Virtuozzo Containers is software, that is used to make virtual servers on a physical server. It allows VPS accounts to be set up and controlled independently of each other, so each can have its unique OS and a fixed and guaranteed volume of system resources, including CPU time, disk space, physical memory, et cetera. You are able to start, stop or reboot the server, to install many different software packages, to perform various maintenance tasks, to create firewall rules and even to reset the entire hosting server to its original state employing a very intuitive world-wide web interface. You may also monitor the used and the available resources and on the running processes, in order to have an idea when the eventual development of your Internet sites will require a package upgrade too. Virtuozzo will give you complete control over your VPS and you can manage everything effortlessly, even when you don't have much experience.
