ITU, ISO, IEC collaboration yields fundamental cloud computing standards

ITU, ISO and IEC have approved two new international standards fundamental to the cohesion of cloud computing’s development. The standards provide a terminology foundation to be applied universally across the industry as well as a reference architecture to enable the development of interoperable cloud computing systems and services.

 The new standards are the product of collaboration between ITU-T Study Group 13 (Future networks and cloud) and Subcommittee 38 of ISO/IEC Joint Technical Committee 1 (Information technology). The three international standards bodies are developing baseline standards for cloud computing in the interests of promoting the growth of a competitive market, free of the risk of vendor lock-in and ripe to benefit from economies of scale.

The new standards have been approved as ITU/ISO/IEC common texts and are currently available in pre-published form as they undergo final editing (access restricted to the ITU membership). 

Recommendation ITU-T Y.3500 | International Standard ISO/IEC 17788 “Information technology – Cloud computing – Overview and Vocabulary”

  • An overview of cloud computing accompanied by a set of terms and definitions, providing the terminology foundation for cloud computing standards.

Recommendation ITU-T Y.3502 | International Standard ISO/IEC 17789 “Information technology – Cloud computing – Reference architecture”

  • Specification of the cloud computing reference architecture, which includes cloud computing’s roles and activities as well as its functional components and their relationships.

The new products join a growing series of ITU-T cloud computing standards, adding to:

Two recently approved standards, soon to be available online, provide functional requirements for network as a service ‘NaaS’ (ITU-T Y.3512) and infrastructure as a service ‘IaaS’ (ITU-T Y.3513).

ITU-T cloud computing standardization is providing the requirements and functional architectures of the cloud computing ecosystem, covering inter- and intra-cloud computing and technologies supporting ‘XaaS’ (X as a Service). Particularly relevant to this study is the convergence of telecommunication and computing technology inherent to the emerging cloud computing ecosystem. ITU-T thus develops standards enabling consistent end-to-end, multi-cloud management and the monitoring of services exposed by and across different service providers’ domains and technologies.
