IBM SOA Foundation

Software

Skills &Support

Leveraging existing IT Infrastructure

Introducing the IBM SOA FoundationProvides What You Need to Get Started with SOA

Supports complete lifecycle with a

modular approach

Extends value of your existing investments,

regardless of vendor

Scalable; start small and grow as fast as

the business requires

Extensive business and IT standards

support; facilitating greater

interoperability & portability

Software



WebSphere Process Server:Process layer builds on WebSphere ESB and WebSphere Application Server

foundation to deliver robust business process management

WebSphere Process ServerLeveraging infrastructure services from WAS ND

Use WebSphere Process Server when you need to automate business processes that span people, workflows, applications, systems, platforms, and architectures

Support for all styles of integration, including human tasks, roles based task assignments, and multilevel escalation.

Business rules, business state machines, and selectors to dynamically choose interface based on business scenarios

Change business processes on the fly with relatively minimal skills

WebSphere Application Server Transport layer foundation provides infrastructure

via JMS 1.1, HTTP, IIOP

WebSphere ESBMediation layer builds on WebSphere Application Server

foundation to provide intelligent connectivity

WebSphere Application Server Network DeploymentBuilds on WebSphere Application Server foundation to deliver ahighly available transaction engine with advanced performance

and management capabilities

7

Software



WebSphere 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

8

Software



WS-BPEL 2.0

Industry standard language for expressing business processes– Leverage a common skill set and language

Designed to fit naturally into the Web services stack– Expressed entirely in XML– Uses and extends WSDL 1.1– Uses XML Schema 1.0 for the data model

Portable across platform and vendor– Will run on any WS-BPEL-compliant engine

Interoperable between interacting processes– Layering on top of Web services stack

WS-BPEL is a Recursive Aggregation Model for Web Services Stateful conversations and lifecycle management

– Supports multiple stateful long-running conversations

Recoverability– Long running business processes need fault handling and compensation

mechanisms to manage and recover from errors

Software



WebSphere Integration Developer Assembling composite applications with ease

Streamlining process design hand-off between business and IT– Import and work with business process models directly from the business

analyst (WebSphere Business Modeler)

Simplifying and speeding composite application development– An Assembly Editor for overall solution assembly– All the tools you need for building solution components (Editors for BPEL,

Business Rules, Business State Machines, Interface Maps, …)– One, easy-to-learn end user interface based on Eclipse

Architected for reuse and flexibility– Simplified

componentinterfaces

– Plug-and-play solution components

– Ability to leverage existing services and develop for future reuse

12

Software



WebSphere Integration Developer BPEL without Coding – Standards-Based Process Support

Import models from WebSphere Business Modeler

Develop executable process – WS-BPEL-based business processes – WS-BPEL with or without IBM

extensions

Intuitive drag-and-drop tools– Visually define the sequence and flow

of business processes

A visual business process debugger– Step through and debug business

processes

Integrated fault and event handling– Provide an easy and integrated means of handling in-flow exception

handling and external events

Compensation support – Provide a logical “undo” capability

Two Styles of Service Choreography

Business Processes

– Traditional Business Processes

– Full support for WS-BPEL

– Import from WebSphere Business Modeler

Business State Machines

– Event-driven Business Processes

– Full support for State Machine programming model• States, Events, Transitions,

Actions, Guards, …• State Machine Authoring /

Debugging / Logging

– Event driven businessprocesses

– Creates WS-BPELunder the covers

Simple/Complex States– Entry/Exit

Transitions– Events

– Actions (invokes)

– Guards

– Timeout

Software



BPC Standard Client – BPC ExplorerGraphical View for Processes

Provide graphical view for process structure and instances

– Actions in the graphical view:• Zoom and scroll within the view• Expand and collapse event, fault

and compensation handlers• Show additional information about

elements when moved over• Navigate to activity details view

Usage scenarios

– Understand process structure

– Check status of process and its activities

Like process instance monitor in WebSphere MQ Workflow

Software



BPC Standard Client – BPC ObserverReporting for Business Processes

Allows observing state and evolution of business processese.g., overall duration, actual work time

Provides customizable reports and graphical charts of historical and accumulated data of business processes

Supports flexible drill-down capabilities to retrieve statistical data on processes and activities

Has been available as sample in 6.0.1 and is now a fully supported product feature

20

Software



BPC Standard Client – BPC ObserverReporting for Business Processes – Technical Background

BPC Observer has same look & feel as BPC Explorer– Built with JSF and BPC JSF Components

Collects BPC emitted events leveraging CEI

– Can observe multiple BPC containers

Configuration is part of overall BPC

– Also available in WID

Business RulesOverview

Business Rules allow to externalize business logic from applications (business processes)

Business Rules can be dynamically updated at runtime using the Business Rules Manager web application

• NLS enabled free text representation for rules

Business Rules provide the most-requested rules functionalities– Decision Tables

– Rule Sets (If/Then Rules)

– Rule Templates

– Action Rules

Rules Groups are provided for ease of use– Allow encapsulation of detailed implementation in a

component with a well defined interface

22

Software



Dynamicity with Business Rules

ToolsWebSphere Integration Developer

RuntimeWebSphere Process Server

Using Business Rules Manager, the Business Analyst changes rules at runtime

No need to restart the application

Users are authenticated using standard WAS authentication / security

Changes may be exported back to WID

Programmer defines rules from templates

This exposes the rule parameters to Business Rules Manager

Server Controlled Page Flow (aka Single Person Workflow) Automatically present users with the page for the next task in the process

Controlling the flow of UI interactions with a single individual

– Series of human tasks in a process to be performed by the same person

– Each page represents a human task

Dynamic Service SelectionOverview

Selection is based on a Selector Algorithm

– Framework for custom selector algorithms

The default Selection is date based

Date Based Selection

Target Components

Client makes a call to the Selector Component

Selector determines dynamically which implementation of a target destination to invoke

26

Software



Dynamicity using Dynamic Service Selection

At runtime System Administrator can modify/add/delete

– Modify or add the date/time

– Target component• From a list of installed

Components with the matching interface
