Virtuozzo Containers is software, which is used to make virtual servers on a physical hosting server. It allows VPS accounts to be created and handled independently of one another, so each can have its own Operating System plus a fixed and ensured amount of system resources, for instance CPU time, disk space, physical memory, etc. You will be able to start, stop or reboot the server, to install different software packages, to perform many different maintenance tasks, to create firewall rules and even to reset the entire server to its original state by using a very intuitive world-wide web interface. You may also keep track of the used and the available system resources and on the active processes, to have an idea whether the eventual development of your sites will require a package upgrade too. Virtuozzo offers you complete control of your VPS and you are able to manage everything conveniently, even when you don't have much experience.
