Virtuozzo Containers is software, that's used to create virtual servers on a physical machine. It allows VPS accounts to be generated and managed separately of each other, so each of them can have its own OS plus a fixed and ensured amount of system resources, such as CPU time, disk space, physical memory, and so on. You'll be able to start, stop or restart the server, to set up a variety of software packages, to do a variety of maintenance tasks, to create firewall rules and even to reset the entire server to its original state using a very intuitive online interface. You may also monitor the used and the available resources and on the active processes, in order to have an idea when the eventual growth of your Internet sites will require a plan upgrade as well. Virtuozzo will give you complete control over your VPS and you are able to manage everything without any difficulty, even if you don't have much experience.
