Virtuozzo Containers is software, that is used to make virtual servers on a physical machine. It allows VPS accounts to be generated and controlled independently of each other, so each can have its unique OS and a fixed and ensured quantity of resources, including CPU time, disk space, physical memory, and the like. You are able to start, stop or reboot the server, to install various software packages, to do a variety of maintenance tasks, to set up firewall rules and even to reset the entire hosting server to its initial state using a very user-friendly web interface. You may also monitor the used and the available resources and on the active processes, to have an idea whether the eventual growth of your Internet sites will require a package upgrade as well. Virtuozzo offers you full control over your VPS and you can control everything without any difficulty, even if you don't have a lot of experience.
