Virtuozzo Containers is software, that's used to create virtual servers on a physical server. It allows VPS accounts to be created and controlled independently of each other, so each of them can have its own Operating System plus a fixed and ensured quantity of resources, including CPU time, disk space, physical memory, et cetera. You'll be able to start, stop or reboot the server, to install many different software packages, to perform numerous maintenance tasks, to create firewall rules and even to reset the entire server to its original state by using a very user-friendly web interface. In addition, you can keep an eye on the used and the available system resources and on the running processes, so as to have an idea whether the eventual development of your websites will require a package upgrade too. Virtuozzo offers you complete control of your VPS and you're able to manage everything easily, even if you do not have a lot of experience.
