Last week, at the International SOA Symposium in Amsterdam, Thomas Erl launched two new books which I think are a must read for any serious SOA practitioner. The first one to be launched was Web Service Contract Design & Versioning for SOA, which I've started reading already. It's a massive book (again), but so far I'm impressed. Easy to read, good examples, definitely worth the time reading it.
I'm even more eager for the second book that was announced: SOA Design Patterns. Unfortunately this book is still on its way from Amazon to my home, so I cannot give any insights, but I do expect a lot from it. As Thomas explained during his presentation at the International SOA Symposium, it consists of 85 real-world, real-practice design patterns. One of the nice things with this book is, that there's a website along with it, containing all the 85 design patterns, but also the candidates that didn't make it into the book. If you have a design pattern you think should be in the book, publish it on the site, and maybe it'll be in the next release ....
