Virtuozzo Containers is software, which is used to make virtual servers on a physical machine. It allows VPS accounts to be generated and managed independently of one another, so each can have its own OS in addition to a fixed and guaranteed amount of system resources, such as CPU time, disk space, physical memory, et cetera. You're able to start, stop or restart the server, to set up many different software packages, to perform numerous maintenance tasks, to set up firewall rules and even to reboot the entire hosting server to its original state through a very intuitive web interface. You can also keep an eye on the used and the available resources and on the running processes, in order to have an idea if the eventual development of your web sites will require a plan upgrade too. Virtuozzo offers you complete control over your VPS and you'll be able to manage everything easily, even when you don't have much experience.
