Virtuozzo Containers is software, which is used to generate virtual servers on a physical server. It allows VPS accounts to be set up and controlled independently of one another, so each can have its own OS and a fixed and guaranteed amount of resources, such as CPU time, disk space, physical memory, and so on. You'll be able to start, stop or restart the server, to set up various software packages, to do many different maintenance tasks, to set up firewall rules and even to reboot the entire server to its original state using a very intuitive web interface. In addition, you can keep track of the used and the available system resources and on the running processes, to have an idea if the eventual development of your web sites will require a package upgrade too. Virtuozzo gives you complete control over your VPS and you will be able to control everything easily, even when you do not have a lot of experience.
