Service Oriented Architecture

as our Design Style
Define SOA
31
Not just a decision for this app. SOA as strategic direction.
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
design style - not a technology. not a set of apps that you buy from Software-R-Us
Technology
34
It is not a technology. You deploy SOA using technology but SOA is the design philosophy.
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.

Point-to-PointWeb 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.

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

Enterprise Maturity
65
Enterprise Maturity to understand what are the business objects that should be made into services. And an understanding of the breadth of their use.

19% “cohesive and functional...environment that leverages SOA...”
108
40% said they are in initial phases of deploying composite apps. Which means they have the infrastructure in place.
