To ESB Toolkit or not to ESB Toolkit ESB Toolkit patterns and practices Tomasso Groenendijk

So What’s The Difference?

BizTalk... BizTalk+ESB Toolkit...  ESB Toolkit is all about runtime resolution  It interacts with external services 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  BizTalk is all about providing solutions based on configuration  Configuration happens at dev time or post-deployment

Classic BizTalk Static Receive Port Hard-Coded Map Name Static Schema Static Send Port Statically bound orchestration Single Service Single Schema Static Receive Port Hard-Coded Map Name Static Schema Static Send Port Statically bound orchestration Single Service Single Schema  All decisions are made and locked in at Design Time or at Deployment.  Any change is a re-development or a system re-configuration.

Summary Provides the right benefits to cope with complex and rapidly changing integration challenges  Higher levels of SOA, Service re-use  Faster adaptation to business changes  Visibility business and exception metrics  Highly extensible to introduce new functionality or encapsulate patterns  Centralized exception management
