Virtuozzo Containers is software, that is used to generate virtual servers on a physical machine. It allows VPS accounts to be set up and controlled separately of each other, so each can have its very own Operating System plus a fixed and ensured amount of resources, including CPU time, disk space, physical memory, etc. You'll be able to start, stop or restart the server, to install a variety of software packages, to do numerous maintenance tasks, to set up firewall rules and even to reset the entire server to its original state employing a very user-friendly online interface. You may also keep an eye on the used and the available resources and on the running processes, in order to have an idea whether the eventual development of your websites will require a plan upgrade too. Virtuozzo will give you complete control over your VPS and you're able to manage everything with ease, even when you don't have much experience.
