Virtuozzo Containers is an excellent virtualization solution, that is used to set up virtual machines working independently of one another on a physical server. Every single VPS has an Operating System of its own and can be controlled from the Virtuozzo Control Panel where you will find quite a lot of options that will give you complete control of the entire machine. Using an intuitive, point & click graphical interface, you will be able to start, stop or restart your server whenever you need, to do various maintenance tasks, to recover a file backup, to set up many different server-side software modules, as well as a lot more. The system resource monitoring software tool will give you in-depth info with regard to the performance of your VPS, and if you expand your sites, you can easily see whether your current configuration can handle the extra load, or if you will require some upgrade. When necessary, you will also have the option to re-install the whole VPS container to its original state, resetting any changes you've made.
