A Framework for Delivering Business Value © 2008 IBM Corporation

The Justification for SOA

Business and IT Alignment– Driving IT design decisions from a fundamental understanding of

the business model to which IT is being applied

Business Flexibility– Ability to accelerate change

– Ability to deliver innovative new business functions/capabilities

– Ability to shift IT spend toward new function => reduce costs

Today’s World-Class Business**Sources: CBDi

Why SOA for Business Flexibility and Reuse?

Economics: globalization demands greater flexibility

Business processes: daily changes vs. yearly changes

Growth through flexibility is at the top of the CEO agenda

Reusable assets can cut costs by up to 20%

Crucial for flexibility and becoming an On Demand Business

Flexible business requires flexible IT

… a service?

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

open new account

What is …..

… 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



A software and hardware platform for building, deploying and managing solutions that subscribe to the SOA style of enterprise architecture

– Along with:

– Community– Ecosystem– Governance– Content– Standards

What do We Mean by an SOA Foundation?

Service-enable existing assets

1. Service-enable high-value existing IT assets for reuse2. Use externally provided services to support commodity tasks3. Fill in gaps by creating new services

Three Key Sources of Services for SOA

13



SOA Programming Model

Service Components– A technology- and language-independent representation of a service

which can be composed with other services

Service Data– A technology- and language-

independent representation of a data entity that can be passed between services

Service Bus– A technology- and protocol-

independent representation of the interconnection between services

SAPAdapter

OracleAdapter

DBAccess

DBAccess

Portlets Query

CommunityManager

Design( Models, Patterns, Templates, Policy )

Composition

BusinessComponents

InformationUser Interaction Invocation

SOA Programming Model Aspects

Composition of Business-level Applications– Wired assembly of services to form business-level

applications, workflows, and business orchestration

Information– Built-in access to service state, disconnected

service-data exchange, information composition and transformation

Business Components– Composable and reusable services

User Interaction– Dynamic support for people integration into the

business design

Invocation– Loosely-coupled call-style and event-driven

interconnection of services with built-in support for topology transparency, mediation, and brokering featuring standards-based interoperability

Design– Focus on business design modeling,

simplification, and role-based collaboration– Use of declarative policy to control execution

behavior and relationships

SOA Governance

IT Governance:Establishing decision making rights

associated with IT

Establishing mechanisms and policies used to measure and control the way IT decisions are made and carried out

SOA Governance:Intersection of Business and IT governance focused

on the lifecycle of services to ensure the business value of SOA

BusinessGovernance

SOA Governance

IT Governance

Governance:Establishing chains of responsibility, authority and

communication to empower people (decision rights)

Establishing measurement, policy and control mechanisms to enable people to carry out their roles and responsibilities

Business Services are business level "building blocks" whose execution can be adapted at runtime based on business policy and user context

CBS have Unique Attributes and Corresponding Platform Requirements

Subscribable: Platform needs to control and manage service entitlements for service subscribers

Publishable: Platform must be able to describe CBS via meta-data and publish for discovery, inspection and reuse

Composable: Platform needs to assemble CBS from services exposed from ISV, Legacy, 3rd Party, or Custom assets

Visible: Platform needs to capture business-level usage data to further optimize and adapt offerings to changing needs

Dynamic: Platform needs to dynamically select and execute services based on context, contract and content

Governable: Platform needs to manage and govern services through their lifecycle including change mgmt, access rights, and approval processes
