Cloud computing

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.

ISO/IEC 19944:2017

- extends the existing cloud computing vocabulary and reference architecture in ISO/IEC 17788 and ISO/IEC 17789 to describe an ecosystem involving devices using cloud services,

- describes the various types of data flowing within the devices and cloud computing ecosystem,

- describes the impact of connected devices on the data that flow within the cloud computing ecosystem,

- describes flows of data between cloud services, cloud service customers and cloud service users,

- provides foundational concepts, including a data taxonomy, and

- identifies the categories of data that flow across the cloud service customer devices and cloud services.

ISO/IEC 19944:2017 is applicable primarily to cloud service providers, cloud service customers and cloud service users, but also to any person or organization involved in legal, policy, technical or other implications of data flows between devices and cloud services.

ISO/IEC 19941:2017 specifies cloud computing interoperability and portability types, the relationship and interactions between these two cross-cutting aspects of cloud computing and common terminology and concepts used to discuss interoperability and portability, particularly relating to cloud services.

ISO/IEC 19941:2017 is related to other standards, namely, ISO/IEC 17788, ISO/IEC 17789, ISO/IEC 19086‑1, ISO/IEC 19944, and in particular, references the cross-cutting aspects and components identified in ISO/IEC 17788 and ISO/IEC 17789 respectively.

The goal of this document is to ensure that all parties involved in cloud computing, particularly CSCs, CSPs and cloud service partners (CSNs) acting as cloud service developers, have a common understanding of interoperability and portability for their specific needs. This common understanding helps to achieve interoperability and portability in cloud computing by establishing common terminology and concepts.

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.

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.

Standardization in the areas of Cloud Computing and Distributed Platforms including:

• Foundational concepts and technologies,
• Operational issues, and
• Interactions among Cloud Computing systems and with other distributed systems

SC 38 serves as the focus, proponent, and systems integration entity on Cloud Computing, Distributed Platforms, and the application of these technologies. SC 38 provides guidance to JTC 1, IEC, ISO and other entities developing standards in these areas.

Recommendation ITU-T M.3070/Y.3521 presents the conceptual view and the common model of end-to-end (E2E) cloud computing management based on the service management interface (SMI) and cloud computing reference architecture, from the perspective of the telecommunications industry.

Recommendation ITU-T Y.3520 presents general concepts of end to end resource management in cloud computing; a vision for adoption of cloud resource management in a telecommunication-rich environment; and multi-cloud, end to end resource management for cloud services, i.e., management of any hardware and software used in support of the delivery of cloud services.

The present document specifies the network acceleration related interfaces supported over the Vn-Nf reference point of the NFV architectural framework between a VNF and a dedicated switch controlled by that VNF. The present document also defines information elements exchanged over those interfaces.
 
The present document is built on the use of the Dynamic Optimization of Packet Flow Routing (DOPFR) mechanism (see use case described in ETSI GS NFV-IFA 001). Based on DOPFR, the present document aims to design a common interface allowing a Network Intensive VNF (NI-VNF) to accelerate its data plane processing on a dedicated switch.

Cloud computing is a 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. The cloud computing paradigm is composed of key characteristics, cloud computing roles and activities, cloud capabilities types and cloud service categories, cloud deployment models and cloud computing cross cutting aspects.

This Recommendation | International Standard provides an overview of cloud computing, and defines related terms.
The terms and definitions provided in this Recommendation | International Standard:
– cover commonly used terms and definitions in cloud computing standards;
– will not cover all terms and definitions used in cloud computing standards; and
– do not preclude the definition of additional terms for use in cloud computing standards.

Cloud computing is a 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. See Rec. ITU-T Y.3500 | ISO/IEC 17788.  The CCRA presented in this Recommendation | International Standard provides an architectural framework that is effective for describing the cloud computing roles, sub-roles, cloud computing activities, cross-cutting aspects, as well as the functional architecture and functional components of cloud computing.
