If Google is using GCP internally, then their infrastructure is as you said. The GCP "best practices" sections in the docs* have been top tier in my experience and you can learn a lot, even if you're using AWS or Azure. * my one complaint is that searching for the docs almost always ends you up on marketing pages, which you then have to find the docs link on.
