Virtuozzo Containers is software, that's used to create virtual servers on a physical machine. It allows VPS accounts to be set up and controlled independently of one another, so each of them can have its own OS as well as a fixed and guaranteed volume of system resources, for example CPU time, disk space, physical memory, etc. You can stop, start or reboot the server, to install various software packages, to do various maintenance tasks, to create firewall rules and even to reboot the entire hosting server to its original state by using a very user-friendly world-wide web interface. You can also keep track of the used and the available system resources and on the active processes, in order to have an idea whether the eventual growth of your websites will require a plan upgrade as well. Virtuozzo will provide you with complete control of your VPS and you will be able to manage everything conveniently, even if you do not have much experience.
