Cloud Computing Portability and Interoperability : Preface

The Open Group

The Open Group is a global consortium that enables the achievement of business objectives through IT standards. With more than 400 member organizations, The Open Group has a diverse membership that spans all sectors of the IT community – customers, systems and solutions suppliers, tool vendors, integrators, and consultants, as well as academics and researchers – to:

• Capture, understand, and address current and emerging requirements, and establish policies and share best practices
• Facilitate interoperability, develop consensus, and evolve and integrate specifications and open source technologies
• Offer a comprehensive set of services to enhance the operational efficiency of consortia
• Operate the industry’s premier certification service

Further information on The Open Group is available at www.opengroup.org.

The Open Group publishes a wide range of technical documentation, most of which is focused on development of Open Group Standards and Guides, but which also includes white papers, technical studies, certification and testing documentation, and business titles. Full details and a catalog are available at www.opengroup.org/bookstore.

Readers should note that updates – in the form of Corrigenda – may apply to any publication. This information is published at www.opengroup.org/corrigenda.

This Document

This document is The Open Group Guide to Cloud Computing Portability and Interoperability. It has been developed and approved by The Open Group.

The Guide explains the major portability and interoperability issues that arise when cloud computing is used. It makes recommendations to customers on how best to achieve portability and interoperability when working with current cloud products and services, and it makes recommendations to suppliers and standards bodies on how standards and best practice should evolve to enable greater portability and interoperability in future.

It covers all forms of cloud computing, as described in the NIST Cloud Computing definition [NIST DEFINITION].

The intended audience includes:

• Architect practitioners designing or using cloud computing solutions
• Vendors and providers of cloud computing seeking guidance on interoperating issues and practices
• Customers and buyers of cloud computing services seeking guidance on interoperability issues and practices
• Governments, non-governmental organizations (NGOs), and commercial industry bodies that have specific vertical industry or cross-industry issues and challenges and seek guidance on cloud computing interoperability
• Standards organizations and other bodies seeking a point of view from The Open Group on cloud computing portability and interoperability
