I didn't think there was much dispute -- this is the programming way, the CORBA and DCOM way, to access remote applications. It works well on LANs, so there's a solid base of experience to draw on that you can hide the network behind an RPC. It makes a lot of intuitive sense -- SOAP-RPC as a neutral wire format, WSDL as a neutral IDL, UDDI as a directory service. It has a plausible business model: vendors compete on ease of use and quality of implementation rather than on basic protocols. I can agree with the REST people that it's not "the Web way", that it forces a reinvention of things that the Web already supplies, and that it may not scale to the web as it really exists... but I understand why the Web Services people chose the "programming way" and treat the Web as simply a giant LAN. We shall see if it works out that way. I'll predict that both win: Traditional RPC really is the easiest way for programmers, and will work well enough behind firewalls and between established partners and in arenas where user simplicity matters more than system reliability (e.g., for Userland's typical customer, AFAIK). But now matter how fast the Internet that we know today improves latency, reliability, security, etc., it will be extended geographically and to smaller and more mobile devices,continually opening more niches where the REST paradigm shines. The only "REST rules, RPC drools" scenario I can imagine, i.e. that would make the WS tool vendors' inital focus on RPC ill-considered, is if the non-programmers somehow grok REST big time and find it an easy migration path from what they do now to the Wonderful World of Web Services. It's more likely than assuming they will learn to think like a programmer, no? Will non-programmers build and use web services? Maybe not, but who would have thought 10 years ago that the average student, office worker, etc. would have a basic knowledge of a markup langugage (HTML) today?
