Microsoft counts things like Office 365 and Azure AD as “cloud.” If you look at people truly using their cloud products in terms of things that pair off against AWS offerings the picture looks vastly different.
I’ve worked with many companies recently that are broadly “all in” on AWS but still use O365 and AD as core to their infrastructure. All these surveys and studies count such companies as Azure users but in practice they’re really not. Equally the companies that are still mostly not in the cloud but use O365 and maybe Azure AD for some 3rd party app auth are also counted as Microsoft Cloud users when they’re really not.
As they say 82% of statistics are mostly made up.
Please stop repeating this. Microsoft started reporting Office 365 revenue separately from Azure revenue years ago.
Even if that was true, AWS also counts their parallel but far less complete services.
