Virtuozzo Containers is software, that is used to generate virtual servers on a physical machine. It allows VPS accounts to be created and controlled independently of each other, so each of them can have its own Operating System as well as a fixed and warranted volume of resources, which include CPU time, disk space, physical memory, et cetera. You'll be able to stop, start or reboot the server, to install different software packages, to perform many different maintenance tasks, to create firewall rules and even to reboot the entire server to its original state by using a very intuitive web interface. You can also monitor the used and the available system resources and on the active processes, to have an idea whether the eventual development of your sites will require a package upgrade too. Virtuozzo provides you with complete control of your VPS and you can manage everything without difficulty, even when you don't have a lot of experience.
