Virtuozzo Containers is software, which is used to create virtual servers on a physical server. It allows VPS accounts to be generated and controlled separately of one another, so each of them can have its unique Operating System plus a fixed and ensured volume of resources, such as CPU time, disk space, physical memory, etc. You will be able to start, stop or reboot the server, to install different software packages, to do a variety of maintenance tasks, to set up firewall rules and even to reboot the entire hosting server to its original state by using a very intuitive web interface. You may also keep an eye on the used and the available system resources and on the active processes, so as to have an idea when the eventual growth of your web sites will require a plan upgrade as well. Virtuozzo will give you complete control of your VPS and you will be able to manage everything with ease, even when you don't have much experience.
