Virtuozzo Containers is a software solution, that is used to generate virtual servers on a physical server. It allows VPS accounts to be set up and controlled separately of each other, so each one can have its very own OS as well as a fixed and guaranteed amount of resources, for instance CPU time, disk space, physical memory, etc. You're able to start, stop or restart the server, to set up a variety of software packages, to perform various maintenance tasks, to create firewall rules and even to reset the entire hosting server to its initial state employing a very intuitive web interface. You may also keep track of the used and the available resources and on the active processes, to have an idea when the eventual development of your web sites will require a package upgrade as well. Virtuozzo will provide you with full control over your VPS and you are able to control everything without difficulty, even if you don't have a lot of experience.
