Virtuozzo Containers is a software solution, which is used to make virtual servers on a physical hosting server. It allows VPS accounts to be generated and controlled independently of one another, so each can have its own OS as well as a fixed and warranted amount of system resources, for example CPU time, disk space, physical memory, and so on. You'll be able to stop, start or reboot the server, to install different software packages, to perform a variety of maintenance tasks, to create firewall rules and even to reset the entire server to its initial state through a very user-friendly web interface. In addition, you can monitor the used and the available resources and on the active processes, so as to have an idea when the eventual development of your sites will require a package upgrade too. Virtuozzo will give you complete control over your VPS and you can manage everything conveniently, even if you don't have a lot of experience.
