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

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)
