Why OSB?

This can be handy if we want to use the OSB for adding an additional abstraction layer

to apply service virtualization. If all the service consumers no longer access the external

services directly, but only through the OSB proxy-service, a lot of the features of OSB can

be used transparently by a service consumer, such as SLA monitoring and alerting, service

pooling and throttling, or message validation. This directly supports the main goal of service

virtualization—adding operational agility.
