Virtuozzo Containers is software, which 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 can have its unique OS in addition to a fixed and warranted volume of resources, including CPU time, disk space, physical memory, and so on. You're able to start, stop or restart the server, to set up different software packages, to perform a variety of maintenance tasks, to create firewall rules and even to reset the entire server to its original state by using a very intuitive online interface. You may also keep close track of the used and the available system resources and on the active processes, so as to have an idea whether the eventual development of your web sites will require a package upgrade as well. Virtuozzo provides you with full control over your VPS and you will be able to control everything conveniently, even if you don't have much experience.
