Sun云计算基础设施和体系架构指南2009

白皮书第 1 版，2009 年 6 月

摘要
云计算可望提高应用程序部署速度、促进创新和降低成本，同时还增强经营敏捷性。Sun 抱持一种全面的云计算观点，因而可以支持各个层面，其中包括服务器、存储、网络和虚拟化技术，这些技术将云计算环境扩展到虚拟设备中运行的软件，而这些虚拟设备可用来在极少时间内成功汇编应用程序。本白皮书探讨云计算如何变革我们的设计、构建和提供应用程序的方式，以及企业在采纳并应用云计算技术时必须考虑的架构问题。

Abstract
Cloud computing promises to increase the velocity with which applications are deployed, increase innovation,and lower costs, all while increasing business agility. Sun takes an inclusive view of cloud computing that allows it to support every facet, including the server, storage, network, and virtualization technology that drives cloud computing environments to the software that runs in virtual appliances that can be used to assemble applications in minimal time. This white paper discusses how cloud computing transforms the way we design,build, and deliver applications, and the architectural considerations that enterprises must make when adopting and using cloud computing technology.
