Use case
Name Inter-cloud computing use case for intermediation
Abstract A CSP intermediates services from other CSPs to provide a service to the CSC.
Actors CSP, CSC

Pre-conditions
(optional)
Post-conditions – A CSP selects a service from other CSPs' services and intermediates them to a CSC.
– A CSP creates a new service by integrating several services in other CSPs and intermediates
them to a CSC.
Requirements – On-demand assignment of cloud resource
– Inter-cloud computing service intermediation

I.9 End-to-end cloud resource management use case

Use case
Name End-to-end cloud resource management use case
Abstract A CSC uses a service offered by multiple CSPs and/or CSNs, one of which supports customer
services. In order to deliver customer services properly, the CSN manages end-to-end health
and QoS of the service offered by a CSP which can integrate several base services offered by
multiple CSPs.
Actors CSC, CSP, CSN
Figure

As shown in the above figure, this problem requires visibility into CSP2's management systems
delivering the voice application service, as well as similar CSP's management systems. When
the voice application customer calls into CSP2 support, then the CSP2 support person should
have visibility into the health and welfare of the CSP1's voice application service, its underlying
cloud infrastructure, as well as the local service provider's network management systems
relevant to the voice application service.
