Virtuozzo Containers is software, that is used to make virtual servers on a physical server. It allows VPS accounts to be generated and handled separately of one another, so each one can have its unique OS as well as a fixed and guaranteed amount of resources, such as CPU time, disk space, physical memory, and so on. You are able to start, stop or reboot the server, to install different software packages, to do many different maintenance tasks, to set up firewall rules and even to reboot the entire server to its initial state by using a very user-friendly web interface. You may also keep close track of the used and the available system resources and on the active processes, in order to have an idea if the eventual growth of your web sites will require a plan upgrade too. Virtuozzo will provide you with full control of your VPS and you can manage everything effortlessly, even when you don't have a lot of experience.
