- 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.

- 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

Editor's Notes
- #6: Nach Thomas Erl: a vision that defines a target state a formal paradigm that defines a method for achieving the target state technology innovation that improves the benefit potential of the target state technology architecture capable of realizing the target state formal practices and patterns that support the creation and evolution of the target state
- #10: Das ist das problem
- #11: Nicht nur tolles tool
- #12: Business ist im vordergrund
- #13: Mehrwert kann im department passieren Mehrwert wird wahrscheinlich eher übergreifend end-to-end aufgesetzt -> it muss das enablen
- #14: Wie reden diese Domainen miteinander Modern ESB - Embrace heterogenicy Story for modern vs traditional
- #20: Event pattern heraussuchen
- #27: Botschaft: egal was du mal brauchst, das ist dann halt in der SUite Botschaft: du brauchst es nicht nutzen Botschaft: du keine Suite, dann pass auf, dass du upgradefähig bleibst.
- #28: Esb is part of a suite Modern environments need more then the core ESB functionality You should not concentrate on plattform integration
- #33: Standardfolie Idealerweise 5-7 Hauptpunkte oder 3 Hauptpunkte mit Unterpunkten GGf. Hauptpunkte untereinander horizontal abgrenzen (Menu Format / Zeilenabstand / Abstand vor einem Absatz = 1 Zeile bei den Zeilen mit Hauptpunkten!)
- #44: OSB: 16 MULE: 7 SM: 3
- #49: SCA terminology: Composite : deployment unit Service : entry-point into composite Component : provides logic Reference : refers to external services Wire : connects services, components and references – no special semantic. Bindings: Access interactions with outside a composite Vereinfacht die Entwicklung in Service Orientierten Architekturen Entwicklung konzentriert sich auf Implementierung der Geschäftslogik, SCA Umgebung regelt bzw. vereinfacht die technische Integration Vereinheitlichung / Standardisierung Technologie-abstrahierend, Integration, Wiederverwendung, Loose Kopplung Modulare Komposition von Komponenten, die in verschiedenen Implementierungssprachen umgesetzt sein können Trennung von Geschäftslogik, Middlewareabhängigkeiten und nichtfunktionalen Aspekten Wiederverwendung von Implementierungen in unterschiedlichen Konfigurationen
- #51: Can follow the message through all of components. With Search! Execution Context Identifier (ECID) is used by several other Oracle products, such as Oracle Portal
- #53: OPS4J = Oracle Platform Security For Java (JPS implementation) used for authentication and authorization. Upon entering Service Infra, a Java Subject is attached to the message and is used to propagate identity and other properties.
