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“


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.


SOA Blueprint2


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


Vision: Adaptive Enterprise Computing


SOA Blueprint


Another „AIA“: Accidental Integration Architecture


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

Objectives:

• Provide all Oracle and BEA customers with a seamless upgrade path

• Use Oracle Service Bus as the vehicle to deliver new ESB features

• Use OESB in hot-pluggable environments, for mediation and internal apps AIA use cases

4 Tools in specific contexts

27 / 19. Sept. 2008/

Things BPM

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


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


Nature of many projects:Organizational context local; rather workflow than BPM

Redundant functionality

Fulfillment SAP-CRM Billing

Internal processes (task driven,

no interaction with other silos)

Silo specific functionality


.. 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


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

-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

-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

Enterprise BPM

These differefferent contexts have impacts on the feasible tools and their usage!


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 and ESB necessary for

service virtualization and reuse

No UDDI is necessary for

data stewardship

Business Rule Engine not

justified, some

developers might play

with it.


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

Call services along a chain

Simple enrichment

do routing (if it depends on

message content)

Application Business Connector Services

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 ...

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

• Oracle has a best-in-class SOA toolbox…

• …just needs a better, holistic SOA strategy communication

• Adhere to the SOA Blueprint!

• Know your toolbox very well!

• Know the right tool for the right context!

• Don„t get stuck in one learned solution, investigate the tradeoffs!
