Virtuozzo Containers is software, which is used to make virtual servers on a physical hosting server. It allows VPS accounts to be set up and controlled independently of each other, so each of them can have its own OS as well as a fixed and guaranteed amount of resources, for example CPU time, disk space, physical memory, et cetera. You will be able to start, stop or restart the server, to set up various software packages, to do many different maintenance tasks, to create firewall rules and even to reset the entire server to its initial state by using a very user-friendly world-wide web interface. You can also monitor the used and the available resources and on the active processes, in order to have an idea when the eventual development of your web sites will require a plan upgrade too. Virtuozzo gives you complete control of your VPS and you're able to manage everything without any difficulty, even if you don't have much experience.
