as our Design Style

31. Define SOA
31
Not just a decision for this app. SOA as strategic direction.

32. Service-oriented architecture (SOA) is a
style of application design that focuses on
implementing software functionality as
shared, reusable services, in which each
service represents a relatively autonomous
business or technical function.

33. Service-oriented architecture (SOA) is a
style of application design that focuses on
implementing software functionality as
shared, reusable services, in which each
service represents a relatively autonomous
business or technical function.
Burton Group: VantagePoint 2005-2006 SOA Reality Check
33
design style - not a technology. not a set of apps that you buy from Software-R-Us

34. Technology
34
It is not a technology. You deploy SOA using technology but SOA is the design philosophy.

35. Application Stack
35
Not a suite of Applications you buy from (insert your favorite vendor here). The suite of
application may help you deploy and manage your Architecture.

36. Service-oriented architecture (SOA) is a
style of application design that focuses on
implementing software functionality as
shared, reusable services, in which each
service represents a relatively autonomous
business or technical function.
Burton Group: VantagePoint 2005-2006 SOA Reality Check
36

37. Point-to-Point
Web Services
37
If you replace all of your flat-file transfers with point-to-point, single use Web Services, you
are missing the point of SOA. Reuse and sharing are where people hope to gain ROI.

38. Service-oriented architecture (SOA) is a
style of application design that focuses on
implementing software functionality as
shared, reusable services, in which each
service represents a relatively autonomous
business or technical function.
Burton Group: VantagePoint 2005-2006 SOA Reality Check
38
Each service represents a business function or technical function.

39. Buy or Build
39

40. Matures
40
Not something that is built, more something that Matures. Talk more about this in a few
minutes.

41. Service-oriented architecture (SOA) is a
style of application design that focuses on
implementing software functionality as
shared, reusable services, in which each
service represents a relatively autonomous
business or technical function.
