There is search, Adsense, gmail, google docs and Gemini. Do they at least train Gemini on GPUs on GCP?

maps is another big one.

one of the craziest comments i've read on HN. google does a lot of internet things these days, idk if you've been out of the loop for a while

I didn't express it well.

Google's consumer-facing systems all tend to be very focused. Things like search, maps, gmail etc. are not the same kind of system as Amazon's store.

While these systems do presumably give Google something to exercise their cloud systems on, the sense I have (as a longtime user of both GCP and AWS) is that it doesn't give them a realistic sense of what other companies, that don't just sell advertising and consumer data via focused products, do. Amazon's store is more representative of typical businesses in that sense.

Basically, it seems to me that Google Cloud has continually learned lessons the hard way about what customers need, rather than getting that information from its own internal usage.
