ISO publishes cloud standards
The International Standards Organization and the International Electrotechnical Commission, together with the International Telecommunication Union, released two International Standards for cloud computing.
ISO/IEC 17788, Cloud computing – Overview and vocabulary, provides definitions of common cloud computing terms, including those for cloud service categories such as Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). It also specifies the terminology for cloud deployment models such as “public” and “private” cloud. ISO/IEC 17788 draws on definitions developed by the National Institute of Standards and Technology, including SP 800-145: The NIST Definition of Cloud Computing, SP 800-146: Cloud Computing Synopsis and Recommendations and SP 500-292: NIST Cloud Computing Reference Architecture.
More technical in nature, ISO/IEC 17789, Cloud computing – Reference architecture, contains diagrams and descriptions of how the various aspects of cloud computing relate to one another.
The new standards from ISO give a largely similar definition, choosing to call cloud computing an “evolving paradigm,” according to CloudTech. The ISO’s assessment of cloud’s key concepts – including broad network access, measured service, multi-tenancy, on-demand self-service, rapid elasticity and scalability and resource pooling – ring true with the NIST standards, wrote CloudTech’s James Bourne.
But whereas the NIST standards define PaaS, SaaS and IaaS, ISO’s new document includes seven distinct cloud service categories, including network as a service (NaaS) and data storage as a service (DSaaS).
Similarly, ISO expands on NIST’s 2011 definition on cloud deployment models, adding community cloud to public, private and hybrid, Bourne wrote.
The complete text of the ISO/IEC 17788 standard can be purchased for around $60 and ISO/IEC 17789 for around $187.
