The VPS allows you to install software as needed, but most of them has a control panel such as Plesk, DirectAdmin, cPanel or other products for the management of web sites and all their settings.
These panels appear to be very comfortable because they allow you to manage individual domains in all their aspects: creating new spaces, databases, email accounts, autoresponders, managing spam filters and all that is usually necessary for the administration of the system but they sucks the system resources themselves.
In addition, these panels also allow access to more people with different levels of access and consequent privileges, leaving so that individual web spaces within the VPS can be resold to third party customers, as in the case of webagency that develop web sites for their customers. A VPS, however, has other advantages : Each VPS is assigned one or more dedicated IP, these allow you to install SSL certificates to support e-commerce sites or websites where there is a need to have a secure connection, just because data is stored sensitive.
