Virtuozzo Containers is software, that's used to make virtual servers on a physical server. It allows VPS accounts to be created and handled separately of each other, so each can have its very own Operating System and a fixed and guaranteed amount of resources, including CPU time, disk space, physical memory, et cetera. You are able to start, stop or restart the server, to set up various software packages, to do a variety of maintenance tasks, to create firewall rules and even to reboot the entire hosting server to its initial state 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, in order to have an idea if the eventual growth of your sites will require a package upgrade too. Virtuozzo will provide you with complete control over your VPS and you'll be able to manage everything without difficulty, even when you do not have a lot of experience.
