2 Cloud Computing management

With the convergence of information technology (IT) and communications technology (CT) industries, cloud
computing is being adopted in telecommunication infrastructures. Telecommunication operators deliver
cloud services, and also apply cloud computing technologies for the optimization of their telecommunication
service platforms and telecommunication support systems.

[ITU-T M.3070] has defined a service management interface (SMI)-based common model for end-to-end
(E2E) cloud computing management, which is described in Figure 6-1. In this model, a cloud-aware
telecommunication management system can manage cloud-based facilities through the management
interface "I1" which can correspond to a set of SMIs.

telecommunication operator acting as a CSP (after [ITU-T M.3070])

A cloud-aware telecommunication management system can manage both telecommunication services and
cloud services in a consistent manner. Although the management layering could be the same as the
traditional telecommunication management layering, with the introduction of cloud computing, there are
still new requirements for cloud-aware telecommunication management. This Recommendation addresses
the requirements of comprehensive service management in a cloud-aware telecommunication management
system.

The relationship between cloud service management and service management in a cloud-aware
telecommunication management system is also illustrated in Figure 6-1. The cloud service management is
located in business support system(BSS)/operations support system (OSS) (marked by the red rectangle in
Figure 6-1) which belongs to the cloud service provider (CSP), and the service management in the cloud-
aware telecommunication management system (marked by the yellow rectangle in Figure 6-1) which belongs
to telecommunication operator. As an important aspect of cloud service management, cloud service lifecycle
management (see [ITU-T Y.3522]) is also located in BSS/OSS which belongs to CSP.

7 General requirements for service management in cloud-aware telecommunication management
system

As a cloud-aware telecommunication management system, the difference with a traditional
telecommunication management system is it could support comprehensive management for
telecommunication services, cloud services and TC-hybrid services which consist of both telecommunication
and cloud service components.
