I stumbled upon a pretty intensive series of articles on SOA on the Oracle Technology Network written collaboratively by 8 recognized industry experts. With the authors being mostly 3rd-party (not from Oracle), the series has turned out to be very useful and not focused on Oracle products.
So far they have 6 of the 13 planned articles finished:
- Chapter 1: Industrial SOA
- Chapter 2: SOA Blueprint
- Chapter 3: Service Categories
- Chapter 4: SOA Maturity
- Chapter 5: Enterprise Service Bus (ESB)
- Chapter 6: Securing the SOA Landscape
