Appendix I

Use case of inter-cloud data management
(This appendix does not form an integral part of this Recommendation.)

This appendix includes inter-cloud data management-related use cases from which the corresponding
functional requirements are derived.

I.1 Use case template

The use cases developed in this appendix adopt the format in Table I.1 for better readability and convenient
material organization.

Table I.1 – Use case template table

Title The title of the use case.
Description Scenario description of the use case.
Roles Roles involved in the use case.
Figure (optional) Figure to explain the use case, but not mandatory.
Pre-conditions (optional) The necessary pre-conditions that should be achieved before starting the use case.
Post-conditions The post-conditions that will be carried out after the termination of current use case.
(optional)
Derived requirements Requirements derived from the use cases, whose detailed description is presented in
the dedicated clause.

I.2 Use case of data use policies in inter-cloud
This use case illustrates data use policies aspect in inter-cloud. The inter-cloud federation pattern used to
illustrate the use case is an example only.

Table I.2 – Data use policies in inter-cloud

Title Data use policies in inter-cloud
Description The CSC requests SaaS, which operates its data in specific countries. The CSP-A (SaaS)
acts in an inter-cloud federation pattern among CPSs (SaaS) and becomes the contact
point for the CSC. The CSP-A (SaaS) determines and validates appropriate data use
policies or principles that allow exchange and operational use of CSC data among the
inter-cloud federation. If the CSP (SaaS) operates out of specific countries, CSC data is
not exchanged.
Roles CSC, CSP (SaaS).
