What is BizTalk Server? Connecting applications within a single organization, commonly referred to as enterprise application integration (EAI). Connecting applications in different organizations, typically referred to as business-to-business (B2B) integration. Business Process Management (BPM) Server. It enables automation and integration of business processes.

BizTalk Server Architecture The BizTalk Server runtime is built on a publish/subscribe architecture, sometimes called "content-based publish/subscribe". Messages are published into the system, and then received by one or more active subscribers. Durable Messaging Adapters and Orchestrations Business Activity Monitoring

What is an ESB? Enterprise Service Bus… It is a Standards-Based Abstraction Layer Centrally exposes services (e.g. routing, transformation) Capabilities are pluggable and can be mixed-and-matched Enables client selection of services and processing instructions

Examining BizTalk Message Routing Architecture BizTalk Server Is Generally Statically Configured Requires static configuration up front, at design time or deployment Component changes require reconfiguration or redeployment Hub-and-Spoke

Common Requirements for a ESB Solution Messaging Service Invocation Dynamic Transformation Dynamic Routing (including Protocol Mediation and Endpoint Resolution) Loosely-Coupled & Event-Driven WS* Support Quality of Service (QoS) Management

Why ESB? Configurable, reusable architecture Addresses common concerns generically - Routing, Transformation, Exception Handling, Monitoring etc. Enforces Consistency and Unification Leverages modern Standards (WS-*), still supports Legacy Central point for Service Monitoring and Administration Increases agility (through added Abstraction, Loose coupling) Faster implementation times (through Configuration vs. Coding)

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

Key ESB Terms

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

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
