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

Enter Microsoft ESB Guidance… 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

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

Itinerary Processing Resolvers Adapter Providers The Core ESBG Concepts

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

Developing Itineraries with V2 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 Itinerary Processing

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

Three Ways to Assign Itineraries Itinerary Processing 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

Using ESB Itineraries and Resolvers

Service Composition Composing, Choreographing or “Chaining” services is a key capability for an ESB Physical Service Composed Service

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

ESB Administration Portal Overview Sample application, used for an IT Pro type view into the ESB Located at ASP.NET-based This is a sample of how ESB operational metrics and data can be surfaced Process or group-specific portals could be created in SharePoint, leveraging ESBG assets such as BAM tracking and exception handling

ESB Administration Portal Features The Portal provides Graphical metrics Repair and resubmit functionality Alerting based on exception events Auditing trails for repair and resubmit Unified view of the.NET Exception data + BizTalk message + BizTalk context properties Historical views of exception data Remote web-based access Filtering of exceptions based on application
