National bodies that are membe

16、rs of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international orga

17、nizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IE

18、C Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 %

19、 of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 17789 was prepared by Joint Technical Committ

26、ndamental concepts or properties of a system in its environment embodied in its elements, relationships and in the principles of its design and evolution. The following term is defined in ISO/IEC 29100: 3.1.2 personally identifiable information (PII): Any information that (a) can be used to identify

27、 the PII principal to whom such information relates, or (b) is or might be directly or indirectly linked to a PII principal. NOTE To determine whether a PII principal is identifiable, account should be taken of all the means which can reasonably be used by the privacy stakeholder holding the data, o

28、r by any other party, to identify that natural person. 3.2 Terms defined in this Recommendation | International Standard This Recommendation | International Standard defines the following terms: 3.2.1 activity: A specified pursuit or set of tasks. 3.2.2 cloud service product: A cloud service, allied

29、 to the set of business terms under which the cloud service is offered. NOTE Business terms can include pricing, rating and service levels. 3.2.3 functional component: A functional building block needed to engage in an activity (clause 3.2.1), backed by an implementation. DIN ISO/IEC 17789:2017-07 5

30、 3.2.4 peer cloud service: A cloud service of one cloud service provider which is used as part of a cloud service of one or more other cloud service providers. 3.2.5 peer cloud service provider: A cloud service provider who provides one or more cloud services for use by one or more other cloud servi

31、ce providers as part of their cloud services. 3.2.6 product catalogue: A listing of all the cloud service products (clause 3.2.2) which cloud service providers make available to cloud service customers. 3.2.7 role: A set of activities (clause 3.2.1) that serves a common purpose. 3.2.8 service catalo

35、fundamental characteristics of cloud computing systems; to specify basic cloud computing activities and functional components, and describe their relationships to each other and to the environment; to identify principles guiding the design and evolution of the CCRA. The CCRA supports the following i

36、mportant standardization objectives: to enable the production of a coherent set of international standards for cloud computing; to provide a technology-neutral reference point for defining standards for cloud computing; to encourage openness and transparency in the identification of cloud computing

37、benefits and risks. The CCRA focuses on the requirements of “what“ cloud services provide and not on “how to“ design cloud-based solutions and implementations. The CCRA does not represent the system architecture of a specific cloud computing system, although it could put constraints on a specific sy

38、stem. The CCRA is not tied to any specific vendor products, services or reference implementation; nor does it define prescriptive solutions that inhibit innovation. The CCRA is also intended to: facilitate the understanding of the operational intricacies of cloud computing; illustrate and provide un

39、derstanding of various cloud services and their provisioning and use; provide a technical reference to enable the international community to understand, discuss, categorize and compare cloud services; be a tool for describing, discussing, and for developing a system-specific architecture using a com

40、mon framework of reference; facilitate the analysis of candidate standards in areas including security, interoperability, portability, reversibility, reliability and service management, and support analysis of reference implementations.

41、his Recommendation | International standard defines a CCRA that can serve as a fundamental reference point for cloud computing standardization and which provides an overall framework for the basic concepts and principles of a cloud computing system. This clause provides an overview of the architectu

42、ral approaches that are used in this Recommendation | International standard. 7.1 CCRA architectural views Cloud computing systems can be described using a viewpoint approach. Four distinct viewpoints are used in the CCRA (see Figure 7-1): user view; functional view; implementation view; and deploym

43、ent view. Figure 7-1 Transformations between architectural views Table 7-1 provides a description of each of these views. Table 7-1 CCRA views CCRA view Description of the CCRA view Scope User view The system context, the parties, the roles, the sub-roles and the cloud computing activities Within sc

45、ice are technically implemented within already existing infrastructure elements or within new elements to be introduced in this infrastructure Out of scope NOTE While details of the user view and functional view are addressed within this Recommendation | International Standard, the implementation an

46、d deployment views are related to technology and vendor-specific cloud computing implementations and actual deployments, and are therefore out of the scope of this Recommendation | International Standard. Figure 7-2 shows the transition from the user view to the functional view. Details are presente
