Virtuozzo Containers is software, that is used to create virtual servers on a physical machine. It allows VPS accounts to be created and controlled independently of each other, so each can have its own OS as well as a fixed and ensured amount of resources, such as CPU time, disk space, physical memory, et cetera. You can start, stop or reboot the server, to install various 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 keep close track of the used and the available resources and on the running processes, to have an idea whether the eventual development of your Internet sites will require a package upgrade too. Virtuozzo offers you full control of your VPS and you will be able to control everything conveniently, even when you don't have a lot of experience.
