Canonical, the commercial presence behind the Ubuntu Linux distribution for servers and desktops, is in business to make money as well as to put out the best free operating system it can. Some businesses won't pay for support, some want basic support, and others (particularly companies making big investments in Linux for the first time) want all the hand-holding they can get. To better address the needs of different sets of customers, Canonical is packaging up its support services in a new way, which it calls Ubuntu Advantage.
