Not agreeing with GP but the capacity of their public clouds is very different from total capacity. Amazon and Microsoft have bigger public clouds, but Google's own workload is probably bigger than anyone else's or even the public clouds by a large factor.
> Azure is the second largest cloud provider, well ahead of google.
I explicitly mentioned the "web", as in, what we're doing right now on this website. Leaving aside the fact that Azure is mostly used big corporate/government entities, there's no web-startup that will potentially dominate the web and that would go into Azure just as.
