Want to charge users to access your data, instead of incurring the cost yourself? Amazon has introduced "Requester Pays", which allows data owners to charge the accessing party for all data transfer and request costs. This is a fantastic business model innovation. Jeff Barr at Amazon correctly believes that business model innovation is as important to technical innovation in the SOA world. His vision gives businesses more motivation to switch to SOA. Requester Pays opens Amazon's platform to a new class of data based services.
