Service Oriented Architectures (SOAs) intentionally mixes technology, standards, and application around the idea of service orientation to build large systems.

Change Control Coordination Accounting Workflows Reliability Lifecycle Security Testing SOA Core
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
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
Non-Functional • Improve execution environment • QoS • QoE • Reliability • Dependability • Scalability • Security • Performance
