Virtuozzo Containers is software, that's used to make virtual servers on a physical server. It allows VPS accounts to be created and controlled separately of each other, so each one can have its own Operating System plus a fixed and warranted quantity of resources, for example CPU time, disk space, physical memory, et cetera. You can start, stop or reboot the server, to set up many different software packages, to do numerous maintenance tasks, to set up firewall rules and even to reset the entire server to its initial state through a very user-friendly web interface. You may also keep close track of the used and the available resources and on the active processes, so as to have an idea when the eventual development of your websites will require a plan upgrade too. Virtuozzo will give you complete control over your VPS and you're able to manage everything without any difficulty, even when you don't have much experience.
