This is a more in-depth comparison of SOAP to CORBA than the rant I blogged earlier. It is quite sharply biased against SOAP (I’ve never been much swayed by “eeew XML is so verbose” arguments). But I think many of its points are fundamentally sound. Mike Olson also ran some SOAP/XML-RPC/CORBA performance tests on Python, with remarkable results.
