Virtuozzo Containers is software, which is used to make 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 OS plus a fixed and guaranteed volume of resources, including CPU time, disk space, physical memory, and so on. You are able to start, stop or restart the server, to set up various software packages, to do a variety of maintenance tasks, to create firewall rules and even to reboot the entire server to its initial state by using a very user-friendly online interface. You can also keep an eye on the used and the available system resources and on the running processes, to have an idea if the eventual growth of your Internet sites will require a plan upgrade too. Virtuozzo will give you complete control of your VPS and you'll be able to manage everything conveniently, even if you don't have much experience.
