Virtuozzo Containers is a widespread virtualization platform, that is used to set up virtual servers on physical machines. Each VPS created with it is a separate software emulation of a server, so it has its own OS. The resources are also predefined, which means that when you obtain a VPS plan with certain disk space, RAM and CPU allocations, they'll always be at your disposal and will not be shared with some other user on the server. The Virtuozzo Containers software is very intuitive and user-friendly, so even if you don't have much experience, you can manage your entire server with a web-based graphical interface. With only a couple of clicks, you can start/stop/reboot the virtual machine, set firewall rules, set up server-side software and do numerous maintenance tasks. You can also keep track of the amount of resources your Internet sites use in real time and all this data will inform you whether you should have an upgrade while you expand your web presence. When needed, you can even reset the whole VPS to its original software configuration.
