Virtuozzo Containers is software, that is used to generate virtual servers on a physical hosting server. It allows VPS accounts to be set up and managed separately of one another, so each one can have its unique Operating System and a fixed and guaranteed amount of resources, for example CPU time, disk space, physical memory, and so on. You're able to stop, start or reboot the server, to install different software packages, to perform numerous maintenance tasks, to create firewall rules and even to reboot the entire server to its initial state by using a very user-friendly world-wide web interface. You can also keep an eye on the used and the available system resources and on the running processes, to have an idea if the eventual growth of your sites will require a package upgrade as well. Virtuozzo will give you full control of your VPS and you will be able to manage everything without difficulty, even if you do not have a lot of experience.
