Virtuozzo Containers is software, that's used to create virtual servers on a physical machine. It allows VPS accounts to be created and controlled independently of one another, so each one can have its unique OS in addition to a fixed and ensured amount of resources, including CPU time, disk space, physical memory, etc. You can start, stop or restart the server, to install various software packages, to do numerous maintenance tasks, to set up firewall rules and even to reset the entire server to its original state through a very user-friendly web interface. In addition, you can keep track of the used and the available system resources and on the running processes, to have an idea if the eventual growth of your Internet sites will require a plan upgrade too. Virtuozzo gives you full control of your VPS and you can manage everything with ease, even if you do not have much experience.
