10、2014 ISO/IEC 17788:2014(E) iv ISO/IEC 2014 All rights reservedForeword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participat

11、e 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 organizations, governmental and

12、 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/IEC Directives, Part 2. The m

13、ain 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 % of the national bodies cas

29、2.5 cloud computing: Paradigm for enabling network access to a scalable and elastic pool of shareable physical or virtual resources with self-service provisioning and administration on-demand. NOTE Examples of resources include servers, operating systems, networks, software, applications, and storag

30、e equipment. 3.2.6 cloud data portability: Data portability (3.2.21) from one cloud service (3.2.8) to another cloud service (3.2.8). 3.2.7 cloud deployment model: Way in which cloud computing (3.2.5) can be organized based on the control and sharing of physical or virtual resources. NOTE The cloud

31、deployment models include community cloud (3.2.19), hybrid cloud (3.2.23), private cloud (3.2.32) and public cloud (3.2.33). 3.2.8 cloud service: One or more capabilities offered via cloud computing (3.2.5) invoked using a defined interface. 3.2.9 cloud service broker: Cloud service partner (3.2.14)

32、 that negotiates relationships between cloud service customers (3.2.11) and cloud service providers (3.2.15). 3.2.10 cloud service category: Group of cloud services (3.2.8) that possess some common set of qualities. NOTE A cloud service category can include capabilities from one or more cloud capabi

33、lities types (3.2.4). 3.2.11 cloud service customer: Party (3.1.6) which is in a business relationship for the purpose of using cloud services (3.2.8). NOTE A business relationship does not necessarily imply financial agreements. 3.2.12 cloud service customer data: Class of data objects under the co

34、ntrol, by legal or other reasons, of the cloud service customer (3.2.11) that were input to the cloud service (3.2.8), or resulted from exercising the capabilities of the cloud service (3.2.8) by or on behalf of the cloud service customer (3.2.11) via the published interface of the cloud service (3.

35、2.8). NOTE 1 An example of legal controls is copyright. NOTE 2 It may be that the cloud service (3.2.8) contains or operates on data that is not cloud service customer data; this might be data made available by the cloud service providers (3.2.15), or obtained from another source, or it might be pub

36、licly available data. However, any output data produced by the actions of the cloud service customer (3.2.11) using the capabilities of the cloud service (3.2.8) on this data is likely to be cloud service customer data (3.2.12), following the general principles of copyright, unless there are specifi

37、c provisions in the cloud service (3.2.8) agreement to the contrary. 3.2.13 cloud service derived data: Class of data objects under cloud service provider (3.2.15) control that are derived as a result of interaction with the cloud service (3.2.8) by the cloud service customer (3.2.11).

It can also include information about the numbers of authorized users and their identities. It can also include any configuration or customization data,

39、where the cloud service (3.2.8) has such configuration and customization capabilities. BS ISO/IEC 17788:2014 ISO/IEC 17788:2014 (E) Rec. ITU-T Y.3500 (08/2014) 3 3.2.14 cloud service partner: Party (3.1.6) which is engaged in support of, or auxiliary to, activities of either the cloud service provid

40、er (3.2.15) or the cloud service customer (3.2.11), or both. 3.2.15 cloud service provider: Party (3.1.6) which makes cloud services (3.2.8) available. 3.2.16 cloud service provider data: Class of data objects, specific to the operation of the cloud service (3.2.8), under the control of the cloud se

41、rvice provider (3.2.15). NOTE Cloud service provider data includes but is not limited to resource configuration and utilization information, cloud service (3.2.8) specific virtual machine, storage and network resource allocations, overall data centre configuration and utilization, physical and virtu

42、al resource failure rates, operational costs and so on. 3.2.17 cloud service user: Natural person, or entity acting on their behalf, associated with a cloud service customer (3.2.11) that uses cloud services (3.2.8). NOTE Examples of such entities include devices and applications. 3.2.18 Communicati

43、ons as a Service (CaaS): Cloud service category (3.2.10) in which the capability provided to the cloud service customer (3.2.11) is real time interaction and collaboration. NOTE CaaS can provide both application capabilities type (3.2.1) and platform capabilities type (3.2.31). 3.2.19 community clou

44、d: Cloud deployment model (3.2.7) where cloud services (3.2.8) exclusively support and are shared by a specific collection of cloud service customers (3.2.11) who have shared requirements and a relationship with one another, and where resources are controlled by at least one member of this collectio

45、n. 3.2.20 Compute as a Service (CompaaS): Cloud service category (3.2.10) in which the capabilities provided to the cloud service customer (3.2.11) are the provision and use of processing resources needed to deploy and run software. NOTE To run some software, capabilities other than processing resou

46、rces may be needed. 3.2.21 data portability: Ability to easily transfer data from one system to another without being required to re-enter data. NOTE It is the ease of moving the data that is the essence here. This might be achieved by the source system supplying the data in exactly the format that

47、is accepted by the target system. But even if the formats do not match, the transformation between them may be simple and straightforward to achieve with commonly available tools. On the other hand, a process of printing out the data and rekeying it for the target system could not be described as “e

48、asy“. 3.2.22 Data Storage as a Service (DSaaS): Cloud service category (3.2.10) in which the capability provided to the cloud service customer (3.2.11) is the provision and use of data storage and related capabilities.
