Virtuozzo Containers is a software solution, which is used to make virtual servers on a physical server. It allows VPS accounts to be set up and managed independently of each other, so each one can have its very own OS as well as a fixed and guaranteed volume of resources, for example CPU time, disk space, physical memory, and the like. You're able to stop, start or reboot the server, to install different software packages, to do numerous maintenance tasks, to create firewall rules and even to reboot the entire server to its initial state through a very user-friendly web interface. You may also keep close track of 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 full control of your VPS and you're able to manage everything effortlessly, even if you don't have much experience.
