Scott Guthrie, the leader of Microsoft's Azure cloud business, informed employees that management of the Azure cloud business would undergo modifications. This would involve integrating internal departments and implementing a new framework centered on artificial intelligence. Arun Ulag, previously in charge of Azure database products, will assume leadership of the executive team overseeing Azure's core business and engineering departments. Several pertinent executives, along with Charlie Bell—formerly the head of Microsoft's security business who has since shifted to an advisory position—will report to him. This staff reshuffle is part of a broader series of executive transitions at Microsoft this year, as CEO Satya Nadella is appointing a new cadre of leaders throughout the company and entrusting them with increased business oversight. Internally, Arun Ulag is recognized as one of Nadella's prime candidates for succession.
