云计算是一项颠覆性技术，不仅对互联网服务，而且对整个IT行业都有深远的影响。它的出现有望简化软件、硬件和数据即服务的按需配置，实现IT解决方案部署和运营的规模经济。本期文章涉及的主题包括云计算基础设施的架构和管理、SaaS和IaaS应用程序、云计算基础设施中的服务和数据发现以及跨平台互操作性。尽管如此，仍然存在一些突出的问题，特别是与SLA，安全性和隐私以及电源效率相关的问题。其他未决问题包括所有权、数据传输瓶颈、性能不可预测性、可靠性和软件许可问题。最后，托管应用程序的商业模式必须显示出一条清晰的将云计算货币化的途径。一些公司已经建立了使用云计算基础设施的互联网消费者服务，例如搜索、社交网络、网络电子邮件和在线商务。最重要的是，云计算仍然未知的“杀手级应用”将决定我们必须开发的许多挑战和解决方案，以使这项技术在实践中发挥作用。
Cloud computing is a disruptive technology with profound implications not only for Internet services but also for the IT sector as a whole. Its emergence promises to streamline the on-demand provisioning of software, hardware, and data as a service, achieving economies of scale in IT solutions' deployment and operation. This issue's articles tackle topics including architecture and management of cloud computing infrastructures, SaaS and IaaS applications, discovery of services and data in cloud computing infrastructures, and cross-platform interoperability. Still, several outstanding issues exist, particularly related to SLAs, security and privacy, and power efficiency. Other open issues include ownership, data transfer bottlenecks, performance unpredictability, reliability, and software licensing issues. Finally, hosted applications' business models must show a clear pathway to monetizing cloud computing. Several companies have already built Internet consumer services such as search, social networking, Web email, and online commerce that use cloud computing infrastructure. Above all, cloud computing's still unknown "killer application" will determine many of the challenges and the solutions we must develop to make this technology work in practice.
