Virtuozzo Containers is software, which is used to create virtual servers on a physical machine. It allows VPS accounts to be generated and handled separately of one another, so each one can have its unique OS plus a fixed and ensured quantity of system resources, such as CPU time, disk space, physical memory, and so on. You can start, stop or reboot the server, to set up a variety of software packages, to perform numerous maintenance tasks, to create firewall rules and even to reboot the entire hosting server to its initial state through a very intuitive world-wide web interface. You can also keep track of the used and the available system resources and on the running processes, to have an idea when the eventual development of your web sites will require a package upgrade as well. Virtuozzo gives you full control over your VPS and you'll be able to control everything easily, even when you don't have a lot of experience.
