Virtuozzo Containers is a software solution, which is used to create virtual servers on a physical server. It allows VPS accounts to be set up and handled separately of each other, so each of them can have its unique Operating System in addition to a fixed and ensured amount of system resources, for instance CPU time, disk space, physical memory, and so on. You will be able to start, stop or restart the server, to install a variety of software packages, to do numerous maintenance tasks, to set up firewall rules and even to reboot the entire server to its original state through a very user-friendly world-wide web interface. You may also keep an eye on the used and the available resources and on the running processes, so as to have an idea whether the eventual development of your websites will require a package upgrade too. Virtuozzo will give you complete control over your VPS and you'll be able to control everything easily, even when you don't have much experience.
