Patterns: Extended Enterprise SOA and Web Services

6 Patterns: Extended Enterprise SOA and Web Services

1.3 How to read this redbook

As much as the redbook team would love you to read every page of this book

cover-to-cover, we anticipate this may not be the case for every reader! To help

you locate the information you need, and to provide guidance on which chapters

are of most interest to you, this section provides a short description of each

chapter.

Part 1. Patterns for e-business and Extended Enterprise

This part introduces the Patterns for e-business and the issues with connecting

to an external enterprise. It then describes the products and patterns for

implementing Extended Enterprise solutions.

򐂰 Chapter 1. Welcome to this redbook

򐂰 Chapter 2. Introduction to the Patterns for e-business

The Patterns for e-business are a group of proven, reusable assets that can

be used to increase the speed of developing and deploying e-business

applications. This book uses the Patterns for e-business to indicate how to

develop and deploy SOA solutions. This chapter provides an introduction to

what the Patterns for e-business are at a general level.

򐂰 Chapter 3. Beyond the enterprise

Discusses the issues of connecting to business logic running in external

enterprises, from a traditional and Web services viewpoint. This is targeted at

readers wishing to gain a fuller understanding of the issues involved in

communicating with an Extended Enterprise.

򐂰 Chapter 4. Extended Enterprise pattern

Describes the Extended Enterprise business pattern and Application patterns

from the Patterns for e-business. These high level patterns help describe the

common interactions between multiple enterprises, and the tiers required to

implement these interactions.

򐂰 Chapter 5. Product descriptions

Describes the IBM products discussed and implemented within this redbook

to implement Extended Enterprise scenarios.

򐂰 Chapter 6. Extended Enterprise runtime patterns

Explains the Extended Enterprise runtime patterns for the Patterns for

e-business. Each Runtime pattern describes the logical architecture that is

required to implement an Application pattern. Both generic and SOA Runtime

pattern profiles are discussed.

򐂰 Chapter 7. Product mappings

Chapter 1. Welcome to this redbook 7

Product mappings are typical and proven implementations of a Runtime

pattern, using IBM products. This chapter highlights product mappings for

each Extended Enterprise runtime pattern. Most of these product mappings

are implemented in Part 3 of this redbook.

Part 2. Business scenario and guidelines

This redbook provides six Extended Enterprise scenario implementations, based

on the product mappings from Chapter 7. Each of these scenario

implementations uses a common business scenario case study, and a collection

of technologies. These are introduced in this section.

򐂰 Chapter 8. Business scenario used in this book

Describes the business scenario used throughout Part 3 of this redbook. The

business scenario is based on a sample application provided by the Web

Services Interoperability Organization (WS-I).

򐂰 Chapter 9. Technology options

Introduces the technologies required to implement Extended Enterprise

interactions using Web services.

Part 3. Scenario implementation

Six Extended Enterprise scenarios are implemented in this section, based on the

Runtime patterns identified in Chapter 6 and the product mappings described in

Chapter 7.

Each scenario chapter is divided into three distinct parts:

򐂰 Design guidelines

Primarily intended for architects. This section describes the design

alternatives that you should consider when designing a particular scenario.

򐂰 Development guidelines

Primarily intended for application developers. This section describes the

application development changes that are required when implementing a

particular scenario.

򐂰 Runtime guidelines

Primarily intended for system administrators. This section describes how to

deploy a particular scenario, and the runtime alternatives that are available.

This redbook contains the following scenario chapters:

򐂰 Chapter 10. Exposed Direct Connection runtime pattern: generic profile

Describes how to design and build a basic Extended Enterprise solution using

point-to-point connections between Web services, including the use of
