This appendix identifies use cases of distributed cloud. The table below shows the template used for the
description of the use cases.

I.1 Use case template

Table I.1 – Template for the description of a use case

Use case

Name Title of use case.
Abstract Overview and features of use case.
Figure Figure to present the use case.
(A unified modeling language (UML)-like diagram is suggested for clarifying relations
between roles).

Pre-conditions Pre-conditions represent the necessary conditions or use cases that should be achieved
(optional) before starting the described use case. (Note)
Post-conditions As the same for pre-condition, the post-condition describes conditions or use cases that will
(optional) be carried out after the termination of a currently described use case.
Requirements The title of requirements derived from the use case. For example:
– Large-scale migration.
NOTE – As dependency may exist among different use cases, pre-conditions and post-conditions are introduced to
help understand the relationships among use cases.
