I worked NA logistics back when I was with Amazon, and was with the team behind the LA fresh and the team which works with intermediate FCs (they don't stock goods, but do store-and-forward at crucial locations in the logistics pipeline). And you are right, Amazon does an incredible amount of stuff when it comes to logistics. There is an entire building that houses trans & metrics team, and the hyderabad center in India is mostly just the transportation team.

Amazon is way ahead in the logistics game, even further than some of your flagship logistics companies.
