Virtuozzo Containers is a widespread virtualization platform, that is used to generate virtual servers on physical machines. Each VPS made with it is a separate software emulation of a website hosting server, so it has its own OS. The system resources are also fixed, therefore if you purchase a VPS package with certain disk space, RAM and CPU quotas, they will always be at your disposal and will not be shared with some other user on the physical server. The Virtuozzo Containers software is particularly intuitive and user-friendly, so even if you don't have a lot of experience, you can control the whole server with a web-based graphical interface. With a couple of clicks, you can easily start/stop/reboot your virtual machine, set firewall rules, set up server-side software applications and perform various maintenance tasks. You can also keep track of how much system resources your Internet sites use live and all of this information will tell you whether you will need upgrading as you expand your web presence. If needed, you are able to even reset the entire VPS to its original software setup.
