Bridging the Gap between Business and IT: How?

How do I optimize my

business processes?

Business ModelsIdentify Process Activities

I/T Components exposed as SOA Services

How do I integrate to my existing systems?

Demo SOA End-2-End High Level

Business and I/T can use a

common language

a.k.a. “Process

Integration”

BusinessProcess

Activities =

I/T ServicesGranularity

5

… a service?

A repeatable business task – e.g., check customer credit;

open new account

What is Service Oriented Architecture (SOA) ?

… service orientation?

A way of integrating your business as linked

servicesand the outcomes that

they bring

… service oriented architecture (SOA)?

An IT architectural style that supports service orientation

… a composite application?

A set of related & integrated services that

support a business process built on an SOA

6

Why should IT use Service Oriented Architecture?

Organizations are composed of

People Processes they run

Information they use

7

Why should IT use Service Oriented Architecture?

8

Why should IT use Service Oriented Architecture?

Human Resources

Payroll

Accounts Payable

Time & Attendance

Organizations are Service Oriented

9

Why should IT use Service Oriented Architecture?

For the same reasons businesses are organized by services:

•Measurable and accountable

•Efficiency and optimization

•Specialization and best practices

•Well-defined interaction and processes

•Independently scalable

•Reduce duplication and reuse assets

• Isolation of changes

As Patterns Have Evolved, So Has IBM

Flexibility

Point-to-Point connection between applications

Simple, basic connectivity

Messaging Backbone

EAI connects applications via a centralized hub

Easier to manage larger number of connections

Enterprise Application Integration (EAI)

Integration and choreography of services through an Enterprise Service Bus

Flexible connections with well defined, standards-based interfaces

Service Orientated Integration

SOA builds flexibility on your current investments The next stage of integration

Applications can be composed of or exposed as services
