Session Objectives

Getting Business Value from SOA

Rich UX and visualisation

Microsoft Office Platform for consuming SOA/BPM

BizTalk Server 2009 – expose capabilities

• Introduction to this session

• Consume SOA in Silverlight

• Consume SOA in MOSS

• Platform for SOA – BizTalk Server 2009

Making SOA Real...

Service orientation is about decomposing the IT assets into consumable services

Making this work for a business is about understanding what data the service provides or needs

External data also needs to be surfaced

In the real world of SOA we need to use and aggregate the data and therefore the services

To make this real we must develop what are best referred to as composite applications

Silverlight delivers

rich interactive application

Sockets ( duplex )

Uses

We won‟t focus on implicit access

2 main classes for explicit access

WebClient offers simple GET/POST

HttpWebRequest offers more control

Browser API‟s limit HTTP verbs to GET/POST

Only basicHttpBinding is “in the box”SOAP 1.1, XML, HTTP(S)

not WS-Security, WS-Trust etc.

Derived PollingDuplexHttpBinding for duplex

Uses WS-Make Connection for polling over HTTP

Familiar Programming modelClient side object model

Configuration file - loaded from the XAP

“Add Service Reference” tooling in Visual Studio

ADO.NET Data ServicesRESTful services from .NET Framework V3.5 Sp1

Tunnels PUT/DELETE via POST to avoid the browser API HTTP limitation

What is a composite application?

“A collection of software assets that have been

assembled to provide a business capability”

Or

“Composed of a number of discrete and

independent pieces, aggregating functionality

through a software interface”

Fusion

Databases

Smart Client

Case Study

• This case study looks at the business process to update

customer details

Customer details are “mastered” in an existing LOB

ERP/financial system

Any employee can start the process to update a

customer‟s details, but the changes are checked,

moderated and approved in the process

The change to the master record is made without directly

accessing the LOB system

MOSS 2007 is used as a „consumer‟

Case Study

Summary

Composite applications deliver solutions that

leverage SOA

Composite applications equate to LOB applications

Composite applications allow business to maximise

data and information

With MOSS 2007, BizTalk 2009 and Visual Studio we

can deliver composite applications
