Google's cloud computing chief Diane Greene is leaving the company amid growing tensions with other senior Google executives and after the company failed to make meaningful progress in one of its most important new businesses.
Although Google has struggled to gain market share from Amazon in the cloud business, Ms. Greene’s departure was still abrupt and somewhat surprising. Since 2012, she has been a board member at Google (and later at Alphabet, after the new parent company was formed). She long enjoyed the support of CEO Sundar Pichai, who had backed her efforts to win more cloud business. She will be replaced by Thomas Kurian, a former senior Oracle executive, who will join Google Nov. 26 and assume leadership of its cloud unit in early 2019, Ms. Greene said in a blog post.
