Virtuozzo Containers is software, that's used to generate virtual servers on a physical server. It allows VPS accounts to be generated and controlled separately of each other, so each one can have its unique OS and a fixed and warranted quantity of system resources, which include CPU time, disk space, physical memory, et cetera. You're able to start, stop or reboot the server, to set up various software packages, to do a variety of maintenance tasks, to set up firewall rules and even to reboot the entire server to its original state by using a very intuitive web interface. You may also keep an eye on the used and the available system resources and on the running processes, to have an idea whether the eventual development of your websites will require a package upgrade too. Virtuozzo will provide you with complete control of your VPS and you are able to control everything easily, even when you do not have a lot of experience.
