for instance CPU time, disk space, physical memory, and the like. You will be able to stop, start or reboot the server, to install many different software packages, to do many different maintenance tasks, to create firewall rules and even to reset the entire hosting server to its original state employing a very user-friendly online interface. You can also keep close track of the used and the available resources and on the active processes, so as to have an idea if the eventual growth of your websites will require a plan upgrade as well. Virtuozzo will give you complete control of your VPS and you'll be able to manage everything conveniently, even if you don't have much experience.
