> They should also have included oracle which will soon surpass google (making it 5th most popular) cloud

I seriously doubt it. Only companies already heavily invested in Oracle are taking their offering seriously. They are pretty late to the party.

Surely, if we were including other clouds, we'd include IBM before Oracle... :))

I would add Alibaba Cloud before them too :)

Oracle's cloud is an also-ran. Just follow the investment the cloud giants are making. Oracle is not even in the same league. From:

https://www.platformonomics.com/2019/02/follow-the-capex-clo...

"Google’s incremental CAPEX spend in 2018 is about what cloud pretender Oracle has spent on CAPEX throughout their entire history."

Sure, and I'll just patch together a few of my home PCs and we can call that a cloud too

What rankings are you referring to?
