Learning from the Amazon technology platform
Incredible interview with Amazon's CTO - must read to understand the transformation an SOA platform can bring to a business.
Amazon.com started 10 years ago as a monolithic application, running on a Web server, talking to a database on the back end. This application, dubbed Obidos, evolved to hold all the business logic, all the display logic, and all the functionality that Amazon eventually became famous for: similarities, recommendations, Listmania, reviews, etc. For years the scaling efforts at Amazon were focused on making the back-end databases scale to hold more items, more customers, more orders, and to support multiple international sites. This went on until 2001 when it became clear that the front-end application couldn't scale anymore.
