Virtuozzo Containers is a software solution, that is used to make virtual servers on a physical server. It allows VPS accounts to be created and controlled separately of one another, so each of them can have its unique OS in addition to a fixed and guaranteed volume of resources, which include CPU time, disk space, physical memory, etc. You will be able to start, stop or reboot the server, to install many different software packages, to perform various maintenance tasks, to create firewall rules and even to reboot the entire server to its initial state through a very user-friendly world-wide web interface. You can also keep close track of the used and the available resources and on the active processes, so as to have an idea if the eventual development of your sites will require a package upgrade too. Virtuozzo will give you full control over your VPS and you will be able to manage everything easily, even when you do not have a lot of experience.
