Virtuozzo Containers is software, that is used to generate virtual servers on a physical machine. It allows VPS accounts to be generated and managed independently of each other, so each can have its very own Operating System plus a fixed and ensured volume of system resources, which include CPU time, disk space, physical memory, etc. You're able to stop, start or reboot the server, to install a variety of software packages, to perform numerous maintenance tasks, to set up firewall rules and even to reset the entire server to its original state employing a very intuitive world-wide web interface. You can also keep close track of the used and the available resources and on the active processes, to have an idea whether the eventual development of your web sites will require a package upgrade as well. Virtuozzo gives you full control over your VPS and you're able to control everything easily, even if you don't have a lot of experience.
