Virtuozzo Containers is software, which is used to make virtual servers on a physical machine. It allows VPS accounts to be created and handled separately of each other, so each of them can have its very own Operating System in addition to a fixed and ensured amount of system resources, for instance CPU time, disk space, physical memory, and the like. You're able to start, stop or reboot the server, to install various software packages, to do a variety of maintenance tasks, to create firewall rules and even to reset the entire hosting server to its initial state employing a very intuitive world-wide web interface. You can also keep an eye on the used and the available resources and on the running processes, to have an idea if the eventual development of your websites will require a package upgrade as well. Virtuozzo will give you full control over your VPS and you are able to control everything without any difficulty, even when you don't have a lot of experience.
