ISO/IEC JTC 1/SC 38/WG 3 - Cloud Computing Fundamentals (CCF)

This document specifies concepts used in the field of cloud computing. These concepts expand upon the cloud computing vocabulary defined in ISO/IEC 22123-1 and provide a foundation for other documents that are associated with cloud computing. This document also provides detailed descriptions on the application of these concepts in cloud computing.

This document surveys aspects of the audit of cloud services including: 1) role and responsibilities of parties conducting audit and description of the interactions between the CSC, CSP, and CSN; 2) approaches for conducting audits of cloud services to facilitate confidence in delivering and using cloud services; 3) examples of available frameworks and standards which can be used for audit schemes, for certification, and for authorization. This document builds upon the cloud auditor role as defined in ISO/IEC 17789 and ISO/IEC 22123. This document is applicable to all types and sizes of organizations that need to plan and conduct internal or external audits, and that use, provide and support cloud services. This document is not intended to describe certification or to identify controls that are published elsewhere.

The scope of this document is to describe guidance for using the ISO/IEC 19086-2 metric model, illustrated with examples.

This document provides an overview of and guidance on interactions between cloud service partners (CSNs), specifically cloud service brokers, cloud service developers and cloud auditors, and other cloud service roles. In addition, this document describes how cloud service agreements (CSAs) and cloud service level agreements (cloud SLAs) can be used to address those interactions, including the following: — definition of terms and concepts, and provision of an overview for interactions between CSNs and CSCs and CSPs; — description of types of CSN interactions; — description of interactions between CSNs and CSCs; — description of interactions between CSNs and CSPs; — description of elements of CSAs and Cloud SLAs for CSN interactions, both with CSPs and with CSCs.

This document describes a sample set of cloud service metering elements and billing modes.

This document provides a description of a set of common technologies and techniques used in conjunction with cloud computing. These include: — virtual machines (VMs) and hypervisors; — containers and container management systems (CMSs); — serverless computing; — microservices architecture; — automation; — platform as a service systems and architecture; — storage services; — security, scalability and networking as applied to the above cloud computing technologies.

This document examines the concept of edge computing, its relationship to cloud computing and IoT, and the technologies that are key to the implementation of edge computing. This document explores the following topics with respect to edge computing: — concept of edge computing systems; — architectural foundation of edge computing; — edge computing terminology; — software classifications in edge computing, e.g. firmware, services, applications; — supporting technologies, e.g. containers, serverless computing, microservices; — networking for edge systems, including virtual networks; — data, e.g. data flow, data storage, data processing; — management, of software, of data and of networks, resources, quality of service; — virtual placement of software and data, and metadata; — security and privacy; — real time; — mobile edge computing, mobile devices.

This document provides guidance on the use of international standards as a tool in the development of those policies that govern or regulate cloud service providers (CSPs) and cloud services, and those policies and practices that govern the use of cloud services in organisations. This includes material that explains cloud computing concepts and the role of cloud computing international standards in formulating policies and practices. The document makes references to various international standards. Where possible, these standards are ISO/IEC standards. Where a suitable ISO/IEC standard is not available, references are made to documents published by other WTO-registered standards bodies. As explained in the WTO Agreement on Technical Barriers to Trade (TBT), standards play a vital role in supporting technical regulations and conformity assessment, however this document does not cover matters of trade.

This document establishes common terminology, defines a model for specifying metrics for cloud SLAs, and includes applications of the model with examples. This document establishes a common terminology and approach for specifying metrics. This document is for the benefit of and use for both cloud service providers (CSPs) and cloud service customers (CSCs). This document is intended to complement ISO/IEC 19086-1, ISO/IEC 19086-3 and ISO/IEC 19086-4. This document does not mandate the use of a specific set of metrics for cloud SLAs.

ISO/IEC 19086-3:2017 specifies the core conformance requirements for service level agreements (SLAs) for cloud services based on ISO/IEC 19086‑1 and guidance on the core conformance requirements. This document is for the benefit of and use by both cloud service providers and cloud service customers. ISO/IEC 19086-3:2017 does not provide a standard structure that would be used for cloud SLAs.

ISO/IEC 19086-1:2016 seeks to establish 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) concepts that can be used to build cloud SLAs, and d) terms commonly used in cloud SLAs. ISO/IEC 19086-1:2016 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 cloud 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 cloud service customers when they compare cloud services from different cloud service providers. ISO/IEC 19086-1:2016 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 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. ISO/IEC 19086-1:2016 does not supersede any legal requirement.

This document provides terms and definitions for vocabulary used in the field of cloud computing.
