Virtuozzo Containers is a software solution, that's used to create virtual servers on a physical hosting server. It allows VPS accounts to be set up and controlled independently of each other, so each of them can have its unique OS and a fixed and guaranteed quantity of resources, for instance CPU time, disk space, physical memory, and the like. You're able to start, stop or restart the server, to install a variety of software packages, to perform many different maintenance tasks, to create firewall rules and even to reboot the entire server to its initial state by using a very user-friendly web interface. You can also keep close track of the used and the available system resources and on the running processes, so as to have an idea if the eventual growth of your web sites will require a package upgrade too. Virtuozzo gives you full control of your VPS and you are able to manage everything without difficulty, even when you do not have much experience.
