Which statement best describes how Service-Oriented Integration (SOI) differs from traditional Enterprise Application Integration (EAI)?
Correct Answer: E
Explanation/Reference:
Enterprise Application Integration (EAI) is an approach for integrating multiple applications. EAI products are built around messaging products and are deployed in either a hub-and-spoke architecture or in a bus architecture.
Some argue that service-oriented integration is actually a form EAI. This is not correct.
EAI is an application-oriented architecture. EAI provides the mechanism to have applications interact to share data and functionality. Service-oriented integration adds the concept (and concrete deployment) of SOA Services that are separate and distinct, with a lifecycle that is independent, from any application in the computing environment.
