2 Cloud Computing management

Figure 9-1 is based on service and resource management chains including the CSC, one or more CSPs, and a
telecommunication operator. The squared boxes with a black outline represent different parties involved in
the common model for E2E cloud computing management.
The term "inter-cloud" is used in accordance with [ITU-T Y.3511] and covers the integration of cloud services
from two or more CSPs.
The term "multi-cloud", as used in this Recommendation, includes holistic E2E management of one or more
cloud service providers providing a given cloud service (see [ITU-T Y.3502], [ITU-T Y.3520], [ITU-T X.1601]).
The term "cloud-aware" is used here to describe the requirement of telecommunication management that
are able to manage cloud-based facilities. This ability could be realized through the use of management
interface "I1" which provides necessary information from the CSP's BSS/OSS to the cloud-aware
telecommunication management system. The management interface "I1" can correspond to a set of SMIs as
described in this Recommendation.
Note that the telecommunication operator may also act as a cloud service provider, see Figure 9-2.

Figure 9-2 – Common model for E2E cloud computing management, with telecommunication
operator acting as a CSP

In this case, the "I1" interface resides within the telecommunication operator.

The common model for E2E cloud computing management does not imply any particular arrangement of
inter-cloud connectivity. For example, the telecommunication operator acting as a CSP could be acting as an
intermediary CSP between the CSC and other cloud services, or in any other inter-cloud role described in
[ITU-T Y.3511]. The management architecture is unaffected by this.

10 Cloud computing management functionalities
This clause identifies functionalities for cloud computing management. The high-level organization of cloud
computing management functionalities presented in Figure 10-1 is based on the management layering
described in clause 8.1 covering customer management, product management, service management, and
resource management.
