            −       Accounting and charging: It is recommended that the cloud services provided by a CSP support
                    various accounting and charging models and policies.
            −       Efficient service deployment: It is recommended that the cloud services provided by a CSP enable
                    the efficient use of resources for service deployment.
            −       Interoperability:  It  is  recommended  that  the  cloud  services  provided  by  a  CSP  comply  with
                    appropriate specifications and/or standards for allowing these systems to work together.
            −       Portability: It is recommended that the cloud services provided by a CSP support the portability of
                    software assets and data of cloud service customers (CSCs) with minimum disruption.
            −       Service access: A CSP is recommended to provide CSCs with access to cloud services from a variety
                    of  user  devices.  It  is  recommended  that  CSCs  be  provided  with  a  consistent  experience  when
                    accessing cloud services from different devices.
            −       Service  availability,  service  reliability  and  quality  assurance:  It  is  recommended  that  the  CSP
                    provides end-to-end quality of service assurance, high levels of reliability and continued availability
                    of cloud services according to the service level agreement (SLA) with the CSC.

            7       Overview of cloud computing standard roadmap

            7.1     Introduction to standards development organizations (SDOs) for cloud computing
            7.1.1   ITU-T SG13

            Study  Group  13  is  responsible  for  studies  relating  to  the  requirements,  architectures,  capabilities  and
            mechanisms  of  future  networks  including  studies  relating  to  service  awareness,  data  awareness,
            environmental awareness and socio-economic awareness of future networks. It is responsible for studies
            relating  to  cloud-computing  technologies,  big  data,  virtualization,  resource  management,  reliability  and
            security aspects of the considered network architectures.
            –       Q17/13 (Requirements, ecosystem, and general capabilities for cloud computing and big data)
                    The primary focus of this Question is to provide the necessary overall frameworks, definitions and
                    ecosystems, including requirements and capabilities, related to the integration or support of cloud
                    computing  and  big  data  models  and  technologies  in  telecommunication  ecosystems.  Also  the
                    relationship  between  cloud  computing  and  big  data  is  developed.  This  Question  is  intended  to
                    develop new Recommendations for:
                    •   cloud computing and big data definitions, overview, ecosystem and use cases;

                    •   cloud computing and big data requirements and capabilities;
                    •   requirements for interoperability data portability and exchange information in cloud computing
                        and big data;
                    •   relationship between cloud computing and big data;
            –       Q18/13 (Cloud functional architecture, infrastructure and networking)
                    The  main  focus  of  this  Question  is  to  provide  cloud  computing  architectures,  cloud  computing
                    infrastructure  and  cloud  networking  views  related  to  the  integration  and  support  of  the  cloud
                    computing  paradigm  and  technologies  in  telecommunication  ecosystems.  Another  focus  of  this
                    Question is to provide big data architectures related to the integration and support of the big data
                    paradigm and technologies in telecommunication ecosystems.
                    This Question is intended to develop new Recommendations for:
                    •   cloud computing functional architectures supporting cloud service categories (e.g., NaaS, IaaS,
                        PaaS, BDaaS and XaaS);
                    •   cloud computing functional architectures of inter-cloud;
                    •   cloud computing infrastructure including cloud networking aspects (e.g., for the  support of
                        network slicing);
                    •   big data functional architectures including big data exchange functional architecture and cloud-
                        computing-based big data architecture.
