Service orientation is a means for building distributed systems... : Service orientation is a means for building distributed systems... At its most abstract, service orientation views everything—from the mainframe application to the printer to the shipping dock clerk to the overnight delivery company—as a service provider... Service providers expose capabilities through interfaces. Service-oriented architecture maps these capabilities and interfaces so they can be orchestrated into processes The service model is "fractal": the newly formed process is a service itself, exposing a new, aggregated capability.

Så hur passar objektorientering in ? : Så hur passar objektorientering in ? Object Orientation
Assume homogeneous platform and execution environment
Share classes, not schemas
Assume cheap, transparent communication
Are linked: Object identity and lifetime maintained by infrastructure
Typically require deployment of both client and server in sync
Are easy to talk about and become a natural path for customers to follow
Customers have 20+ years of experience and great intuition about what “object oriented is” Service Orientation
Assume heterogeneous platform and execution environment
Share schemas, not classes
Assume variable cost, explicit communication
Are autonomous: Security and failure isolation are a must
Ease “continuous deployment” of client and server separately
Builds on ideas from component software, distributed objects, and MOM
Dominant theme is to manage/reduce sharing between services
Objektorientering är här för att stanna !

Vad är SOA för Microsoft? : Vad är SOA för Microsoft? An approach to building systems using autonomous services which adhere to the 4 tenets of Service Orientation
Boundaries are Explicit
Services are Autonomous
Services share schema and contract, not class
Service compatibility is determined based on policy Tenet \Ten"et\, n.
Any opinion, principle, dogma, belief, or doctrine, which a person holds or maintains as true. Source: Webster's Revised Unabridged Dictionary, © 1996, 1998
Tenet 1: Boundaries are Explicit : Tenet 1: Boundaries are Explicit You know where the boundaries are
Crossing service boundaries can be costly
Consciously opt in to SOA
Explicit message passing
Agnostic to platform, middleware, language choices
Tenet 2: Services are Autonomous : Tenet 2: Services are Autonomous Services in a system are deployed, managed, versioned independently
Topology of a system evolves over time
Services expect to run in the wild
Consuming apps can and will fail
Without notice or notification
Mitigate with transactions, queues
Assume probability of malformed or malicious messages
Require signing, authentication
Use trust relationships, not logins
Tenet 3: Services Share Schema and Contract, not Class : Tenet 3: Services Share Schema and Contract, not Class Services interact solely on
schemas for structures
contract for behaviors
Contracts and schema remain stable over time
Ergo, schema and contract must be flexible
Tenet 4: Service Compatibility is Determined Based on Policy : Tenet 4: Service Compatibility is Determined Based on Policy Structural compatibility (what we’ll say) separate from semantic compatibility (how we’ll say it)
Services express capabilities and requirements in terms of a machine readable policy expression
