Virtuozzo Containers is an excellent virtualization solution, that is used to set up virtual machines operating independently of each other on a physical server. Each and every VPS has an OS of its own and can be managed through the Virtuozzo Control Panel where you can find quite a lot of options which will provide you with complete control over the entire machine. Employing a user-friendly, point-and-click graphical interface, you will be able to start, stop or reboot your machine at any moment, to do different maintenance tasks, to recover a backup, to set up a variety of server-side software modules, plus many more. The system resource monitoring tool will give you detailed info with regard to the performance of your VPS, so if you expand your web sites, you can easily find whether the current configuration can handle the additional load, or whether you will need an upgrade. When required, you will also have the option to re-install the whole VPS container to its initial state, resetting any changes you've made.
