1. SOA is dead! Isn‟t it?
Or: What is this SOA
thingy?

2. SOA Blueprint and

3. This has (nothing) to
do with SOA: projects

„You know who …“


The Two SOAs
SOA, the Media Acronym SOA, the Architectural Model
(“The Evil Twin”) (“The Good Twin”)
 historically ambiguous  a unique form of
and over-hyped distributed architecture
 was first associated solely  exists to support the
with Web services realization of
service-orientation
 was later stigmatized with
“big bang” project delivery  has distinct
characteristics, principle
 can be ignored
patterns
 cannot be ignored
The key is to understand Service Orientation!

The Paradigm: Service Orientation
The eight Service Orientation Design Principles


SOA is dead – long live Services!

The dream…

In a perfect world, all of your company„s data would
reside on a single database.

None of it would be duplicated, no interfaces would have
to be built, and there„d be a powerful engine on the back
end running a self-tuning, multi-terabype RDBMS that
kicks out sub-second response times.

„The answer is „The answer is
Grid Computing Exalogic Elastic Cloud
Oracle10g RAC“ and Exadata“

*Oracle AIA: Application Integration Architecture

Pains…

High IT costs • Because of heterogeneous application landscapes

Dissatisfaction of users • e.g. because of bad data quality

Too slow reactions on • IT can„t cope with fast changing requirements
change from the outside

Hard replacement of • Often no loose coupling
legacy systems

Fear of change, because • Missing or too old documentation
Implications are unknown • No transparency what„s really happening inside systems

High fault liability • Small system fails, whole process stops


Potential business benefits..
protection of investment • Encapsulation instead of replacement

fullfilment of governance and • Transparency over all systems
compliance requirements

structured • Faster migration to new systems
environment/architecture • Better and saver planing of changes

• Regarding relationships between systems
transparency • Regarding data flows

better communication with • e.g. through introduction of standards
customers/suppliers/B2B

competetive IT • Regarding cost and flexibility

easier readable • A documentation at all…
documentation

business processes over • Use of existing functionality of existing legacy applications
system boundaries

The Big Picture, 3/24/06 Michael L. Brodie

History
 1950 – 2006: Integration = develop then integrate
 1950s-1970s: Simple, manual integration
 1970s-1980s: Distributed Computing (Applications (interoperation), Databases (integrate))
 1990s: Business Driven Integration (increased automation, internet-based computing)
 Concepts: Workflows, Processes, Web,
 Integration solutions blossom & diverge: ETL, EAI, BPM, …
 2000: SOA Emerges
 2000: Web services
 2003: Integration solution evolution accelerates, vendor chaos ensues
 2005: Growth in all integration categories

 2006-2012: Integration = dominant programming model
 • 2001-2010: Wrapping
 • 2005-2010: Re-Engineering
 • 2007-2008: Consolidation
 • 2010-2012: Emergence of SOA Platforms and Solutions
 • 2006-2012: Problem Solving Era: IT/integration relegated to low level func.


Imagine: This is a system …

 Complex system („Black Box“)
 Controls whole business use cases
 Nearly not understandable why that works
 Difficult to maintain und extend
 High rate of redundant hidden functions
 Focus on bulk processing
 Functions in a whole: no segmentation or
sub processes
 Fragile solution (each change can lead to
inconsistency)

 Consequence: Operation and enhancement
lasts long and is expensive


Think about ...

… breaking this system in
small building blocks,
honoring your current and
future requirements …


And think about ...

… reassembling these
elements in new ways for
new requirements……

Import
customer
data

ZipCode
Enter check
Enter ZipCode Save
Supplier
ZipCode check Changes
ID Assign Re-qualify

Then you could …

Degree of
fulfillment

SOA lite Enterprise SOA
 Lightweight Web services  Strategic Platform for Enterprise
 No Enterprise Service Bus (ESB)  Complex Integration settings
 Just an interface description  Use of Middleware Infrastructure
 Point-2-Point Integration  Use of SOA-Suites

APEX or SOA?

 Question in some forum:Why SOA or APEX
Dear ALL, any one can help me, actually I want to know what
is the difference between SOA and APEX and why to choose
APEX or SOA?
 Answer??????
 APEX = tool
 SOA = concept
 You can
 call services from APEX
 expose services from APEX
 integrate with SOA infrastructure (e.g. worklist within APEX)
 use APEX in a SOA world

4 Conclusion


Conclusion
 Integration with and without SOA
 Process Automation with and without SOA
 There is not THE „SOA Project“, only variants
 Term „SOA“ is substitutable
 Concepts do matter
 Embrace Intrinsic Interoperability
 Oracle SOA Suite is a great foundation
 Just start it …
