Excerpt from a cloud market dynamics snapshot
"Microsoft ranks a distant No. 2 in cloud computing. It is hard to precisely compare the two businesses because of how Microsoft reports its cloud results.

Microsoft, though, also includes revenue from different online applications into that figure. Its revenue from a cloud business called Azure, which is more directly comparable to Amazon’s cloud services, was recently estimated by Deutsche Bank to be as little as one-tenth of that from AWS."
