Virtuozzo Containers is a great virtualization solution, which is used to set up virtual machines working separately of one another on a physical server. Every single VPS has an Operating System of its own and can be managed through the Virtuozzo Control Panel where you'll find lots of options which will give you complete control over the whole machine. Using an intuitive, point and click graphical interface, you can start, stop or reboot your hosting server whenever you need, to perform various maintenance tasks, to restore a data backup, to set up a variety of server-side software modules, as well as many more. The system resource monitoring software tool will give you comprehensive info with regard to the overall performance of your VPS, and if you expand your websites, you can easily view if the current configuration can handle the additional load, or whether you will require some upgrade. When required, you will also have the option to re-install the whole VPS container to its original state, resetting any changes you've made.
