1.Why Oracle Service Bus 11g ? What are the Key Benefits and Advantages? 1. Service Virtualization :  A core principle of SOA is to ensure that any service consumer can access any service provider - and from any platform. This has been considered as key principle in OSB and it provides robust way of Vitalizing the Service. It's a great value add in SOA Architecture. 2. Loose Coupling :  OSB provides loose coupling by mediating between Service provided and Consumer. Without mediation Service consumer and provider will create dependency to each other. A change in single side provider/consumer will lead to the change dependent consumer/provider respectively. OSB bridges the gap of transport, message format, security technology etc. 3. Location Transparency :  It's a strategy to hide physical location of actual physical location of service endpoints from the Service Consumer. All Service consumers should know only single logical machine & port name for each service. This
