Virtuozzo Containers is a software solution, that's used to generate virtual servers on a physical server. It allows VPS accounts to be set up and managed separately of each other, so each of them can have its unique Operating System and a fixed and guaranteed amount of resources, including CPU time, disk space, physical memory, and the like. You can start, stop or restart the server, to set up various software packages, to do various maintenance tasks, to create firewall rules and even to reboot the entire server to its original state using a very intuitive online interface. In addition, you can keep an eye on the used and the available resources and on the running processes, so as to have an idea if the eventual growth of your sites will require a package upgrade as well. Virtuozzo will give you complete control of your VPS and you're able to control everything easily, even if you do not have a lot of experience.
