Virtuozzo Containers is software, that's used to make virtual servers on a physical hosting server. It allows VPS accounts to be generated and managed independently of each other, so each of them can have its unique Operating System and a fixed and ensured amount of resources, for example CPU time, disk space, physical memory, and so on. You are able to start, stop or reboot the server, to set up a variety of software packages, to do many different maintenance tasks, to set up firewall rules and even to reboot the entire hosting server to its original state through a very user-friendly web interface. You can also keep track of the used and the available system resources and on the active processes, so as to have an idea whether the eventual development of your web sites will require a package upgrade as well. Virtuozzo will give you full control over your VPS and you can control everything without any difficulty, even when you don't have a lot of experience.
