IS SOA DEAD?

Infamous article – enflamed passions – how could

it be?

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?

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!

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

serious help here4

OPEN SOURCE SOA CAPABILITIES

So you thing SOA is not possible with open

source … think again

FUTURE COMPUTING – IS SOA ENOUGH?

Customers need Customers!

And Customers are everywhere.

They will not call you … you need to connect with them?

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

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 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

Thrift architecture

High performance serialization

Multi language support

Client & Server size code generation

IDL to define message structures & operations

SEMANTICS POWERED ARCHITECTURE

Can Semantics be described as domain specific ontology's which machines can process?

What is Ontology?

Why is it important

Where it is most applicable

SOA & Semantics – How can they benefit from each other

SAMPLE SCENARIOS

Discover fraudulent activity by detecting patterns among events.: Single ID

card used twice to enter subway in less than 5 secs. := alert security for

piggybacking

Larger than average deposit made by the customer. Check if this is in

preparation of a larger purchase and the if the customer is looking for a

loan or investment vehicle

Tracks transactions that are traded at a level exceeding

a pre-determined % threshold away from pre-defined

benchmark

Associating multiple transfers that individually might not seem

suspicious.

Identifying fraud with credit card: purchase with same credit card

happened in London and Hong Kong within 6 hours (Minimum travel time

between London and Hong Kong is more than 10 hours)

Items coming and leaving warehouse can be monitored using RFID tags

Automatically order is placed to the supplier when items reaches below the

threshold

WHY IS DATA MODELING IMPORTANT?

Canonical data model is not new but there is

renewed interest in it

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
