> To me cloud provider in this context means a vendor that provides cloud platform for others to develop on top of. RDS counts, Office doesn't.

I completely agree with you on this one.

However all the cloud providers include their SaaS subscription services revenue in cloud revenue. So when comparing market, revenue and stocks, that's what we should compare them on. But here we are in this thread looking at their "cloud revenue" to figure out which is a bigger "cloud vendor". That's like comparing Apples and Oranges.
