Virtuozzo Containers is software, that's used to generate virtual servers on a physical machine. It allows VPS accounts to be created and handled independently of each other, so each of them can have its unique OS as well as a fixed and warranted volume of resources, which include CPU time, disk space, physical memory, etc. You can stop, start or reboot the server, to set up a variety of software packages, to perform a variety of maintenance tasks, to create firewall rules and even to reboot the entire server to its initial state by using a very user-friendly online interface. You may also keep an eye on the used and the available resources and on the running processes, to have an idea when the eventual development of your sites will require a plan upgrade too. Virtuozzo will provide you with full control of your VPS and you will be able to manage everything easily, even if you do not have much experience.
