Virtuozzo Containers is an excellent virtualization solution, that's used to create virtual machines functioning separately of each other on a physical server. Each and every VPS has an OS of its own and it can be managed from the Virtuozzo Control Panel where you can find quite a few options that will provide you with complete control of the whole machine. Using an intuitive, point-and-click graphical interface, you can start, stop or restart your machine whenever you want, to perform different maintenance tasks, to restore a back up copy, to install a number of server-side software modules, as well as many more. The resource monitoring software instrument will give you in-depth information about the overall performance of your VPS, which means that if you expand your sites, you can easily view whether the current configuration can handle the further load, or whether you will require an upgrade. When necessary, you can re-install the VPS container to its initial state, resetting any changes you've made.
