2. AGENDA
Is SOA dead?
What will drive SOA in the future
WSo2 Con 2011, Colombo
Open source SOA capabilities, WSO2 experience
Future computing with SOA
High Performance Architecture
Semantics or Context driven Architecture
Event & time driven Architecture
Enterprise “Future”

3. IS SOA DEAD?
Infamous article – enflamed passions – how could
it be?
WSo2 Con 2011, Colombo
Burton Group's Anne Thomas Manes on SOA
Can a concept die?
Was it misunderstood?
Did someone highjack SOA?
Is redemption possible?
If not will the world end?

4. WHAT WILL DRIVE SOA IN FUTURE
Let’s get some facts straight
Customers are not gullible
Fool them once … but try twice you risk losing them!
WSo2 Con 2011, Colombo
Domain experts are tech savvy – utilize their skills
From eXcel spreadsheets to Business process
modeling, they know it all
Customers understand what it takes to build
software
They know waterfall does not work!
They know Services are important
They can no longer afford to work in silos. There is
pressure to do things right
They know not every thing has to be purchased
Customers know there is open source technology, they need 4
serious help here
5. OPEN SOURCE SOA CAPABILITIES
So you thing SOA is not possible with open
source … think again

6. FUTURE COMPUTING – IS SOA ENOUGH?
Customers need Customers!
And Customers are everywhere.
They will not call you … you need to connect with them?
WSo2 Con 2011, Colombo
How is that possible?
Cloud, Mobile, Social networking …. ?
But these are just infrastructures or channels
SOA will have to couple itself with future computing styles
High performance architecture
Intelligent (Semantic?) data processing
Event & time driven architectures
SOA style will have to address this
Canonical modeling – design time tools & run time
transformations
Robust Infrastructure services
1:many deployment styles – EAI, Federation (Domain or
Central) 6
7. WHAT IS HIGH PERFORMANCE
ARCHITECTURE?
SLA and Response times is only part of the
problem
The real challenge is how to create a efficient mix
WSo2 Con 2011, Colombo
of high performance pipes within enterprise and
robust integration (with better security) for
external world interaction
Another challenge is integration of plethora of
technology choices
Microsoft, Java (Legacy)
Deeply Entrenched (C++, PHP, Perl, Python)
Promising (Groovy, Erlang)
Exposing everything as a SOAP service is not the
only acceptable solution often times 7
8. WHO HAS BUILT HIGH PERFORMANCE
INFRASTRUCTURES?
eBAY, Facebook, Google etc
Thrift architecture
WSo2 Con 2011, Colombo
High performance serialization
Multi language support
Client & Server size code generation
IDL to define message structures & operations

11. SEMANTICS POWERED ARCHITECTURE
“Book me a holiday next weekend somewhere warm, not too far
away, and where they speak French or English”
• Has meaning or semantic(s) – namely a person wants to go on a holiday
WSo2 Con 2011, Colombo
Can Semantics be Cancer Ontology

machines can process? syndrome
What is Ontology?
Why is it important T-Cell

Medical: Drug Detect drug or disease based on name, chemical

What is an Event?
What is a complex event?
WSo2 Con 2011, Colombo
Events in real world – some examples
Event and time – what’s the connection?
What class of applications can benefit the most

17. SAMPLE SCENARIOS
Financial:
Tracks transactions that are traded at a level exceeding
Market a pre-determined % threshold away from pre-defined
Surveillance benchmark
Retail :
Items coming and leaving warehouse can be monitored using RFID tags
Automated
Automatically order is placed to the supplier when items reaches below the
threshold Supply Chain
Financial:
Market Retail Larger than average deposit made by the customer. Check if this is in
WSo2 Con 2011, Colombo
preparation of a larger purchase and the if the customer is looking for a
Banking
loan or investment vehicle
Transportation:
Discover fraudulent activity by detecting patterns among events.: Single ID Security and
card used twice to enter subway in less than 5 secs. := alert security for Fraud Detection
piggybacking
Financial: Identifying fraud with credit card: purchase with same credit card
Market Fraud happened in London and Hong Kong within 6 hours (Minimum travel time
Detection between London and Hong Kong is more than 10 hours)
Energy and
Reduce false positive alarms: When 15 alarms are received within any 5 second Telecommunicatio
window, but less than 5 similar alarms detected within 30 seconds, then do ns: Alarm
nothing Correlation
Financial:
Market Anti Associating multiple transfers that individually might not seem
Money suspicious.

Financial:
Automate stock trading based on market movement: if, within any 20 second Algorithmic
window, StockB rises by more than 2% and StockA does not, then automatically
buy StockA.

19. WHY IS DATA MODELING IMPORTANT?
Canonical data model is not new but there is
renewed interest in it
WSo2 Con 2011, Colombo
Is it possible to model data at rest and data in
motion and keep everything in sync?
What technology choices are available here
E2E modeling & integration – More useful for EAI
style of integration
Focus on modeling but customize integration for
better performance – here SOA can help
