Virtuozzo Containers is software, that's used to generate virtual servers on a physical machine. It allows VPS accounts to be set up and handled separately of each other, so each one can have its own OS in addition to a fixed and ensured amount of system resources, such as CPU time, disk space, physical memory, etc. You will be able to start, stop or reboot the server, to set up a variety of software packages, to perform a variety of maintenance tasks, to create firewall rules and even to reboot the entire hosting 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, in order to have an idea when the eventual growth of your sites will require a package upgrade too. Virtuozzo will provide you with full control over your VPS and you are able to control everything without difficulty, even if you don't have much experience.
