The document discusses the concept and definition of an Enterprise Service Bus (ESB) in relation to Service-Oriented Architecture (SOA), highlighting its functions such as message routing and transformation. It presents the motivations for implementing an ESB, its benefits for business processes, and addresses the challenges of choosing the right integration suite or developing custom solutions. Overall, it emphasizes the importance of understanding architectural needs and requirements to effectively leverage ESB and SOA structures.

15. 3 Definition of an ESB – a try

16. There is no standard definition for an ESB Commentators disagree over whether to define an enterprise service bus as an architectural style , a software product , or a group of software products . While use of an ESB certainly implies adherence to a particular architecture, the term "enterprise service bus" almost always denotes the software infrastructure that enables such an architecture, and in essence, the ESB is considered a platform to realize a service oriented architecture . An Enterprise Service Bus (ESB) brings flow-related concepts such as transformation and routing to a service oriented architecture. An ESB can also provide an abstraction for endpoints . This promotes flexibility in the transport layer and enables loose coupling and easy connection between services. Source: wikipedia engl.

17. Why a Service Bus: A few examples …

18. Example: Location Transparency

19. Example: Backwards Compatibility

20. Example: Service Enablement

27. Is an ESB enough? Could a suite be an option? A suite includes all established concepts I don‘t need everything a suite offers me YAGNI “You Ain’t Gonna Need It”, This comes out of extreme programming. The principle means that you should only develop what you really need. Programming should be concentrated on the application problems and not on infrastructure Somebody has already built it  just use it First Rule of developing your own framework: Don't do it! Suite provides innovation and stability Suite will be continuously improved It is expensive Not really, there are alternatives like open source suites
