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 handled independently of each other, so each can have its very own OS as well as a fixed and guaranteed volume of resources, such as CPU time, disk space, physical memory, etc. You can stop, start or reboot the server, to set up various software packages, to do many different maintenance tasks, to set up firewall rules and even to reset the entire hosting server to its initial state through a very intuitive online interface. In addition, you can keep an eye on the used and the available resources and on the active processes, to have an idea whether the eventual development of your web sites will require a package upgrade as well. Virtuozzo will provide you with complete control over your VPS and you are able to control everything effortlessly, even if you don't have a lot of experience.
