Integration Strategy 1.Service-oriented, message-based integration Reduce inter-dependencies between technologies Robust and scalable in heterogeneous computing environments 2.Virtualization of computing and storage Deploy distributed services where needed Scale to meet demand 3.Support multiple facilities (governance) Avoids central domain of authority Enables new facilities to join the OOI network Keep track of agreements and policy Oceans09 Biloxi, Oct 27, 2009

Common Operating Infrastructure Is the integration & communication environment for all OOI CI subsystem capabilities

Exchange Spaces Oceans09 Biloxi, Oct 27, 2009 Applications communicate through Exchange Spaces Applications must enroll in Exchange Spaces Applications have a unique name in an Exchange Space Applications allocate communication resources before use An Exchange Space Provides secure, reliable, scalable communication Hides routing, addressing and resource allocation

Exchange Space Clients and Resources Oceans09 Biloxi, Oct 27, 2009 Exchange Points are the resources of Exchange Spaces Communicators play the role of Producer, Consumer, and Broker
