SAN FRANCISCO — Microsoft plans to shed thousands of jobs at a significant reboot to focus on its fast-growing business that is cloud-computing.

“Microsoft is implementing modifications to better serve our clients and partners,” Microsoft said in a statement to USA TODAY.   “Today, we’re taking steps to notify some employees that their jobs are under consideration or that their places will be eliminated. Like all businesses, our business is evaluated by us on a regular basis. This can result in increased investment in some places and, from time-to-time, re-deployment others.”

The software giant did not specify how many jobs would be cut.   Microsoft President Brad Smith had no comment Thursday when asked during a conference call about cuts.

The restructuring mostly affects the software giant’s sales operations away from the U.S. under chief marketing officer Chris Capossela, executive vice presidents Judson Althoff and Jean-Philippe Courtois. All three executives Monday notified employees of a reorganization, but didn’t mention layoffs.

Microsoft employs 121,567 people worldwide, and 71,594 in the U.S.

Microsoft shares fell 0.7%, to $68.57.

Earnings of Microsoft’s Surface computer line — they plunged 26%, dragging PC sales 7% down — undercut third quarter results while its Azure cloud revenue doubled.

The Redmond, Wash. company’s profits total soared 28 percent to $4.8 billion. Sales rose 8 percent to $22 billion.

Strong earnings made up for its drop making great on the assurance of Althoff for the Azure cloud-computing support of Microsoft are the centerpiece of the organization’s sales plan.

The shift in plan of Microsoft had a ripple effect on its own earnings, prompting a transfer to phone assistance from on-site support, states Microsoft analyst Jack Gold.

“This is not the first realignment Microsoft is undertaking as a result of change to cloud, and it is unlikely to be the last one,” Gold says.
