Virtuozzo Containers is software, that is used to generate virtual servers on a physical server. It allows VPS accounts to be generated and controlled separately of each other, so each can have its own OS as well as a fixed and ensured volume of resources, which include CPU time, disk space, physical memory, etc. You're able to start, stop or restart the server, to install various software packages, to do numerous maintenance tasks, to set up firewall rules and even to reset the entire hosting server to its initial state using a very user-friendly online interface. You may also keep close track of the used and the available resources and on the active processes, to have an idea if 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'll be able to control everything effortlessly, even when you don't have much experience.
