Microsoft engineering groups

Microsoft engineering groups are the operating divisions of Microsoft. Starting in April 2002, Microsoft organised itself into seven groups, each an independent financial entity. In September 2005, Microsoft announced a reorganization of its then seven groups into three. In July 2013, Microsoft announced another reorganization into five engineering groups and six corporate affairs groups. A year later, in June 2015, Microsoft reformed into three engineering groups. In September 2016, a new group was created to focus on artificial intelligence and research. On March 29, 2018, a new structure merged all of these into three.

As of 2023, there are four groups:


 * Cloud and Artificial Intelligence (Azure, GitHub, Visual Studio, npm, C#, .NET, TS)
 * Experiences and Devices (Windows, Microsoft 365, Outlook, Teams, Bing, Edge, Surface, HoloLens)
 * Gaming (Xbox, Xbox Game Studios, ZeniMax Media, Activision Blizzard, Game Pass, Cloud Gaming, Xbox network)
 * Technologies and Research (Garage, M12, Microsoft Research)

Experiences + Devices
This group produces consumer and enterprise experiences, spanning from Windows products and devices to Microsoft 365 productivity subscription solution. Experiences and Devices is led by Rajesh Jha; Windows and Devices is led by Panos Panay; Office Product Group is led by Joe Belfiore; Web Experiences and Advertising is led by Mikhail Parakhin.

Microsoft underwater data center
In 2016, Microsoft made plans to operate an experimental underwater server farm off the coast of Orkney. The nitrogen-atmosphere enclosed server farm was actually moved into position under the sea in May 2018, and included 855 servers. Powered exclusively by electricity from the Sun and wind, the server farm operated for two years, until May 2020, when the experiment ended, the enclosed tube was recovered, and brought to the surface for analysis. Preliminary results showed only 8 of the 855 servers failed during the two-year test, a failure rate of just 1/8 that of Microsoft's above ground server farms.

Technologies + Research
This group was created in September 2016 to emphasize the company's presence on artificial intelligence. It was formed when parts of the former Apps and Services group came together with the research team to form a fourth engineering group. Led by Harry Shum.
