http://msdn.microsoft.com/architecture/industry/finservs/banking/ has quite a bit that alot of banking architects would be interested in. The ones I found interesting are
- The Global Bank scenario - about designing, developing service oriented application. This gaves a strong overview of why you need a SOA to move forward. (There is also a video on the front page)
- IFX service orientation Study for payment processing (this one even comes with a demo) - financial interexchange standard. I would advise any banking solutions architect serious about SOA to read this document.
These both will have immediate impact on any adapting organization. Bon Apetite!
