Virtuozzo Containers is software, that is used to make virtual servers on a physical server. It allows VPS accounts to be generated and handled independently of one another, so each one can have its unique Operating System plus a fixed and guaranteed amount of system resources, which include CPU time, disk space, physical memory, et cetera. You will be able to stop, start or reboot the server, to install various software packages, to do various maintenance tasks, to set up firewall rules and even to reboot the entire hosting server to its initial state by using a very user-friendly online interface. You may also monitor the used and the available system resources and on the running processes, so as to have an idea whether the eventual growth of your sites will require a package upgrade too. Virtuozzo will provide you with full control of your VPS and you'll be able to manage everything effortlessly, even if you don't have a lot of experience.
