SOA Core
The minimal concepts needed for SOA Aspects (Technology, Standards, Application) A set of uniquely identifiable, independent, executing
processes which interact only by exchanging messages Message system (encoding, transport, transport error
handling, message format, only handles point-to-point messages)
Service orientation- roles: consumer, provider (client, server), any process may
perform both roles- A service is what is provided by a provider
11Nathan Kerr, University of Kaiserslautern
Functional
Extend the core ideas, but do not fundamentally change them
workflows (define consumer roles) service descriptions (define provider roles) transactions choreography (should be handled by messaging) registry (binding, discovery)

Management
How to organize and manage a SOA
monitoring accounting design processes best practices life cycles deployment
