Virtuozzo Containers is software, which is used to generate virtual servers on a physical machine. It allows VPS accounts to be set up and handled independently of each other, so each of them can have its unique Operating System plus a fixed and warranted quantity of resources, which include CPU time, disk space, physical memory, etc. You can stop, start or reboot the server, to install various software packages, to perform a variety of maintenance tasks, to create firewall rules and even to reboot the entire server to its initial state through a very user-friendly world-wide web interface. You can also keep an eye on the used and the available resources and on the active processes, so as to have an idea when the eventual growth of your sites will require a plan upgrade as well. Virtuozzo gives you full control over your VPS and you're able to manage everything without any difficulty, even when you do not have a lot of experience.
