> Google, being an ad giant

Isn't Google also a cloud giant?

I wouldn't say so. They're not offering their cloud at the same scale other competitors. Not sure when the last was I saw advertising for unlike AWS, Azure.

Felt more like their cloud services were more of a side product for when "the cloud" was the trendy buzzword and a way to justify their infrastructure costs. That and keeping a leg in the egg & spoon race.
