Appendix I

Relationship between DaaS logical components and cloud
computing reference architecture

(This appendix does not form an integral part of this Recommendation.)

This appendix provides the relationship between DaaS logical components [ITU-T Y.3503] and cloud
computing reference architecture in [ITU-T Y.3502].

The relationship between DaaS logical components and cloud computing reference architecture can be done
in two steps.

The first step is the mapping between DaaS logical components and DaaS functions in clause 6. Based on
clause 6, each corresponding functions of DaaS for the DaaS logical components in [ITU-T Y.3503] is described
in Table 6-1.

The second step is the mapping between DaaS functions and functional components of cloud computing
reference architecture. This mapping is described in Figure 8-1.

Therefore, the possible mapping between DaaS logical components and functional components in cloud
computing reference architecture is shown in Figure I.1.
