Overview

So What’s The Difference? Classic BizTalk Rethinking The Solution As A Set Of Capabilities When to use it Disadvantages Benefits Demo: Using ESB Itineraries Changes in BizTalk artifacts & ESB Process Change in a Map & XSD Demo: How to deploy changes Summary

So What’s The Difference?

BizTalk was positioned as a Hub and spoke

Now we’re saying it can be an Enterprise Service Bus?

Classic BizTalk

Static Receive Port

Hard-Coded Map Name

StaticSchema

Static Send Port

Statically bound orchestration

Single Service

Static Send Port

Statically bound orchestration

Single Service

Single Schema All decisions are made and locked in at

Design Time or at Deployment.

Any change is a re-development or a system re-configuration.

Rethinking The Solution As A Set Of Capabilities

Dynamic Resolution

Resolved Itinerary

Generic Off Ramp

Generic On Ramp

MultipleSchemas (xN)

Multiple Services (xN)

Transform ServiceRouting Process

Orchestration

Enables policy- or configuration-based routing at runtime

Avoids requirement to hard-code components and services

Page 6: To ESB Toolkit or not to ESB Toolkit ESB Toolkit patterns and practices Tomasso Groenendijk

When to use it

In the project is a need for Reusable Components, SOA & Agile Larger projects

The business processes in BizTalk can be divided in Reusable Components.

It’s required to have NO Downtime when deploying a change

The complexity of the business processes that is going to be automated in BizTalk is relatively simple.

As few as possible Receive Ports or Send Ports in BizTalk.

Low Latency scenarios.

You don't use Parties in the BizTalk solution (EDI)

Disadvantages

ESB Toolkit is Complex. Little documentation.

Installation is difficult. Framework (BizTalk 2009 / BizTalk 2010) Management Portal.

It’s not fully functional out of the box. Instead it provides a base set of ESB components

that must be extended. Management Portal is sample.

Performance Off Ramps are Dynamic Ports.

Benefits

Reusing of services Pipeline components & Orchestrations

Deployment of changes / new versions Orchestrations are not bound to a Map or a .XSD

Out of the box BAM

Centralized Error handling Management Portal

Performance Cache Low latency

Using Pipeline components instead of Orchestrations

Demo: Using ESB Itineraries

In this demonstration, you will see:

Using itineraries Itinerary Services Resolvers

Using Business Rules in a Resolver

Using Custom Messaging Services

Using Custom Orchestration Services

Rules

UBL SalesOrder

BSON document

WareHouse

Dynamics AX document

Warehousedocument

WareHouse DespatchAdvice Generic

Generic On Ramp

SalesOrder Itinerary

DynamicsAX Service

TrackingService

RoutingService

Changes in BizTalk artifacts & ESB Process

In the event of a change, there’s much less disruption with this model.

Modify Orchestrations Modify Maps Modify XSD schemas

The ESB layer can modify the configuration without changing the individual applications themselves.

Add / Remove Itinerary services Modify Resolvers Modify Business Rules

Page 12: To ESB Toolkit or not to ESB Toolkit ESB Toolkit patterns and practices Tomasso Groenendijk

Change in a Map

Deployment steps:

Disable specific Receive Locations

Only remove the maps from BizTalk BizTalkMgmtDb when deploying a change

Don't remove the Assembly from the GAC so other maps can still be executed

Orchestrations are not bound to a specific map because transformations are performed by MapHelper class

Don't have to be removed when deploying a change

Page 13: To ESB Toolkit or not to ESB Toolkit ESB Toolkit patterns and practices Tomasso Groenendijk

Change in a XSD schema

Deployment steps:

Disable specific Receive Locations

Only remove the maps from BizTalk BizTalkMgmtDb Don't remove the Assembly from the GAC so other

Maps can still be executed

Only remove the XSD schemas from BizTalk BizTalkMgmtDb Don't remove the Assembly from the GAC so other

XSD schemas can still be executed

Orchestration are not bound to a specific XSD schema because the Message Type is XmlDocument

Don't have to be removed when deploying a change

Maps are bound to a specific XSD schema

Demo: Deploying changes with NO Downtime for other Processes

In this demonstration, you will see:

Deploy a change in Business Process

Deploy a change in a Map

Deploy a change in a XSD schema

Summary

Provides the right benefits to cope with complex and rapidly changing integration challenges

Higher levels of SOA, Service re-use

Faster adaptation to business changes

Visibility business and exception metrics

Highly extensible to introduce new functionality or encapsulate patterns

Centralized exception management
