I am currently studying for the first module of the 5 module certification traject for becoming a SOA Certified Architect.
What I like about the traject is that you have the option to go to workshops or order self study kits. The workshops can be followed also at the SOA Symposium in Rotterdam in october 2009.
Furthermore the exams are based on the books of Thomas Erl a respected author in the SOA field.
I have ordered the self study kit and it took a couple of weeks to arrive. It contains two reading materials, one handout of the presentation (fortunately with an audio CD) and one what to study and example questions (unfortunately just three). The audio CDs are a pain to listen to. It looks like generated from text with hardly any tonations.
The best way for me was to read the SOA Principles of Service Design book. Tomorrow (4 sept 2009) is my exam for this first module. Keep you up-to-date about the level required.
What I am curious about though is how this certification is seen by customers. Has it reached the image of the Java certifications for example yet? That still must be seen, i guess.
