Virtuozzo Containers is a well-liked virtualization platform, that's used to set up virtual servers on physical machines. Every VPS made with it is a separate software emulation of a hosting server, so it has its own OS. The resources are also fixed, so when you buy a VPS plan with certain disk space, CPU and RAM quotas, they'll always be at your disposal and won't be shared with some other customer on the server. The Virtuozzo Containers software is particularly 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 few clicks, you can start/stop/reboot your virtual machine, set firewall rules, set up server-side software packages and do various maintenance tasks. You can also track what amount of resources your web sites use in real time and this data will show you whether you'll need an upgrade while you expand your world-wide web presence. When needed, you can even reset the whole VPS to its original software configuration.
