Virtuozzo Containers is a software solution, that is used to make virtual servers on a physical hosting server. It allows VPS accounts to be generated and controlled separately of each other, so each can have its own Operating System in addition to a fixed and warranted volume of resources, for instance CPU time, disk space, physical memory, and the like. You can start, stop or restart the server, to install different software packages, to do many different maintenance tasks, to set up firewall rules and even to reboot the entire server to its initial state through a very user-friendly online interface. You can also keep track of the used and the available system resources and on the running processes, in order to have an idea whether the eventual growth of your websites will require a plan upgrade too. Virtuozzo will give you full control over your VPS and you'll be able to control everything without any difficulty, even when you do not have a lot of experience.
