Virtuozzo Containers is a software solution, that is used to create virtual servers on a physical machine. It allows VPS accounts to be created and controlled independently of each other, so each of them can have its very own OS plus a fixed and ensured amount of resources, for instance CPU time, disk space, physical memory, and so on. You can stop, start or reboot the server, to set up many 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 using a very intuitive web interface. You may also keep close track of the used and the available resources and on the running processes, so as to have an idea if the eventual development of your sites will require a package upgrade as well. Virtuozzo provides you with complete control of your VPS and you will be able to control everything with ease, even if you don't have much experience.
