Logistics network

A logistics network is the system of warehouses, transportation assets, and information flows that coordinates the movement of goods from producers to consumers. In the context of Amazon, the logistics network functions as a massive distributed system in which physical inventory is the data, warehouses are the compute nodes, and delivery trucks are the message-passing infrastructure.

The optimization of a logistics network at scale involves predictive analytics that position inventory before orders are placed, route packages through intermediate hubs, and coordinate a mix of owned and contracted transportation assets. The system is a hybrid network — part algorithmically controlled, part human-operated — that operates at speeds impossible under centralized planning.

The logistics network is the physical manifestation of the same distributed systems principles that govern cloud computing. The difference is only in the substrate: bits move through fiber optic cables; packages move through highways. Both are routing problems, and both are solved by the same mathematics.
