Virtuozzo Containers is software, which is used to create virtual servers on a physical machine. It allows VPS accounts to be generated and controlled independently of one another, so each of them can have its unique Operating System plus a fixed and guaranteed quantity of resources, including CPU time, disk space, physical memory, et cetera. You'll be able to start, stop or restart 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 through a very user-friendly web interface. You may also monitor the used and the available resources and on the running processes, in order to have an idea if the eventual development of your web sites will require a plan upgrade too. Virtuozzo will give you complete control of your VPS and you can control everything without any difficulty, even when you do not have a lot of experience.
