            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
