Virtuozzo Containers is a popular virtualization platform, that's used to set up virtual servers on physical machines. Each VPS made with it is a standalone software emulation of a website hosting server, therefore it has its own Operating System. The resources are also predefined, which means that if you obtain a VPS plan with certain disk space, CPU and RAM allocations, they'll always be at your disposal and will not be shared with another client on the physical server. The Virtuozzo Containers software is really intuitive and easy to use, so even if you don't have a lot of experience, you can manage the entire server with a web-based graphical interface. With only a couple of clicks, you can easily start/stop/reboot the virtual machine, manage firewall rules, set up server-side software and do a number of maintenance tasks. You may also monitor what amount of system resources your Internet sites use live and this data can show you whether you will need an upgrade while you expand your world-wide web presence. If needed, you can even reset the entire VPS to its original software configuration.
