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

BizTalk & ESB toolkit... BizTalk is all about providing solutions based on configuration Configuration happens at dev time or post- deployment ESB Toolkit is all about runtime resolution, it interacts with external stores (e.g., service registry) to get operational configuration in a JIT manner ESB Toolkit adds a set of runtime resolution capabilities that BizTalk developers would need to create from scratch

Enter Microsoft ESB Toolkit… From Patterns and Practices Provides architectural guidance, patterns and practices Delivers reusable BizTalk Server ESB and.NET components Enables construction of large and small-scale ESB solutions

Itinerary Processing Resolvers Adapter Providers The Core ESBT Concepts

Itinerary Processing Itinerary Concept Heart of the ESB toolkit Itineraries help provide the runtime flexibility that BizTalk doesn’t have by default Itineraries provide a service composition mechanism

Itinerary Processing Developing Itineraries with ESBT 2.0 Leverages VS 2008 and its capabilities for Domain Specific Languages We now have a Visual Itinerary Designer Avoid creating itineraries in plain old XML (no more Notepad) Validate itinerary model at design-time Export capabilities to the Itinerary repository (SQL) and file Migration tool to move between environments

Itinerary Processing Developing Itineraries with V2

Itinerary Processing Using Itineraries Design Time XML File Itinerary Database Run Time ItineraryItinerary OnRampOnRamp Itinerary Selector ESBProcessingESBProcessing Itinerary & Message MessageMessage

Itinerary Processing Three Ways to Assign Itineraries 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 Advanced Service Client Adaptive Service Client Service Proxy

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

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