A Service Architecture Concept Model

IMPORTANT: This is just a concept illustration. I'm not encouraging anyone to accept and begin using the nomenclature used.

This is just the result of a conversation Tom and Ed and I had today about how this illustration might evolve. If something isn't clear, please leave a comment. If you've seen other illustrations or nomenclature about these things that better resonate with you, please leave a comment and tell me about them. If you have any other thoughts, ... I think you get the idea :)
