Virtuozzo Containers is a software solution, which is used to make virtual servers on a physical machine. It allows VPS accounts to be generated and controlled separately of each other, so each can have its very own OS in addition to a fixed and guaranteed amount of resources, which include CPU time, disk space, physical memory, and so on. You are able to start, stop or reboot the server, to set up various software packages, to perform various maintenance tasks, to set up firewall rules and even to reboot the entire server to its original state through a very user-friendly online interface. You can also monitor the used and the available system resources and on the running processes, in order to have an idea when the eventual development of your sites will require a package upgrade as well. Virtuozzo gives you full control of your VPS and you're able to control everything without any difficulty, even when you don't have a lot of experience.
