My guess is that the majority of Amazon's web services access will follow [the REST] route. I hope this doesn't further polarize the REST/SOAP situation, though. The simple, query-oriented APIs that Google and now Amazon have offered are not really a fair test. Partner interfaces that require more complex two-way exchanges, whether in RPC format or document format, are the province of SOAP. These by their very nature are harder to make accessible to experimenters. So let's enjoy the RESTful aspect of Amazon without jumping to broad conclusions. [Jon Udell's weblog]
Jon Udell posted an experiment with the REST (XML over HTTP) Web Service interface to Amazon and a thoughtful reply. Jon's articulate anti-extremist views are always worth reading and noting.
