Virtuozzo Containers is software, that's used to make virtual servers on a physical server. It allows VPS accounts to be generated and handled independently of each other, so each of them can have its very own Operating System in addition to a fixed and guaranteed volume of system resources, which include CPU time, disk space, physical memory, etc. You are able to start, stop or restart the server, to set up a variety of software packages, to perform a variety of maintenance tasks, to create firewall rules and even to reset the entire server to its initial state through a very user-friendly web interface. You can also keep track of the used and the available system resources and on the active processes, so as to have an idea when the eventual development of your sites will require a package upgrade as well. Virtuozzo offers you complete control over your VPS and you're able to control everything without any difficulty, even if you do not have a lot of experience.
