Virtuozzo Containers is a software solution, that is used to make virtual servers on a physical machine. It allows VPS accounts to be generated and controlled separately of one another, so each can have its very own OS as well as a fixed and guaranteed amount of system resources, for instance CPU time, disk space, physical memory, and the like. You'll be able to stop, start or reboot the server, to set up many different software packages, to perform various maintenance tasks, to create firewall rules and even to reboot the entire hosting server to its original state through a very intuitive world-wide web interface. You can also monitor the used and the available system resources and on the running processes, so as to have an idea when the eventual development of your web sites will require a package upgrade too. Virtuozzo will give you complete control over your VPS and you'll be able to control everything without difficulty, even if you don't have much experience.
