Except that they don’t. The API mandate gets violated all the time. And no one at Amazon actually treats every other team as a 3rd party.

Have you worked at Amazon?

I am not saying they treat every other team as a third party. I am saying they treat the code itself as a black box with well defined interfaces. They aren’t reaching in to another services data store to retrieve information.

How do you know someone is ex-Amazon ? Don’t worry they’ll tell you.

I haven’t mentioned it 5 times already so you can be pretty sure I haven’t. I know too many people that have worked there to ever make that mistake.

But more importantly, have you worked there in the last decade?

Then you have know idea how Amazon works. I was there from 2020-2023z.
