Virtuozzo Containers is a widespread virtualization platform, that is used to make virtual servers on physical machines. Each VPS made with it is a separate software emulation of a server, which means that it has its own OS. The system resources are also fixed, therefore if you obtain a VPS plan with certain disk space, RAM and CPU quotas, they will always be available and won't be shared with another customer on the physical server. The Virtuozzo Containers software is exceptionally intuitive and user-friendly, so even if you do not have a lot of experience, you'll be able to manage the whole server with a web-based graphical interface. With a few clicks, you will be able to start/stop/reboot your virtual machine, manage firewall rules, set up server-side software packages and perform various maintenance tasks. You can also keep track of what amount of system resources your websites are using in real time and all this info will tell you whether you should have upgrading while you expand your online presence. When needed, you are able to even reset the entire VPS to its original software setup.
