What is SOA ?

Integrating Applications are process-oriented systems built “on top of” multiple existing systems.

How are Composite (Integrating) Applications different?

The “Good Old Days”• 1 mainframe computer• 1 user device• 1 network connection• 1 population of users• 1 set of user requirements• 1 user location• 1 program• 1 program “owner”

Composite Applications• Many computers• Many user devices• Many types of network connections• Many diverse populations of users• Many different user requirements• Many user locations• Many programs• Many program “owners”

How do Composite Applications deliver business value?

28

How Composite Applications Deliver Business Value

• Reduce personnel costs by automating process steps

• Reduce requirements for highly skilled decision-makers

• Decrease the frequency of “wrong decisions”

• Reduce process latency

• Track execution of multi-step processes to ensure process efficiency

• Track results of processes (through Business Activity Monitoring) to enable realtime process enhancement

• Automate some exception handling

• Thoroughly monitor and manage processes for compliance purposes

What is the Business Value of an SOA?

37

Composite Applications are built “on top of” existing data and applications.

The standards used when building SOA deliver the benefits of Loose Coupling

• The concept of “Loose Coupling” can be explained by looking at a fan that is plugged into the wall blowing air into another fan which is unplugged.

• The air from the powered fan “pushes” the unplugged fan until the speeds of the two fans are almost the same.

• But, because of this Loose Coupling between the fans, if you quickly stop the unplugged” fan, the powered fan will go on turning as before. Nothing is broken.

• Similarly, Loose Coupling between programs allows one program to be changed without breaking the other program.

An SOA provides for Loose Coupling between service

consumers and service providers.

42

This Loose Coupling, in turn, supports Application Rationalization.

An integrated toolset reduces costs throughout the system development lifecycle.

• Advantages of a single repository – Better support for reuse.

– Better support for impact analysis.

– Better support for version control and configuration management.

• Advantages of a single runtime– A single management framework.

– A single security framework

– A single transaction management framework

– A single debugging environment

• Advantages of a single development environment– A consistent look and feel

– Reuse of development tools

• Standards Support for Interoperability and Portability



62

Using Web Services to deliver true Plug-and-Play Interoperability

• Project Tango – Sun and Microsoft collaborate on a set of Web Services standards

• Microsoft’s implementation of this stack is in Windows Communications Foundation (formerly “Indigo”)

• Sun’s Java implementation is on the recently introduced, open sourced Web Services Interoperability Technology (WSIT)

• Economic coercion will ensure adoption by all major vendors

Going forward:−Everyone will need to provide

“certified” interoperability with WCF−Everyone will need to provide

“certified” interoperability with WSIT−Plugfests will be the “certification

mechanism” to ensure compatibility

63

Portabilty Between JBI-based ESBs

Java Business Integration (JSR 208) provides a standard so components can plug into an ESB.

Model Driven Development

With Model Driven Development, a diagram . . .

. . . becomes 100 pages of code.

This significantly shortens development time and reduces development costs.

Model Driven Development reduces programming and maintenance costs for Composite Applications.

Reduce the number of hours required to build a service by 25-43%.

Reduce the cost of maintaining that service by more than 25-43%.
