24 Case Study SOA A set of services An architectural style A set of architectural principles and patterns A programming model - tool 23

25 Case Study Service Architecture is more expensive in the beginning, but cheaper in the long run 24

26 Case Study How do you do it 1 Use a reference architecture to create your AS-IS 2 A vision is mandatory 3 SID provides a framework for logical application architecture 25

27 Case Study Create a To-Be Service Oriented Architecture 26

28 Case Study Do your Roadmap 27

29 Case Study Need a architecture method to do this 28

30 Case Study Use conceptual service framework to create the service architecture 29
