19、19086-1:2016ISO/IEC 19086-1:2016(E) Foreword 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 participate in the development of In

20、ternational 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 non-governmental, in liai

21、son 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. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part

22、 1. In particular the different approval criteria needed for the different types of document should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elemen

23、ts 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. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations r

24、eceived (see www.iso.org/patents). Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement. For an explanation on the meaning of ISO specific terms and expressions related to conformity assessment, as well as information about ISO

ISO/IEC 19086 builds on the cloud com

27、puting concepts defined in ISO/IEC 17788 and ISO/IEC 17789. This document establishes a common framework for helping organizations to understand the purpose of all the parts of ISO/IEC 19086 and the relationships between those parts. It also identifies other documents that have relationships with IS

28、O/IEC 19086 and which are useful in understanding cloud SLAs. This document can be used by any organization or individual involved in the creation, modification or understanding of a cloud service level agreement which conforms to ISO/IEC 19086. The cloud SLA should account for the key characteristi

29、cs of a cloud computing service and needs to facilitate a common understanding between cloud service providers and cloud service customers. In particular, it defines the following fundamental concepts of the cloud SLA framework: Cloud Service Agreement (CSA) Cloud Service Level Agreement (SLA) Cloud

30、 Service Level Objectives (SLO) Cloud Service Qualitative Objectives (SQO) This document also describes the content areas and components that consist of a list of SLOs and SQOs. ISO/IEC 19086-2 provides the metrics model to be used for creating metrics used in SLOs and SQOs. ISO/IEC 19086-3 provides

31、 the core conformance requirements derived from the SLOs and SQOs defined in this document. ISO/IEC 19086-4 builds upon the foundational concepts and definitions described by this document by describing specific components and the conformance requirements for SLOs and SQOs in the area of Security an

32、d Privacy. More specifically, this document a) promotes cohesion between the parts of ISO/IEC 19086 by explaining the concepts and terminology used across all parts, b) contributes to the understanding of ISO/IEC 19086 by clarifying the relationships between all the parts, and c) provides an overvie

33、w of other International Standards which can be used in combination with ISO/IEC 19086.

36、h a set of common cloud SLA building blocks (concepts, terms, definitions, contexts) that can be used to create cloud Service Level Agreements (SLAs). This document specifies a) an overview of cloud SLAs, b) identification of the relationship between the cloud service agreement and the cloud SLA, c)

37、 concepts that can be used to build cloud SLAs, and d) terms commonly used in cloud SLAs. This document is for the benefit and use of both cloud service providers and cloud service customers. The aim is to avoid confusion and facilitate a common understanding between cloud service providers and clou

38、d service customers. Cloud service agreements and their associated cloud SLAs vary between cloud service providers, and in some cases different cloud service customers can negotiate different contract terms with the same cloud service provider for the same cloud service. This document aims to assist

39、 cloud service customers when they compare cloud services from different cloud service providers. This document does not provide a standard structure that can be used for a cloud SLA or a standard set of cloud service level objectives (SLOs) and cloud service qualitative objectives (SQOs) that will

40、apply to all cloud services or all cloud service providers. This approach provides flexibility for cloud service providers in tailoring their cloud SLAs to the particular characteristics of the offered cloud services. This document does not supersede any legal requirement. 2 Normative references The
