Virtuozzo Containers is a software solution, which is used to make virtual servers on a physical machine. It allows VPS accounts to be generated and controlled independently of one another, so each can have its unique OS as well as a fixed and ensured amount of resources, which include CPU time, disk space, physical memory, et cetera. You're able to start, stop or reboot the server, to install various software packages, to do various maintenance tasks, to create firewall rules and even to reboot the entire server to its original state through a very intuitive web interface. In addition, you can monitor the used and the available resources and on the active processes, so as to have an idea when the eventual development of your sites will require a plan upgrade as well. Virtuozzo will give you full control of your VPS and you'll be able to manage everything with ease, even if you don't have much experience.
