Virtuozzo Containers is an excellent virtualization solution, which is used to create virtual machines functioning separately of one another on a physical server. Each VPS has an Operating System of its own and it can be managed through your Virtuozzo Control Panel where you'll be able to find a wide range of options that will give you complete control over the entire machine. Using an intuitive, point-and-click graphical interface, you'll be able to start, stop or restart your machine at any moment, to perform different maintenance tasks, to restore a backup, to install various server-side software modules, and a lot more. The resource monitoring tool will give you comprehensive info with regard to the overall performance of your VPS, so if you expand your websites, you can easily find if the current configuration can handle the extra load, or whether you will need an upgrade. If needed, you can re-install the whole VPS container to its initial state, resetting any changes you have made.
