The BizTalk ESB Toolkit 2.0, formerly known as the ESB Guidance 2.0 - was released on the June 9th to the web on the new ESB page in the BizTalk Developer Center on MSDN.
This toolkit is a collection of tools and libraries that extends BizTalk Server 2009 capabilities of supporting a loosely coupled and dynamic messaging architecture. It functions as middleware that provides tools for rapid mediation between services and their consumers. Enabling maximum flexibility at run time, the BizTalk ESB Toolkit 2.0 simplifies loosely coupled composition of service endpoints and management of service interactions.
Reason for Name Change
With the release of the BizTalk ESB Toolkit 2.0 and the associated renaming from “ESB Guidance,” the goal is to provide the toolkit as a BizTalk Server 2009 value-add with a better support model that results in abroader customer adoption. This will hopefully help customers develop mature ESB implementations that will be ready for enterprise-wide deployments.
The BizTalk ESB Toolkit 2.0 provides both architectural enhancements and new capabilities over the previous ESB Guidance. For more information, see SOA and Web Services section in the New Features in BizTalk 2009 Web page.
