As another commenter mentioned, MS' customers are running Ubuntu on Azure en masse. So it's mostly a risk mitigation and "owning the platform end-to-end".

Maybe it's because I don't know the field, but I don't see a he risk yet. I mean does AWS own its own OS? It's a standard OS, what can go wrong?

Yeah they have Amazon Linux which is their own fork of Red Hat Enterprise Linux.
