Basically, the title of this post and its premise is just very wrong. Microsoft includes Office 365, LinkedIn and probably GitHub in its "cloud" revenue. AWS "cloud" revenue is not remotely comparable.
> MSFT: "Our commercial cloud revenue, which includes Office 365 Commercial, Azure, the commercial portion of LinkedIn, Dynamics 365, and other commercial cloud properties, was $16.7 billion and $31.9 billion for the three and six months ended December 31, 2020, respectively, and $12.5 billion and $24.1 billion for the three and six months ended December 31, 2019, respectively. These amounts are primarily included in Office products and cloud services, Server products and cloud services, and LinkedIn in the table above." https://www.sec.gov/ix?doc=/Archives/edgar/data/789019/00015...
