Cloud services in general have experienced a decade of explosive growth, eliminating barriers  in reaching users and enabling real-time interchanges and intelligence. Cloud services are  increasingly embedded in the day-to-day activities of businesses and consumers. Due to the evolution in cloud business models, new issues are surfacing to challenge practitioners and scholars, and some of them can be adequately  addressed with game theory. In this talk, I attempt to fill this important gap. I use a trending  framework and cover various themes in cloud service pricing, product, and operations. For  each theme, we review past work that has been instrumental in setting the direction of this  line of research and discuss how emerging research opportunities can be addressed. I conclude by describing promising directions on a roadmap for future research and explain  why the use of game theory could build an integrative perspective of cloud service research.
