I've never sat down to do the mapping, but I'm pretty sure almost all the networking concepts and modules in AWS have a more or less direct counterpart in GCP.

I've never sat down to do the mapping, but I'm pretty sure almost all the networking concepts and modules in AWS have a more or less direct counterpart in GCP. Which is not surprising, because most of them also have a direct counterpart in networking standards themselves. They're both essentially just views into the world of software-defined networking.
