Dynamic Messaging with Microsoft BizTalk Enterprise Service Bus (ESB) Toolkit

Ryan CrawCourIndependent Consultant & Integration SpecialistSession Code: SOA 307

Session Objectives

Understand the ESB architectural pattern and its place within the overall Application PlatformUnderstand the architecture of the ESB ToolkitSee the capabilities and features of the ESB Toolkit, and how they can accelerate ESB deploymentsDiscuss the scenarios where it is appropriate to use instead of traditional BizTalk

So What’s The Difference?

BizTalk was positioned as a Hub and spoke

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

All decisions are made and locked in at Design Time or at Deployment!

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

We’ve allowed the easy to use tools to define how we leverage the BizTalk features!

Enter The ESB Guidance V1

Jointly developed by Patterns and Practices and the Connected SystemsWhat was its goal?

Demonstrate the ESB pattern using BizTalk Reduce the amount of “plumbing” you need to doReduce the total cost and effort needed for an ESB

The Core ESB Guidance Concepts

Itineraries

ResolversAdapter Providers

Itinerary Concept

Heart of the ESB GuidanceProvide runtime flexibility that BizTalk doesn’t have by defaultProvide a service composition mechanism

Creating An Itinerary

Ways to Assign ItinerariesClient sends message to Itinerary Generic On-Ramp, pipeline component selects an itinerary using configurable resolver

ServiceProxy

Client sends request to an Itinerary On-Ramp passing itinerary SOAP or WCF Header

AdvancedServiceClient

Client resolves itinerary via resolver service and then sends request to On-Ramp with itinerary header

AdaptiveServiceClient

Resolvers

For runtime flexibility ESB Services are not hard-coded to specific endpoints or mapsResolver mechanism can locate and retrieve this metadataItineraries define which ESB services execute and in which orderResolvers define how ESB services execute

Service CompositionComposing, Choreographing or “Chaining” services is a key capability for an ESB

Physical Service Physical Service Physical Service

Composed Service

Service Composition In V2

We have the “Itinerary Forwarder”

Allows straight-forward chaining of services using only BizTalk ports

Orchestrations can be used to create more complex business processes across services

BizTalk and the ESB Toolkit in actiondemo

ESB Administration PortalOverview

ASP.NET-based sample applicationThis is a sample of how ESB operational metrics and data can be surfacedProcess or group-specific portals could be created in SharePoint, leveraging ESBG assets such as BAM tracking and exception handling

http://localhost/esb.portal/

What Else Is New In V2?

Provides enhanced tooling, on top of an optimized coreProvides even more extensibility pointsIncludes a simplified install processesIncludes a new configuration tool

Configure core services and portalConfigure runtime stores

SummaryWhat it gives you…

Loosely-coupled messaging environmentRegistry-driven message routingItinerary-based processingLogically-centralized messaging fabric

Why you want it…Higher levels of reuseLower operational costsDynamic business changesCollection point for business, service, and exception metrics
