Virtuozzo Containers is software, that is used to make virtual servers on a physical machine. It allows VPS accounts to be created and managed separately of each other, so each of them can have its own Operating System plus a fixed and ensured amount of resources, such as CPU time, disk space, physical memory, and the like. You can start, stop or restart the server, to install many different software packages, to do numerous maintenance tasks, to create firewall rules and even to reboot the entire server to its original state employing a very user-friendly web interface. In addition, you can keep track of the used and the available resources and on the active processes, to have an idea whether the eventual development of your sites will require a plan upgrade too. Virtuozzo gives you complete control over your VPS and you will be able to control everything without difficulty, even when you do not have much experience.
