Virtuozzo Containers is software, which is used to create virtual servers on a physical machine. It allows VPS accounts to be set up and controlled independently of each other, so each can have its unique OS in addition to a fixed and warranted volume of system resources, such as CPU time, disk space, physical memory, etc. You can start, stop or reboot the server, to set up different software packages, to do numerous maintenance tasks, to set up firewall rules and even to reboot the entire server to its original state using a very intuitive online interface. You may also keep close track of the used and the available system resources and on the running processes, to have an idea when the eventual development of your sites will require a plan upgrade as well. Virtuozzo will give you full control of your VPS and you can control everything without any difficulty, even when you do not have a lot of experience.
