Carnets de BordA weblog about Service Oriented, Process Centric, Model Driven Programming ModelsREST Who Said Uniform Interface- April 30, 2008 These days, Tim Bray courageously claims "REST, they say, is the way to go". I guess if "they" say, it must be true, as long as Tim repeats it. Francois Leygues, a French member of the REST community, sent me a pointer to this blog post from Andrew Townley: "URI Opacity Revisited". Andrew's findings are in line with mine when it comes to explaining how "uniform" an interface can be. Yes, when a human is in the loop,..http://www.ebpml.org/blog/82.htm OTHER Where's your DVD drive- April 29, 2008 This video caught my attention. So its the Spring of 2008, you are the CEO of 60+ billion dollar ISV and when someone shows you an Air Book, you ask where's your DVD drive I am surprised he did not add, where's your modemhttp://www.ebpml.org/blog/81.htm SOA Can't wait to get Webberified and Savastisized- April 27, 2008 I am seu scared, I think I am going to go duck under by bed, ney, I am from Marseilles (Remember Zidane) with roots in Porto-Vecchio, and I did live in my youth in the North Quarters (Boulevard Jourdan Prolong to be exact), so I learnt a thing or two there. Steve, thanks for the post, I had such a good leugh. Frankly, never have I seen a post as crapy as Jim's (that being said, I do feel a bit less bad, now that you said this). This one from Jason Woodruff is for a good laugh too, I am...http://www.1060.org/blogxter/entry?publicid=B9AACBD579F0128C2B59697F2CB34F7F SOA Dave Thomas on SOA- April 27, 2008 Dave is a pretty cool guy. I think he has a point about SOA standards, however, I have lived quite a few years in the Technical Commitees and Working Groups of the SOA standards at W3, OASIS and OAGIS. I can tell you that the John Yunkers, Dale Mobergs, Monica Martins, John Evdemons, Eric Newcomers, Mike Edwards and Jim Marinos of the world (and many many more) worked their a... off to get great stuff out the door. There is a lot more personal politics (driven by substandard thinkers more...http://www.infoq.com/interviews/dave-thomas-programming-languages-soa-and-the-web SOA What's Cohesive About SOA- April 26, 2008 Some people tend to think that I enjoy creating such a controversies, but at the end of the day I don't. Anybody is of course free to say and do what they want, but we seem to have reached a point of evolution that seem to imply "as long as you can say or write something, there is always some truth to it". SOA could very well be the ideal area to say anything you want. And boy do some people enjoy doing that. Of course, you could very well turn this...http://www.ebpml.org/blog/80.htm SOA Is SOA about building distributed systems- April 24, 2008 Stefan commented that "respected members of the distributed computing community for a long time" had to be right about SOA and I had to be wrong because I was a lonely voice. First, I am not alone, we are simply not as "cohesive" as certain groups. Even saying "we" sounds weird to me. This is not about we, us, them. This is about SOA. What I am often arguing about is well supported by commercial products and open source...http://www.ebpml.org/blog/78.htm SOA Composite Applications, Service Oriented Architecture and ESBs Issues and Decisions- April 23, 2008 This is a good high level presentation from Ross Altman (Sun Microsystems) on Composite Applications. The statement I have a bit an issue with is that: "Most ESB Suites also provide technology to deliver Composite Applications on top of those services". For me, an ESB is a service container that offers great "technical services" to construct services that can participate in a composite application. With JBI offering an assembly model, you can also think that ESB's can play that role...http://www.omg.org/docs/soa-c/08-03-01.pdf SOA Cohesive Response- April 22, 2008 Well I got a lot of people upset: Stefan, Savas, Jim kept the legendary British cool. Again, I stand by what I am saying, Jim's position on: cohesion in SOA (beyond the trivial conclusion that any autonomous asset is by default exhibiting a high degree of cohesion) process-to-service relationship MVC as a design pattern for SOABPM Business people becoming IT architects (last but not least by far) is more than questionable. Savas,..http://www.ebpml.org/blog/77.htm SOA Loose coupling and Cohesion- April 22, 2008 Quite hilarious (and symptomatic), I advise Jim to catch up with modern SOA concepts, technologies and principles and he advises me to read antiquated software engineering books, or articles from Steve Vinoski. Jim, if all you wanted to tell us is that autonomy requires some degree of cohesion, well you did not need a blog post for that. I was trying to interpret your blog post in the context of an assembly of services performing a unit of work and wondering...http://www.ebpml.org/blog/76.htm SOA Loose coupling- April 21, 2008 A couple posts picked my interest today. "Does WOA bring anything new to SOA" by Mike Meehan. Well, I have already expressed what I thought about WOA and REST so I won't do a repeat here. What I found surprising is that there is actually quite a few people agreeing with some of what I was saying. If users perceive WOA to be outside the principles of SOA, it could prove an excellent vehicle for building Web-based stovepipes. The article...http://www.ebpml.org/blog/75.htm |
