SOAは誰がころしたのか?

»

以下は最近、海外のメーリングリストでサービスの定義に付いての議論である。正論としてサービスはこのように定義するべきだっと言うのはよいと思うが、実際にその定義で実装できないと言う。これでよいのか?

I'm designing them in this way but unfortunately in implementation there isn't the technology to support this stuff.  WS-Contract or WS-SLA never happened and there isn't anywhere near the formalism required.

I think you've hit the major difference we're having. I'm in an actual project and tailoring my service so they can actually be implemented with the current available technology, development members, and other constraints. Also, with the economic slow down, it is also necessary to reduce cost.

There was a mention of BPEL in the other thread, and I think the basic technology is interesting, but the current situation requires too knowledge of too many specifications that it almost impossible to educate development members to complete a project in time. Of course, in a small project, I can just do it myself but in a large project, that's impossible.

SOA is dying not because the theory behind it is bad, but that what most people are preaching can not currently be implemented in a project. The tight economy is also sifting the emphasis from "to be" more toward  "can be".

Anne's cartoon showed a "SOA dinosaur", but IMHO the dinosaur really isn't the concept of SOA itself, it more of us who's not adjusting to the current economic market.

Happy Holidays,
