Middleware MattersSteve Vinoski's WeblogCode-first services- December 20, 2006 Most people who have been around distributed systems development for awhile recommend against code-first services. These are services where someone writes a normal programming language artifact, usually a Java or C++ object, and then turns it directly into a distributed service. Among the reasons to avoid this are that such objects are not designed to deal with distributed system issues, such as partial failure, and also because the approach more easily allows language-specific features to...http://blogs.iona.com/vinoski/archives/000429.html Coupling isn't so black and white- December 19, 2006 Dan Pritchett takes issue with Pete Lacey's characterization in his InfoQ interview of web services being too tightly coupled. Dan's issue seems to be that REST is more tightly coupled than its proponents would have you believe. He writes: The simple facts though is that REST doesn't make this any better.

Markus has just posted the interview as a podcast. I enjoyed this interview more than most because Markus asked such a broad range of questions, rather than just narrowing in on whatever the topic of the day might be. His questions covered the whole range of my career in distributed computing, from pre-CORBA distributed systems all the way through to my current work on Qpid, and it was...http://blogs.iona.com/vinoski/archives/000421.html Celtix Enterprise: so far, so good- December 5, 2006 Stefan Tilkov has written a nice article describing our new Celtix Enterprise release. The response to our announcement so far has been pretty good, with a few hundred downloads over the past 24 hours. My own little contributions here are in the CXF dynamic language support, which I originally designed and wrote for the Celtix open source project but which has now moved to CXF, and in Qpid, the Apache Incubator implementation of AMQP, where I'm a committer. Don't let the "ESB" label scare...http://blogs.iona.com/vinoski/archives/000420.html |
