Virtuozzo Containers is a software solution, that is used to make virtual servers on a physical machine. It allows VPS accounts to be set up and handled separately of one another, so each of them can have its unique Operating System as well as a fixed and guaranteed amount of system resources, for example CPU time, disk space, physical memory, etc. You're able to start, stop or reboot the server, to set up many different software packages, to perform many different maintenance tasks, to create 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 an eye on the used and the available resources and on the running processes, so as to have an idea if the eventual development of your web sites will require a plan upgrade as well. Virtuozzo will give you full control of your VPS and you are able to control everything without any difficulty, even when you don't have much experience.
