3 Signalling aspects

• Interworking between CSC and CSP's monitoring and report component

Test objective is to verify that CSP can provide capabilities monitoring the cloud computing activities
of other functional components throughout the CSP's system and providing reports on the
behaviour of the cloud service provider's system.
• Interworking between CSC and CSP's service access
Test objective is to verify that CSP can provide service access capabilities that provide access offered
by CSP, perform authentication of the CSC and establish authorization to use particular capabilities
of the cloud service. If authorized, the service access capabilities invoke the cloud service
implementation which performs the request.
• Interworking between CSC and CSP's service capabilities

Test objective is to verify that CSP can provide service capabilities which consist of the necessary
software required to implement the service offered to CSC.
• Interworking between CSC and CSP's resource abstraction and control

Test objective is to verify that CSP can provide access to the physical computing resources through
software abstraction and to offer qualities such as rapid elasticity, resource pooling and on-demand
self-service.
• Interworking between CSC and CSP's physical resources
Test objective is to verify that the operational support systems can manage all the elements of the
physical resources (e.g., computing resources, storage resources, and network resources).
For interoperability testing between CSC and CSP, the interoperability testing target should cover the
interworking between CSC and CSP described above. A set of functional test cases need to be developed
based on the corresponding test objectives, and perform functional test to determine if CSC interoperate
with CSP. Figure 3 shows the relationships among functional components and functions for the "use cloud
service" activity between CSC and CSP according to clause A.1.1 of [ITU-T Y.3502].
