Virtuozzo Containers is a widely used virtualization platform, that's used to make virtual servers on physical machines. Every VPS made with it is a separate software emulation of a server, therefore it has its own OS. The resources are also fixed, so when you order a VPS package with certain CPU, RAM and disk space quotas, they'll always be at your disposal and won't be shared with some other user on the server. The Virtuozzo Containers software is truly intuitive and user-friendly, so even if you don't have a lot of experience, you'll be able to manage your entire server using a web-based graphical interface. With just a couple of clicks, you will be able to start/stop/reboot the virtual machine, set firewall rules, set up server-side software packages and do various maintenance tasks. You can also keep track of the amount of resources your websites are using live and all this data will show you whether you should have upgrading when you expand your world-wide web presence. If needed, you are able to even reset the entire VPS to its original software setup.
