ISVs can use the appliance model to gain significant competitive advantages and operational efficiencies. But to truly gain those benefits, ISVs have to take the right approach with their appliance strategy. ISVs should choose an appliance partner that offers all the elements required for success under the appliance delivery model: hardware engineering and manufacturing, enterprise-grade software for managing appliances over their lifetimes, and the logistics and support services needed to keep an ISV's global customer base up, running and happy. With the right appliance partner, the ISV need not worry about those things, and instead focus their efforts and resources more completely on where they add value and differentiate themselves from their competitors - in application development.
