Virtuozzo Containers is software, that is used to make virtual servers on a physical hosting server. It allows VPS accounts to be created and controlled independently of each other, so each can have its own OS as well as a fixed and ensured quantity of system resources, for instance CPU time, disk space, physical memory, et cetera. You are able to start, stop or reboot the server, to install various software packages, to perform many different maintenance tasks, to set up firewall rules and even to reset the entire hosting server to its initial state by using a very user-friendly world-wide web interface. You may also keep track of the used and the available resources and on the active processes, so as to have an idea when the eventual growth of your sites will require a package upgrade too. Virtuozzo will give you complete control of your VPS and you're able to manage everything with ease, even if you don't have a lot of experience.
