Virtuozzo Containers is a software solution, which is used to make virtual servers on a physical machine. It allows VPS accounts to be created and managed independently of each other, so each of them can have its own OS and a fixed and warranted volume of resources, for instance CPU time, disk space, physical memory, and the like. You are able to stop, start or reboot the server, to set up different software packages, to perform many different maintenance tasks, to create firewall rules and even to reboot the entire hosting server to its initial state by using a very intuitive online interface. You can also keep an eye on the used and the available system resources and on the running processes, in order to have an idea if the eventual growth of your web sites will require a package upgrade as well. Virtuozzo gives you full control of your VPS and you are able to manage everything easily, even when you don't have a lot of experience.
