Emerging SOA + BPM Standards, Software and Platforms
2 likes522 views
The document discusses emerging standards around service-oriented architecture (SOA) and business process management (BPM). It covers topics such as the emergence of SOA and how services are described. SOA technology is discussed, with a focus on enterprise service buses. The emergence of BPM is also introduced. The document presents an agenda that will cover additional topics like classifying process types, process definition languages, BPM technology, service-oriented business applications, and development paradigms.

- 4. Emergence of SOA, 1 Is SOA something new? UNIX kernel of 1970's with clear application programming interface (API)? Desktop applications of 1980's in which presentation logic was separated from client business logic by an API? Enterprise Application Integration (EAI) of 1990s? Definitions Service-Oriented Architecture (SOA) is an architectural style that supports service orientation (Open Group) Service orientation is a way of thinking in terms of services and service- based development and the outcomes of services (Open Group) Service Is a logical representation of a repeatable business activity that has a specified outcome (Open Group) Is a “black box” to consumers of the service (Open Group) Produced by: Tarmo Ploom Date: 06/09/2009 Slide 4
- 5. Emergence of SOA, 2 SOA is architectural style SOA is based on the design of services – which mirror real-world business activities – comprising the enterprise (or inter-enterprise) business processes (Open Group). SOA is a way to describe logical architecture Every technology can be used as basis for SOA There have always been interfaces but designing of services, which reflect real-world business activities is relatively new SOA places unique requirements on the infrastructure – it is recommended that implementations use open standards to realize interoperability and location transparency (Open Group).

- 7. Service description, convergence of standards Development of service description languages = development of abstraction 1980s proprietary service definition languages (C, C++, PL1, COBOL) proprietary socket based transport protocols abstraction on Platform Specific Model (OMG) level 1990s IDL, standardized interface definition language (OMG) standardized transport protocol IIOP (OMG) abstraction on Platform Independent Model (OMG) level 2000s WS-family, standardized service definition language standardized message exchange patterns => transport and definition decoupled abstraction on slightly higher level than Platform Independent Model (OMG) Produced by: Tarmo Ploom Date: 06/09/2009 Slide 7
- 8. Service description, message exchange patterns Classification of services in OMG IDL synchronous (request-response, in-out) asynchronous (fire-and-forget or notification or out-only) Additions in W3C WSDL 1.0 + solicit-response operation + one-way operation (in-only) Additions in W3C WSDL 2.0 + out-in pattern + robust in-only pattern + robust out-only pattern + in-optional-out pattern + out-optional-in pattern Produced by: Tarmo Ploom Date: 06/09/2009 Slide 8
- 9. Service description, WS-family Business process related WS-BPEL (BPEL) – executable process definition WS-Coordination – context management for BPEL WS-BusinessActivity – long term business activities WS-AtomicTransaction – classical ACID transactions WS Extensions WS-Adressing - standardize representation of service endpoint locations WS-ReliableMessaging – guaranteed delivery of SOAP messages WS-Policy – express metadata about security, processing, content WS-MetadataExchange – standardizes service description metadata exchange WS-Security – end-to-end security, authentication, authorization Produced by: Tarmo Ploom Date: 06/09/2009 Slide 9
- 10. Service description, semantic interoperability We have achieved technical interoperability But did we achieve semantic interoperability? Do clients understand service providers? SAP integration projects 10% effort technology 90% semantic understanding How to achieve semantic interoperability?

- 12. SOA technology, focus on ESB Definition ESB is a new architecture that exploits Web services, messaging middleware, intelligent routing, and transformation (Roy Schulte) ESB is convergence of current middleware technologies which involves WS-family standards Message exchange patterns Message transformation/routing Orchestration .... Future Forrester suggests convergence between ESB and system-to system integration BPM engines (Forrester Research) Produced by: Tarmo Ploom Date: 06/09/2009 Slide 12
- 13. SOA technology, ESB and beyond Limits of ESB Does ESB support high transaction volume platform (> 1 Million Tx/hour)? Does ESB support bulk data transfer (> 100 MB)? Latency in international SOA? Scalability issues? Complexity ad manageability of solutions? Our cognitive limits to handle complexities in ESB-s? Produced by: Tarmo Ploom Date: 06/09/2009 Slide 13
- 14. SOA technology, future is open Service Integration Maturity Model (Ali Arsanjani ) Level one – ad hoc integration Level two – Enterprise Application Integration (EAI) with proprietary connectors Level three – componentization of existing landscapes, integration of components through their interfaces Level four – organization starts to define and expose SOA services internally or for business partners Level five – organization extends its influence to value chain Level six – organization creates virtualized infrastructure to run applications. Decoupling of applications, its services, components and processes Level seven – organization has dynamically reconfigurable software architecture. It can compose services at run-time using externalized policy description, management and monitoring Produced by: Tarmo Ploom Date: 06/09/2009 Slide 14

- 29. SOBA - Service Oriented Business Applications, definitions Gartner calls them "SOBA" Service Oriented Business Applications (SOBAs) will enable enterprises to dynamically compose and decompose applications according to business needs Forrester calls them "Dynamic Applications" Dynamic applications — software that adds more visibility and collaboration to today's business processes, while adapting more quickly and cost-effectively to their changes — represent IT's worthiest hope for enabling real business agility. Aberdeen Group calls them "Composite Applications" Composite apps, logic and data collected from multiple IT sources, harnessed with web services standards, are rapidly becoming the development standard of choice in all IT organizations.
