Oracle SOA toolbox SIG SOA 6 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 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.

Oracle SOA toolbox SIG SOA 8 2 SOA Blueprint

Oracle SOA toolbox SIG SOA 9 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 11 SOA Blueprint

Oracle SOA toolbox SIG SOA 12 Another „AIA“: Accidental Integration Architecture

Oracle SOA toolbox SIG SOA 13 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 25 4 Tools in specific contexts

Oracle SOA toolbox SIG SOA 26 Things BPM

Local Workflow/EAI projects vs. Enterprise Level BPM/SOA

27 / 19. Sept. 2008/ 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 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 .. 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 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 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

Business Rule Engine not justified, some developers might play No UDDI and ESB necessary for with it. service virtualization and reuse

Oracle SOA toolbox SIG SOA 32 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 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/ A loosely coupled design for a SOA Business Service based on AIA

Design Time enables analysts and developers to Enterprise Business find services and its meta data (XML Flow (EBF) “A” schema etc.) Based on process Service Registry Runtime model in BPA Suite resolves endpoint URLs and executable in BPEL

Application Business Var 1 What is location URL of „A“? Connector Services (ABCS): Var 2 ESB based adapter ESB based implementation service for „Peoplesoft“ Peoplesoft for Business Service (EBS) A“

ABCS for „SIEBEL“ SIEBEL

Stateful orchestration Keep no state (no Complex enrichment variables) Routing (if it depends Call services along a chain on variable, not Simple enrichment Handles Mediation message content) do routing (if it depends on (Syntactic transformation message content) from / to canonical model) Calls endpoint

BPEL BPEL

SCA Composite “fulfill Order”

Oracle SOA toolbox SIG SOA 36 Well – now this is the advice we got at Oracle HQ: fulfill Order Service Registry BPEL WSDL (UDDI) Oracle ESB (Ex-BEA-ALSB)

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 A business service implementation in “11 plus new ESB” fulfill Order Service Registry BPEL WSDL (UDDI) Oracle ESB: Entry Point and data- and implementation virtualization for “fulfill Order”

Adapter Stateless integration Service „ ABCS X“ Stateful Process „ EBS A” Activity Service „EBF A“ System X Orchestrates; decides on implementation Adapter Service „ ABCS Y“ System Y Var 1 Var 2 Oracle ESB

Oracle SOA toolbox SIG SOA SCA Composite “A” 38 A business service implementation in “11 plus new ESB” fulfill Order Service Registry BPEL WSDL (UDDI)

if Var 1 > 100.000 else Stateful Workflow

Service D

BPEL BPEL Data: Deals purely with canonical format Oracle SOA toolbox SIG SOA SCA Composite “A” 39 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 Tradeoff: Routing logic in the business service ...

BPEL based Business Process fulfill Order Service Registry WSDL (UDDI)

Stateful Adapter Activity Service „EBF fO“ Integration Process Service „ ABCS X“ Orchestrates; “fulfillOrderAsIntegrationProcess” decides on implementation System X

Oracle SOA toolbox SIG SOA 41 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) BPEL based Business Process fulfill Order Service Registry (UDDI) WSDL WSDL

Service D BPEL

SCA Composite “fulfill Order”

Oracle SOA toolbox SIG SOA 43 Decision on implementation at Process Level (preferred when decision rule is business relevant)

BPEL based Business Process if Var 1 > 100.000 fulfill Order as Workflow

else fulfill Order as Internal Integration Process

Adapter Integration Process Service „ ABCS X“ “fulfillOrderAsIntegrationProcess” System X

Adapter Service „ ABCS Y“ System Y

Stateful Workflow „fulfill Order as Workflow“ Pro: Business relevant decision in Process Model

Service D Con: Tighter coupling between process step and implementation (a bit “Anti-SOA”)
