Pragmatic SOA Interoperability

Jesus Rodriguez and Javier Mariscal, @ SOA WORLD MAGAZINE. A well-planned Web Service interoperability environment begins by clearly defining who your Web Service consumers are now and in the future. There was a time not so long ago when you could count on a fairly homogenous consumer population. This was about the same time that you were happy just to be able to get a Web Service running in the first place and finding a consumer who could actually interact with your Web Service was cause for celebration. Those days have changed however and Web Services interoperability, once a "fancy" addition to your SOA design, is now a key and indispensable requirement in most SOA scenarios.
