Appendix III

Alignment analysis with [ITU-T Y.3513]
(This appendix does not form an integral part of this Recommendation.)

[ITU-T Y.3513] introduces the concept of Infrastructure as a Service (IaaS) and describes its functional
requirements. As one of the cloud computing service categories, IaaS provides infrastructure capabilities as
services by cloud service providers. It is necessary to ensure that the test cases cover requirements in [ITU-T
Y.3513]. Alignment analysis with requirements in [ITU-T Y.3513] is provided as Table III.1.

Functional requirements in [ITU-T Y.3513] Test objects in this Recommendation

1 7 Functional – It is recommended that the IaaS CSP Too general, not involved.
requirement provides to the CSC IaaS functions, such as a
composition of processing, storage, and
networking resources with service logic,
specific service level agreements (SLAs) and
charging model.

2 – It is required that the IaaS CSP provides the Too general, not involved.
CSC with operations handling mechanisms
related to provisioned infrastructure
resources, such as assign, modify, query and
release.

3 – It is recommended that the IaaS CSP Too general, not involved.
provides status information about the
infrastructure in response to queries from
the CSC.

4 – It is recommended that the IaaS CSP Too general, not involved.
provides a template to the CSC, related to
instantiation of infrastructure, which allows
for provision processing, storage and
networking resources that could be
implemented based on the configuration.

5 – It is recommended that the IaaS CSP Too general, not involved.
provides the CSC with operations handling
mechanisms related to infrastructure
templates to allow modification of
infrastructure, such as upload, update,
disable, enable, query or release.
6 7.1 – It is required that the IaaS CSP provides Too general, not involved.
Computing computing functions with specific SLAs and
service charging model to the CSC.
