One thing I've wondered is how much of Amazon/Google/Microsoft's services are running on the public versions of AWS/GCP/Azure?
Very little at google runs on cloud. It runs on borg. Cloud runs on borg.
This is interesting. I've not read about this before. Any blog posts/articles you'd recommend?
I know this from working there, but it’s kind of a shameful “secret” as far as I can tell?
Considering almost everything public facing at Google supports IPv6 and almost no GCP services support it outside of a few regions (1 in the US), I’d guess none of it.
