In this presentation, recorded at QCon London 2007, Amazon.com CTO Werner Vogels explains how Amazon has become a platform provider. According to Werner, Amazon.com has undergone the transformation from application to platform provider, and although Amazon.com's scale makes them seem an extreme case, lessons have been learnt that will be of use to every enterprise looking to provide services to or to consume services of business partners.
From an SOA perspective, it is interesting to note the degree to which Amazon.com has adopted a pragmatic approach to service-orientation, with a service as a cohesive unit of data and logic. According to Werner, there is a single team per service – without any "virtual wall" between development and operations.
