Microsoft's Resurgence Under Satya Nadella

Mr. Nadella--Microsoft's third CEO after Bill Gates and Steve Ballmer--soon dismantled the company's mobile-phone operations and began making cloud computing the heart of Microsoft's business. On his watch, revenues from its Azure cloud-computing business have surged and the company's share price has nearly tripled, allowing Microsoft to reclaim the title of the world's most valuable company late last year for the first time since 2003. The company said this week that Azure grew 76% in the just-ended quarter, though a chip-shortage curbed Microsoft's overall sales growth. Mr. Nadella has also made moves to change Microsoft's culture and make it a more vocal corporate citizen, especially as the tech industry faces greater government and public scrutiny. He and other Microsoft executives have been outspoken in their calls for the responsible use of artificial intelligence.
