The whole "Thinking of" series focusing on the Smart Questions is a brilliant concept. These books encourage an informed debate rather than prescribing a specific path which may not be the right one for your business. This book is an invaluable resource for ISVs. The authors have done a great job in articulating the opportunities and the challenges ISVs face in this transition to a Software plus Services world. Although targeted at ISVs, in my view, it is equally valuable for customers so they can assess the capability of their software suppliers in providing resilient and capable Cloud services.
