Foreword

            Cloud  services  provide  on-demand  access  to     ITU  standards  are  supporting  industry  in
            advanced  ICT  resources,  enabling  innovators  to   navigating this transformation. This compendium
            gain  new  capabilities  without  investing  in  new   of  ITU  cloud  standards  will  provide  ICT  industry
            hardware  or  software.  Cloud  concepts  are  also   players with a valuable point of reference as they
            fundamental to the evolution of ICT networking,     transform  networking  operations  to  take  full
            helping networks to meet the requirements of an     advantage of cloud capabilities.
            increasingly diverse range of ICT applications.

            As  innovation  accelerates  in  fields  such  as  IMT-
            2020/5G  and  the  Internet  of  Things  and  digital
            transformation takes hold in every industry sector,
            the  cloud  ecosystem  will  continue  to  grow  in
            importance  to  companies  large  and  small,  in
            developing as well as developed countries.
            ITU  standards  provide  the  requirements  and
            functional architectures of the cloud ecosystem,
            covering  inter-  and  intra-cloud  computing  and
            technologies supporting ‘XaaS’ (X as a Service).

            These  standards  enable  consistent  end-to-end,
            multi-cloud  management  and  the  monitoring  of
            services  across  different  service  providers’
            domains and technologies – they were developed
            in  view  of  the  convergence  of  telecoms  and
            computing  technologies  that  characterizes  the
            cloud ecosystem.
            Recent years have seen software coming to play a
            key   role   in   network   management    and

            orchestration.  Concepts  rooted  in  datacentre
            networking are transforming telecoms operations,    Chaesub Lee
            with notable examples found in software-defined     Director
            networking and network function virtualization.     ITU Telecommunication Standardization Bureau

            This  convergence  of  telecoms  and  computing
            technology  is  in  full  flight,  with  our  networks
            coming  to  depend  heavily  on  cloud  and  very
            modern  computing,  transport  and  datacentre
            technologies.
            Our  networks  are  transforming  to  become  agile
            all-round players able to perform a wide array of
            specialized  functions.  Cloud  is  central  to  this
            agility,  enabling  the  automated  provisioning  of
            virtualized resources to meet the needs of any ICT
            application.
