Virtuozzo Containers is software, that's used to make virtual servers on a physical server. It allows VPS accounts to be created and controlled independently of one another, so each one can have its own OS in addition to a fixed and guaranteed amount of resources, for instance CPU time, disk space, physical memory, etc. 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 original state employing a very user-friendly world-wide web interface. In addition, you can keep close track of the used and the available system resources and on the running processes, so as to have an idea if the eventual growth of your sites will require a plan upgrade as well. Virtuozzo will provide you with complete control over your VPS and you'll be able to control everything with ease, even if you don't have a lot of experience.
