What is the top focus of businesses?

75% of CEOs place a high or very high priority on the ability to respond rapidly

Only 1 in 10 CEOs believe that their organization has the ability to be very responsive to react to changing market conditions

Software

Traditional Business*

Today’s World-Class Business*

*Sources: CBDi

Economics: globalization demands flexibility

Business processes: changing quickly

Growth is at the top of the CEO agenda

Reusable assets can cut costs

Greater information availability

Crucial for flexibility and becoming an On Demand Business

Flexible business requires flexible IT

Why SOA for business flexibility and reuse?

Integration in an SOA World

To be easy to use a solution for SOA Integration requires

– Common Data Model

• All Data is represented consistently

– Common Invocation Model

• All components are represented consistently• All components are invoked identically

– Common Connectivity

• Enterprise Service Bus

– Service Choreography

• Components can be choreographed independently of their implementation


Software

Software

SDO – Service Data Objects (Data)


Software

The Common Data Model: Business Objects

Enhanced Service Data Object

– Provides some function notavailable in base SDO specification(close to SDO 2.0)

– Supports Inheritance and Aggregation

– Enables import of ‘standard’ XSD

Business Object Framework consists of:

Business Object Services

Business Graph definition

Business Object definition

Business Object Metadata definition

Software

The Common Invocation Model: Imports / Exports

Adapters– J2C 1.5– WBI Adapters

Web Services– SOAP over HTTP, SOAP over JMS

JMS (WebSphere Messaging Resources)– Point-to-Point and Publish/Subscribe– Integrate existing WebSphere MQ Solutions

through MQ Link

EJB

SCA– Connect modules to each other without

exposing the interface outside of WebSphere Process Server

Standalone Reference– Enables an SCA API Client to call a Module

Software

Common Connectivity: Enterprise Service Bus

An Enterprise Service Bus (ESB) is a flexible connectivity infrastructure for integrating applications and services.

An ESB powers your SOA by reducing the number, size, and complexity of interfaces.

Shape = Protocol

Color = Data type

An ESB performs the following between requestor and service

• CONVERTING transport protocols between requestor and service

• HANDLING business events from disparate sources

• TRANSFORMING message formats between requestor and service

• ROUTING messages between services


Software

ESB Mediation Component

Provide the Implementation of mediation “logic”

– “flows” that operate on messages/events as they are processed by the system

– Operate on both One-Way and Request-Response interactions

Pre-Supplied primitives allow flows to be visually composed

– XSLT Transformation

– Message Logger

– Message Filter

– Fail

– Stop

– Database Lookup

– Custom (Java) Component

– CEI Emitter (Post GA)

Software

Service Choreography: WS-BPEL

WS-BPEL provides portable, interoperable process models

WS-BPEL enables …

– Defining business processes as coordinated sets of service interactions, recursively into new aggregated services

– WSDL abstract interfaces alone used to define composition

– Defining both abstract and executable processes

• Abstract processes for e-commerce specifications• Executable processes provide a model to integrating enterprise applications

– Creating compositions of services

• Composition based on abstract descriptions

Software

Human Task Manager – Human Tasks

Three kinds of Human Tasks

– „Invoke humans as services“

• The ‘classical‘ staff activity scenario

– Allow humans to invoke services

• Services implemented by business processes or arbitrary service components

• Control which users are allowed to invoke a service

– Allow humans to „invoke“ humans

• Services „implemented“ by humans (Ad-hoc)


Software

Human Task Features

Different, rich assignment rules for Editors, Readers, Administrators and Potential Owners

Multiple Clients– Web Client– Portal Client

Multi-level Escalation Mechanisms– e-Mail– Staff Assignment -> Notification Work Item– Priority Aging


Software

Business Rules

Externalize Business Logic from an application (business process)– Easy change of logic that may change

Dynamically Update Rules in Runtime on the fly through Web Interface• NLS enabled free text representation for rules

Most-requested Business Rule Functionality– Decision Tables– Rule Sets (If/Then Rules)– Rule Templates– Action Rules

Ease of Use– Rule Group: detailed implementation encapsulated in a component with a well

defined interface

An event occurs whensomething significant happensin the IT system.

– E.g., whenever an application processes a new order or a failure occurs in a critical part of the system.

Based on CEI (Common Event Infrastructure)

Data about the event are captured in an event object.

– The event object has a standardized format calledthe Common Base Event (CBE)

– The application supplies the business data and WebSphere fillsin the details from the runtime environment such as the server name, J2EE component details and business context.

All event objects are passed to the event infrastructure to enable:– Tracking the progress of a business process– Audit trails– Coordinating work between independent business processes– Monitoring for exceptions in a business process

• For example, if the process does not complete within a time limit

WebSphere Software Platform – Tools Portfolio

All IBM Software Development platform products install in a consistent and extendable way within the ‘platform’

– First Product installs the ‘platform’ as well as it’s own product-specific ‘installable units’

User of multiple tools, experiences a single integrated “desktop” IDE

Reuse of RAD and Eclipse components (‘installable units’) is baked into the design
