仮想化の未来：新たな動向とベンダー環境の進化

原文目次

Abstract

The Future of Virtualization report examines one of the biggest trends in recent IT history: virtualization. The promise of virtualization technology - whether applied to the server, storage, client/desktop, application or network - is to increase capacity, utilize resources more effectively and reduce costs. It also fits neatly with many organizations' green IT strategies, with its promise to increase utilization of existing assets and eliminate the demand for more energy-guzzling hardware resources. Virtualization is not only a hot topic but also a rapidly evolving area of the IT sector. Despite a tough macroeconomic climate, there is evidence that organizations are willing to invest in virtualization technologies, making it of great interest to incumbent vendors and those eyeing up the future market opportunity. This report is of interest to any supplier of IT products and services, whether selling direct or through a channel of resellers. This group includes virtualization vendors, hardware vendors, software vendors, open source specialists, system management providers, service providers, data centers, internet-based businesses such as Amazon offering in-cloud applications, value-added resellers and managed network service providers.
