Virtuozzo Containers is software, which is used to generate virtual servers on a physical machine. It allows VPS accounts to be generated and handled independently of each other, so each can have its own Operating System in addition to a fixed and ensured quantity of system resources, for example CPU time, disk space, physical memory, etc. You can start, stop or restart the server, to set up different software packages, to do various maintenance tasks, to create firewall rules and even to reset the entire hosting server to its initial state by using a very intuitive web interface. You can also keep close track of the used and the available resources and on the running processes, so as to have an idea when the eventual development of your websites will require a plan upgrade as well. Virtuozzo will give you complete control over your VPS and you're able to manage everything easily, even if you don't have a lot of experience.
