Virtuozzo Containers is software, that's used to create virtual servers on a physical machine. It allows VPS accounts to be set up and managed independently of one another, so each one can have its very own OS as well as a fixed and ensured amount of resources, which include CPU time, disk space, physical memory, and so on. You are able to start, stop or reboot the server, to set up different software packages, to do many different maintenance tasks, to create firewall rules and even to reset the entire server to its original state using a very user-friendly world-wide web interface. In addition, you can keep track of the used and the available resources and on the active processes, in order to have an idea when the eventual development of your websites will require a package upgrade as well. Virtuozzo gives you full control over your VPS and you can manage everything with ease, even if you don't have much experience.
