What do you know about the way Amazon runs its fulfillment and delivery network?

"Amazon has introduced many incredibly advanced supply chain management practices that have led to its domination of online retail and e-commerce offerings. From my research and understanding, Amazon outsources its inventory management tasks while insourcing logistics. Third-party sellers account for more than half of Amazon's sales, and other products that are not ordered as frequently are not stored in Amazon warehouses. The company's same-day and now 2-hour shipping service is possible because Amazon cut out third-party carriers as much as possible. Amazon primarily relies on its own delivery vehicles for these same-day shipping options. Dividing warehouses by delivery options is an important point for me to note, as well. By having different warehouses for Prime, one-day delivery, and more, Amazon can streamline its operations and prevent delivery challenges that commonly cause delays for its competitors. I am excited to learn more about Amazon's unique efforts for meeting customer needs while continually changing the way we approach logistics."
