Virtuozzo Containers is software, that is used to generate virtual servers on a physical server. It allows VPS accounts to be set up and controlled separately of each other, so each of them can have its very own Operating System and a fixed and warranted amount of system resources, such as CPU time, disk space, physical memory, and the like. You're able to start, stop or restart the server, to set up different software packages, to perform various maintenance tasks, to create firewall rules and even to reset the entire server to its original state through a very intuitive 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 growth of your Internet sites will require a package upgrade too. Virtuozzo gives you complete control of your VPS and you will be able to control everything easily, even if you do not have a lot of experience.
