Virtuozzo Containers is a software solution, that's used to create virtual servers on a physical machine. It allows VPS accounts to be generated and controlled independently of one another, so each of them can have its own Operating System in addition to a fixed and warranted quantity of resources, for instance CPU time, disk space, physical memory, et cetera. You're able to start, stop or reboot the server, to set up many different software packages, to do many different maintenance tasks, to set up 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 active processes, to have an idea whether the eventual development of your websites will require a package upgrade too. Virtuozzo will give you complete control over your VPS and you are able to manage everything easily, even if you don't have much experience.
