3.2.3 management service composing function

Management service composing function provides the ability of composing several small management
functions into a new complex management service, so that they can easily provide a new type of
management functionality without having to change the implementation of the component management
functions.

3.2.4 management service deployment function
Management service deployment function provides the ability of deploying required services for a
management task. Each management task may need the support of multiple management services, and for
those services which are not ready for use will appropriately be deployed into some virtualized resources on
the cloud infrastructure.

6 Introduction

The current network management and technologies have the weak point that when new management
requirements are proposed, it is difficult to provide a new management service based on the existing services
using the traditional management technology. It is also hard to compose a small system with simplified
management functions on demand.
Cloud computing has become one of the mainstream technologies used in telecommunication networks as
well as Internet services. Cloud computing technology has the following benefits: high usage rate of physical
resources, reliable service provision, high extensibility, cost efficient, and service on demand etc. When
introducing cloud computing technology into network management domain, it is easy to solve the above
problems, and it will be very flexible to provide new management services.
When introducing cloud into network management, it means that different management function blocks can
be placed into virtual resources, and the virtualized resources can be grouped together to form a composed
management service that are more powerful to provide complex management functions. It is also capable of
dealing with large amount of management data, as distributed computing can be carried out on cheap
servers.
The term management services used in this Recommendation is not the cloud service provided by a network
operator or a cloud operator. Management services are provided by a management system, no matter it is
based on cloud or not. A cloud service is provided by a cloud service provider to end users for resource
virtualization, which provides end users with the cloud computing and/or cloud storing capabilities.

A cloud-aware management system described in [ITU-T Y.3521/M.3070] is a management system which can
be used to manage both traditional telecommunication networks and cloud computing infrastructures.
A cloud-based management system in this Recommendation is a management system which is built using
