Nadella most recently served as executive vice president of Microsoft's Cloud and Enterprise group. During his career, he was also president of Microsoft's Server and Tools division, where he was credited with bringing enterprise products to the cloud, as well as senior vice president of research and development for the company's Online Services division.
