2. "SOA en BPEL" Is Service Orchestratie een overdraagbare aandoening?
Sandor Nieuwenhuijs
Good morning everybody. It is a great pleasure to be with you today.
My name is Edwin Khodabakchian and I am VP of Product Development

3. No Application is an Island
Example: Modern Web Application
Application for the provisioning and activation of cell phone plans
Telco Activation Services
SMS Activation Manager
GPRS Activation Manager
China Roaming Activation Manager
Application Server
Automatic Payment Approval
New Plan Selection
User Interface
There is an increasing demand for new applications to integrate existing systems. At the same time the IT infrastructure is becoming increasingly heterogeneous.

4. Java + JCA + JMS + EAI = “Not Enough”
Java Services (EJB)
Messaging Destinations (JMS)
Legacy Applications (JCA, adapters)

Orchestration Today
Not enough metadata
 Not tool friendly
Proprietary flow languages
 Rare skill sets, consulting
Hard Wired/Code
 Rigid, difficult to change
Incompatible Infrastructures
 Difficult to manage and scale

9. …Can Offer Optimized Bindings

The key message here is that SOA is not a big bang but rather an evolutionary approach for rationalizing and enhancing interoperability/reuse among your existing IT assets. The technical enabler is that WSDL separates the definition of the service in an interface and a binding, allowing the binding to be optimized (transport and data representation) while keeping the interface standard/tool friendly.
