I doubt this - Walmart have scale, experience and infrastructure over Amazon but what they're lacking for in these areas, Amazon more than makes up for it in engineering culture. Amazon is first a foremost a data-driven company. Companies say this so much that it's now a cliche, but you better believe it with Amazon. As an exclusively online (until recently) retailer, every single sale goes through their data warehouse. Every single product, price, clicks are all stored - think of the analytical capability of that consolidated store of data. Amazon is probably the singly largest reserve of economics data. Moreover, I am fully certain every one of their products, cars, trucks, planes and even people are hooked up into real-time tracking. When you have that much data all centralised, and the scale of Amazon, real life problems start to resemble CS problems and Fulfillment Centers and logistics start resembling CDNs. If only Amazon has extensive knowledge of the workings of CDNs... oh wait.
