5. Definition of SOA (by The Open Group’s SOA Work Group)
Service-Oriented Architecture (SOA) is an architectural style that supports service orientation
Service orientation is a way of thinking in terms of services and service-based development and the outcomes of services
A service:
Is a logical representation of a repeatable business activity that has a specified outcome
Is self-contained
May be composed of other services
Is a “black box” to consumers of the service

6. The Impact of SOA on Business
What SOA Is and Is Not
SOA is:-
A style of architecture
It can be applied to architectures at many different levels
Business architecture
Information Systems Architecture
Infrastructure architecture
SOA is not:-
An IT system (although systems can be created in accordance with the style)
A product
Always the best solution

8. Some Basic Principles of SOA
A successful implementation based on SOA will impact all of the architectures
Collaboration will be required between those responsible for each architecture
The impact of SOA on the Business Architecture is the most visible
The impact on other architectures may be greater, but is less easy to visualize
There have to be standards if SOA is to succeed
Even at the business level
These are mainly corporate or industry standards

10. The Current Status of SOA Standards
An abundance of SOA open specifications and standards from OASIS, OMG, W3C, The Open Group, etc.
A joint document “Navigating the SOA Open Standards Landscape Around Architecture” published July 2009 by OASIS, OMG and The Open Group
It explains and positions architectural standards for:-
SOA reference models and ontologies
Reference architectures
Maturity models
SOA modelling languages
Open standards related to SOA governance
Outlines agreement on core SOA and SOA governance concepts
The work goes on

12. The DDB Group (an imaginary business)
Was formed in 1882 as the Dursley Drill Bit Company
Succeeded due to quality and patented processes
Has grown world-wide by acquisition of other companies
Each acquisition had own production processes that must be retained due to their speciality and excellence
Now produces hi-tech drill bits, cutters, routers, grinders and millers for the machine tool industry
Operated as a loose collection of semi-autonomous specialist companies
