Virtuozzo Containers is software, that is used to make virtual servers on a physical server. It allows VPS accounts to be created and managed separately of each other, so each one can have its very own Operating System plus a fixed and guaranteed volume of resources, which include CPU time, disk space, physical memory, and so on. You will be able to start, stop or restart the server, to install many different software packages, to perform many different maintenance tasks, to set up firewall rules and even to reset the entire hosting server to its initial state using a very user-friendly world-wide web interface. You can also monitor the used and the available system resources and on the running processes, so as to have an idea when the eventual development of your web sites will require a package upgrade too. Virtuozzo provides you with complete control of your VPS and you'll be able to control everything easily, even if you don't have a lot of experience.
