Virtuozzo Containers is software, that is used to create virtual servers on a physical hosting server. It allows VPS accounts to be created and managed independently of each other, so each can have its very own Operating System as well as a fixed and guaranteed amount of resources, including CPU time, disk space, physical memory, and the like. You are able to start, stop or restart the server, to install various software packages, to do a variety of maintenance tasks, to create firewall rules and even to reset the entire server to its original state using a very intuitive web interface. You can also keep an eye on the used and the available resources and on the active processes, in order to have an idea when the eventual growth of your websites will require a plan upgrade as well. Virtuozzo will provide you with complete control of your VPS and you're able to control everything without difficulty, even if you don't have much experience.
