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
Single Schema
Static Receive Port
Hard-Coded Map Name
StaticSchema
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
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
Demo: Using ESB Itineraries
PolicyPolicy
Rules
UBL SalesOrder
BSON document
WareHouse
Dynamics AX document
Warehousedocument
UBLReceiptAdvice
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
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
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
PolicyPolicy
Rules
UBL SalesOrder
BSON document
WareHouse
Dynamics AX document
Warehousedocument
UBLReceiptAdvice
WareHouse DespatchAdvice Generic
Generic On Ramp
SalesOrder Itinerary
DynamicsAX Service
TrackingService
RoutingService
Demo: Deploying changes with NO Downtime for other Processes
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
