Two Views of BizTalk?
BizTalk was positioned as a Hub-and-Spoke…
Now it’s an Enterprise Service Bus?

BizTalk... BizTalk+ESB Guidance...
BizTalk is all about providing solutions based on configurationConfiguration happens at dev time or post-deploymentESB Guidance is all about runtime resolution, it interacts with external stores (e.g., services registry) to get operational configuration in a JIT mannerESB Guidance adds a set of runtime resolution capabilities that BizTalk developers would need to create from scratch
![Page 10: Brian Loesgen Principal SOA Architect Microsoft Corporation SOA317](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649d0b5503460f949dde2f/html5/thumbnails/10.jpg)
Enter Microsoft ESB Guidance…
From Patterns and PracticesProvides architectural guidance, patterns and practicesDelivers reusable BizTalk Server ESB and .NET components Enables construction of large and small-scale ESB solutions

ESB Guidance 2.0 Changes
Built on BizTalk Server 2009Provides greatly enhanced tooling, on top of an optimized coreProvides even more extensibility pointsProvide even more prescriptive guidance about enterprise integration patternsStreamlined installation experience (Powershell, configuration tool, etc)

Itinerary Concept
Heart of the ESB guidanceItineraries help provide the runtime flexibility that BizTalk doesn’t have by defaultItineraries provide a service composition mechanism
ItineraryProcessing
![Page 17: Brian Loesgen Principal SOA Architect Microsoft Corporation SOA317](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649d0b5503460f949dde2f/html5/thumbnails/17.jpg)
Developing Itineraries with V2
Leverages VS 2008 and its capabilities for Domain Specific LanguagesWe now have a Visual Itinerary Designer
Avoid creating itineraries in plain old XML (no more Notepad)Validate itinerary model at design-timeExport capabilities to the Itinerary repository (SQL) and fileMigration tool to move between environments
ItineraryProcessing

Three Ways to Assign Itineraries ItineraryProcessing
Client resolves itinerary via resolver service and then sends request to On-Ramp with itinerary header
Client sends request to an Itinerary On-Ramp passing itinerary SOAP or WCF Header
Client sends message to Itinerary Generic On-Ramp, pipeline component selects an itinerary using configurable resolver

Resolvers
For runtime flexibility ESB Services are not hard-coded to specific endpoints or maps
This metadata is determined at runtimeResolver mechanism can locate and retrieve this metadataItineraries define which ESB services execute and in which orderResolvers define how ESB services execute

Adapter Providers
The Itinerary and Resolver mechanisms are .NET components. The endpoint information produced by the resolvers is stored in .NET based Dictionary objectsWe leverage BizTalk dynamic ports to handle the actual routing of messages. However, BizTalk isn’t built to work with Dictionary objectsAdapter providers act as a bridge between the .NET based ESB components and the BizTalk based ESB components
AdapterProviders

Service Composition with
We have two optionsMessaging-based: Lightweight composition using only Itineraries and BizTalk ports (using ItineraryForward pipeline component)Orchestration-based: Orchestrations available for more complex business processes
