On Monday Microsoft announced the release of the next version of the ESB Toolkit (renamed from the ESB Guidance). The toolkit and it’s documentation is available for download, there is a ESB Toolkit MSDN site as well as a forum.
The ESB Toolkit 2.0 provides key building blocks required for implementing a service-oriented infrastructure (SOI) including:
- Endpoint run-time discovery and virtualization. The service consumer does not need to be aware of the service provider location and endpoint details; a new or modified service provider can be added to the ESB, without interruptions to the service consumer.
- Loosely coupled service composition. The service provider and service consumer do not need to be aware of service interaction style.
- Dynamic message transformation and translation. The mapping definition between distinct message structure and semantics is resolved at run time.
- Dynamic routing. Run-time content-based, itinerary-based, or context-based message routing.
- Centralized exception management. Exception management framework, services, and infrastructure elements that make it possible to create, repair, resubmit, and compensate fault messages that service consumers or BizTalk components submit.
- Quality of service. An asynchronous publish/subscribe engine resolves different levels of service availability and provides high availability, scalability, and message traceability for ESB implementations.
- Protocol transformation. Providing the ability for service provider and service consumer to interact via different protocols including WS-* standards for Web Services. For example, a service provider can send an HTTP Web Service request, which will result in sending a message via Message Queuing.
- Extensibility. Provides multiple extensibility points to extend functionality for endpoint discovery, message routing, and additional BizTalk Server adapters for run time and design time.
