Virtuozzo Containers is software, that is used to generate virtual servers on a physical server. It allows VPS accounts to be created and handled separately of each other, so each one can have its own Operating System as well as a fixed and guaranteed amount of resources, for instance CPU time, disk space, physical memory, et cetera. You will be able to start, stop or reboot the server, to install a variety of software packages, to do various maintenance tasks, to create firewall rules and even to reset the entire server to its initial state using a very intuitive world-wide web interface. You can also keep close track of the used and the available system resources and on the running processes, in order to have an idea whether the eventual development of your web sites will require a plan upgrade as well. Virtuozzo will give you full control of your VPS and you will be able to manage everything with ease, even if you don't have much experience.
