So, there's a thing I wonder about cloud businesses, Amazon or anyone else's. How much of this is funded by businesses that are not profitable, but are running on VC money? I recall the IPO documentation for companies like Uber stating a stupendous amount of their $$ going for AWS. I am reminded of Paul Graham's description of Yahoo's advertising business in 1999. Lots of paying customers, things seem great, you're solidly profitable. But what if most of your customers aren't profitable? What happens when the next recession comes? Not saying cloud computing is going away, but I think its current apparent growth rates are being propped up by a lot of Softbank (and similarly unprofitable) investments, which will go away fast when the next recession comes. Until then, we don't really know how profitable cloud computing is as a business. It may not be as good as it looks right now.
