Virtuozzo Containers is a widely used virtualization platform, which is used to generate virtual servers on physical machines. Each VPS made with it is a separate software emulation of a server, therefore it has its own OS. The system resources are also preset, which means that when you order a VPS plan with certain disk space, CPU and RAM quotas, they're always available and won't be shared with some other client on the physical server. The Virtuozzo Containers software is exceptionally intuitive and easy to use, so even if you do not have a lot of experience, you will be able to control the entire server using a web-based graphical interface. With only a couple of clicks, you can start/stop/reboot your virtual machine, manage firewall rules, set up server-side software applications and do various maintenance tasks. You can also watch what amount of system resources your sites use in real time and this data will show you whether you should have upgrading as you expand your web presence. When needed, you'll be able to even reset the whole VPS to its original software configuration.
