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.

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.

style of application design that focuses on
implementing software functionality as
shared, reusable services, in which each
service represents a relatively autonomous

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.

Each service represents a business function or technical function.
