7 Statements from OpenWorld 2008: Good progress of BEA integration into Oracle SOA stack best-in-class SOA infrastructure (Oracle WebLogic Server, Oracle WebLogic Application Grid, Oracle Business Process Management, Oracle WebCenter Suite) enhanced SOA Suite (new elements; all-in-one SOA starter kit) Extension of pre-built SOA-based integrations as part of AIA initiative Continuous SOA Investments: In the area of Composite WebServices For E-Business Suite and the other Business Applications Adherence of SOA-based design- und development principles for the next-generation Fusion applications Oracle SOA toolbox SIG SOA 7

8 What about the Oracle SOA Strategy? Modularity is good in SOA technology, but is not so good in SOA messaging Oracle should have inherited some of BEA s focus on SOA along with BEA s SOA technology Oracle has plenty of SOA-related work underway, and can claim parity and even superiority to IBM on many SOA fronts What Oracle has yet to demonstrate or articulate, however, is a consistent and over-arching SOA message or approach to this market.

9 2 SOA Blueprint Oracle SOA toolbox SIG SOA 9

10 Reference architectures Reference architecture = Desired ideal of achievable IT landscape (beacon on the horizon) Way to implement a reference architecture is long: (external) influences cause nessecary variations Chief architects: stay on path, adjustment of implementation Constant checking and adjustment nessecary to prevent SOA spaghetti mess Not only for the duration of one project, but for the whole SOA transformation Oracle SOA toolbox SIG SOA 10

11 Vision: Adaptive Enterprise Computing Oracle SOA toolbox SIG SOA 11

12 SOA Blueprint Oracle SOA toolbox SIG SOA 12

13 Another AIA : Accidental Integration Architecture Oracle SOA toolbox SIG SOA 13

14 Bringing system to the toolbox The best filled toolbox doesn t guarantee optimal solutions Mission of the architect is to bring system to the toolbox Each tool must be perfectly known for its function and area of application: Which tool is used best for which area of application? Which tools optimal play together in sense of SOA Blueprint Will the reference architecture be broken? Which combinations hold difficulties or redundancies? Outcome of complex projects depends highly on the experience and qualities of the responsible architect Oracle SOA toolbox SIG SOA 14

26 4 Tools in specific contexts Oracle SOA toolbox SIG SOA 26

27 Things BPM Local Workflow/EAI projects vs. Enterprise Level BPM/SOA 27 / 19. Sept. 2008/

28 Nature of many BPM projects: Workflow, almost no business services Directly implemented as workflow tasks, not as SOA Business Services Directly implemented database adapter, not as SOA Business Service Oracle SOA toolbox SIG SOA 28

29 Nature of many projects: Organizational context local; rather workflow than BPM Fulfillment SAP-CRM Billing Silo specific functionality Redundant functionality Internal processes (task driven, no interaction with other silos) Oracle SOA toolbox SIG SOA 29

30 .. as compared to cross silo end to end processes: Enterprise level (or at least domain level) BPM/SOA SILO 1 SILO 2 SILO 3 Shared Services Oracle SOA toolbox SIG SOA 30

31 Local Workflow/EAI projects vs. Enterprise Level BPM/SOA Enterprise BPM -Addresses otimizations the way the organization interacts with customer and homogenizes inner procedures - Uncontrolled environment: Information is spread over departments, you need stroing governance to know how to retrieve information or change something Local project, remaining in siloes -Addresses otimizations of human interactions with systems in one department - Controlled environment: You go to the developer next door or look in well known known log files when investigating something These differefferent contexts have impacts on the feasible tools and their usage! Oracle SOA toolbox SIG SOA 31

32 The impact of context on tools: Local Workflow Projects using SOA/BPM Technology Pure BPMN is sufficient -> BPM Suite (Ex-Fuego) rather than BPA Suite No UDDI is necessary for data stewardship No UDDI and ESB necessary for service virtualization and reuse Business Rule Engine not justified, some developers might play with it. Oracle SOA toolbox SIG SOA 32

33 The impact of context on tools: Enterprise Level BPM Pure BPMN is not sufficient, BPMN is embedded process hirarchies and in other larger scopedea models -> BPA Suite UDDI and ESB necessary for service virtualization and reuse -> UDDI is necessary for data stewardship, ESB for complex transformations -> Oracle misses semantical type definition and mapping tool Business Rule Engine justified for central place to define and investigate important business rules Oracle SOA toolbox SIG SOA 33

34 ESB in Context Where to put my Routing and Integration Logic?? ESB Puzzles and Answers for SOA Suite 11 with and without new Oracle ESB (Ex- BEA ALSB) 34 / 19. Sept. 2008/

35 A loosely coupled design for a SOA Business Service based on AIA Enterprise Business Flow (EBF) A Based on process model in BPA Suite and executable in BPEL Service Registry Design Time enables analysts and developers to find services and its meta data (XML schema etc.) Runtime resolves endpoint URLs Var 1 Var 2 What is location URL of A? ESB based implementation for Business Service (EBS) A Application Business Connector Services (ABCS): ESB based adapter service for Peoplesoft Peoplesoft ABCS for SIEBEL SIEBEL Stateful orchestration Complex enrichment Routing (if it depends on variable, not message content) Keep no state (no variables) Call services along a chain Simple enrichment do routing (if it depends on message content) Handles Mediation (Syntactic transformation from / to canonical model) Calls endpoint Oracle SOA toolbox SIG SOA 35

36 An AIA based business service in 11 Classic fulfill Order BPEL based Business Process WSDL Service Registry (UDDI) Stateful Activity Service EBF fo Orchestrates; decides on implementation Stateless integration Process EBS fo Adapter Service ABCS X Mediator System X Var 1 Var 2 Mediator Adapter Service ABCS Y System Y Mediator if Var 1 > else Stateful Workflow fullfillorder Service D BPEL BPEL SCA Composite fulfill Order Oracle SOA toolbox SIG SOA 36

37 Well now this is the advice we got at Oracle HQ: BPEL fulfill Order WSDL Oracle ESB (Ex-BEA-ALSB) Service Registry (UDDI) Now, where did my nice Fabric with all the beauty of SCA go? After all, this was at the core of Thomas Kurian s story of 11 that watered our mouths since two years, wasn t it? After many discussions at OOW, we came up with this... Oracle SOA toolbox SIG SOA 37

38 A business service implementation in 11 plus new ESB fulfill Order Service Registry BPEL WSDL Oracle ESB: (UDDI) Entry Point and data- and implementation virtualization for fulfill Order Stateful Activity Service EBF A Orchestrates; decides on implementation Stateless integration Process EBS A Adapter Service ABCS X Adapter Service ABCS Y System X System Y Var 1 Var 2 Oracle ESB if Var 1 > else Stateful Workflow Service D BPEL BPEL Oracle SOA toolbox SIG SOA SCA Composite A 38

39 A business service implementation in 11 plus new ESB fulfill Order Service Registry BPEL WSDL (UDDI) Data: Translates to canonical data model Oracle ESB: Entry Point and data- and implementation virtualization for fulfill Order Stateful Activity Service EBF A Orchestrates; decides on implementation Var 1 Var 2 Stateless integration Process EBS A Data: Translates to local dialects Adapter Service ABCS X Adapter Service ABCS Y Oracle ESB System X System Y if Var 1 > else Stateful Workflow Service D BPEL BPEL Data: Deals purely with canonical format Oracle SOA toolbox SIG SOA SCA Composite A 39

40 A business service implementation in 11 plus new ESB Assessment Pro: More mature, richer ESB features: Variables, XQuery-Editor Better separation of concerns: Separate integration logic from business composites Contra (as for first realease of 11, might resolved when integrated): Adds confusion, unclearer desings Different IDEs and runtime Oracle ESB not integrated in JDeveloper Oracle SOA toolbox SIG SOA 40

41 Tradeoff: Routing logic in the business service... fulfill Order BPEL based Business Process WSDL Service Registry (UDDI) Stateful Activity Service EBF fo Orchestrates; decides on implementation Integration Process fulfillorderasintegrationprocess Adapter Service ABCS X System X Var 1 Var 2 Adapter Service ABCS Y System Y if Var 1 > else Stateful Workflow fulfill Order as Workflow BPEL Service D SCA Composite fulfill Order Oracle SOA toolbox SIG SOA 41

42 Tradeoff: Routing logic in the business service - the beauty of loose coupling: Change the implementation does not change the process (stable as longs as WSDL stays stable) WSDL WSDL fulfill Order BPEL based Business Process Service Registry (UDDI) Stateful Activity Service EBF fo decides on implementation Implementation as Rule Var 1 Var 2 if Var 1 > else Rule Service BPEL SCA Composite fulfill Order Service fullfillorder from Partner Company Oracle SOA toolbox SIG SOA 42

43 Tradeoff: Routing logic in the business service Let s take a look how we could move the decision on implementation from within the service -> up to the business process (next slide) fulfill Order BPEL based Business Process WSDL Service Registry (UDDI) Stateful Activity Service EBF fo Orchestrates; decides on implementation Integration Process fulfillorderasintegrationprocess Adapter Service ABCS X System X Var 1 Var 2 Adapter Service ABCS Y System Y if Var 1 > else Stateful Workflow fulfill Order as Workflow BPEL Service D SCA Composite fulfill Order Oracle SOA toolbox SIG SOA 43

44 Decision on implementation at Process Level (preferred when decision rule is business relevant) if Var 1 > fulfill Order as Workflow BPEL based Business Process else fulfill Order as Internal Integration Process Integration Process fulfillorderasintegrationprocess Adapter Service ABCS X System X Adapter Service ABCS Y System Y Stateful Workflow fulfill Order as Workflow Service D Pro: Business relevant decision in Process Model Con: Tighter coupling between process step and implementation (a bit Anti-SOA ) Oracle SOA toolbox SIG SOA 44

45 Orchestration in three years: Will BPEL survive? Oracle SOA toolbox SIG SOA 45

46 Usages of BPEL today: Business Process, Workflow, Integration Process fulfill Order Model: BPMN (e.g. in BPA Suite); Executable: BPEL Stateful Activity Service EBF fo Orchestrates; decides on implementation Stateless integration Process EBS fo Adapter Service ABCS X Adapter Service ABCS Y Var 1 if Var 1 > Var 2 else Stateless Integration pipes: Not BPEL; BPEL if statefull Stateful Workflow fullfillorder Service D Complex Integration Logic: BPEL Workflow: BPEL Oracle SOA toolbox SIG SOA 46

47 The future of BPEL fulfill Order Model: BPMN 2.0; Executable: BPMN 2.0 Stateless Integration pipes: Oracle ESB: non BPEL-based EAI flow Entry Point for fulfill Order Stateful Activity Service EBF A Orchestrates; decides on implementation Stateless integration Process EBS fo Adapter Service ABCS X Adapter Service ABCS Y Var 1 Var 2 Integration pipes: non BPELbased EAI flow Oracle ESB if Var 1 > else Stateful Workflow Service D Complex Integration Logic: Workflow: BPMN 2.0 BPEL - or non BPEL based EAI flow in Oracle ESB Oracle SOA toolbox SIG SOA SCA 47
