Virtuozzo Containers is software, that is used to generate virtual servers on a physical machine. It allows VPS accounts to be set up and controlled separately of each other, so each one can have its very own OS as well as a fixed and ensured amount of system resources, including CPU time, disk space, physical memory, etc. You can start, stop or reboot the server, to set up different software packages, to do various maintenance tasks, to set up firewall rules and even to reboot the entire server to its original state using a very intuitive web interface. You can also keep track of the used and the available resources and on the running processes, in order to have an idea if the eventual development of your Internet sites will require a package upgrade as well. Virtuozzo will provide you with full control over your VPS and you are able to manage everything with ease, even if you do not have a lot of experience.
