Virtuozzo Containers is software, which is used to create virtual servers on a physical server. It allows VPS accounts to be created and controlled separately of each other, so each of them can have its own Operating System in addition to a fixed and ensured volume of resources, including CPU time, disk space, physical memory, et cetera. You will be able to stop, start or reboot the server, to install different software packages, to do various maintenance tasks, to set up firewall rules and even to reboot the entire server to its initial state using a very intuitive online interface. In addition, you can keep close track of the used and the available system resources and on the running processes, to have an idea if the eventual development of your sites will require a package upgrade as well. Virtuozzo will give you complete control over your VPS and you are able to manage everything without difficulty, even if you don't have much experience.
