Service Oriented Architecture 30 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. Burton Group: VantagePoint 2005-2006 SOA Reality Check 32

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

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-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.

Buy or Build 39

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

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.

Enterprise Architecture as Strategy: 6% in Business Modularity 109 400+ Fortune 1000 companies.

Hype? 110 Well adopted hype.

Why? 111

Reduce duplication 112

Transparency 113 Who is using what information? SSN issues. Business Processes in higher level languages or models that are easy to understand.

Agility 114 Sarbanes-Oxley Act of 2002
