Virtuozzo Containers is a software solution, that's used to generate virtual servers on a physical server. It allows VPS accounts to be created and controlled independently of one another, so each of them can have its own OS in addition to a fixed and guaranteed volume of system resources, including CPU time, disk space, physical memory, and the like. You will be able to start, stop or restart the server, to install a variety of software packages, to do various maintenance tasks, to create firewall rules and even to reset the entire server to its original state using a very user-friendly web interface. You may also keep close track of the used and the available resources and on the running processes, so as to have an idea whether the eventual development of your sites will require a package upgrade too. Virtuozzo offers you full control over your VPS and you are able to control everything effortlessly, even if you don't have a lot of experience.
