Virtuozzo Containers is a great virtualization solution, that is used to install virtual machines operating independently of each other on a physical server. Every single VPS has an Operating System of its own and can be controlled through the Virtuozzo Control Panel where you'll be able to find lots of options that will provide you with complete control over the entire machine. Using a user-friendly, point & click graphical interface, you can start, stop or reboot your machine at any time, to perform different maintenance tasks, to restore a backup, to install various server-side software modules, plus many more. The system resource monitoring instrument will give you detailed info for the performance of your VPS, and if you expand your web sites, you can easily view if your current configuration can handle the further load, or if you will need an upgrade. If required, you will also have the option to reinstall the VPS container to its default state, resetting any changes you've made.
