Virtuozzo Containers is software, that's used to generate virtual servers on a physical server. It allows VPS accounts to be set up and controlled independently of one another, so each can have its very own OS and a fixed and guaranteed amount of resources, such as CPU time, disk space, physical memory, etc. You will be able to start, stop or reboot the server, to set up 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 through a very user-friendly online interface. In addition, you can monitor the used and the available resources and on the active processes, so as to have an idea when the eventual growth of your websites will require a plan upgrade too. Virtuozzo will provide you with full control over your VPS and you'll be able to control everything effortlessly, even if you do not have much experience.
