云计算产业正从传统IT
产业和互联网产业中脱胎换 骨，以全新的形态呈现在人 们眼前
云计算就是把廉价
硬件（COTS）软件化软件服务 化
服务运营化 运营规模化 的一套技术和业务模式
因此我们有必要及早定位云计算产业链、布局关键环节

A Paradigm Shift 思维转换
今天的IT竞争已经不是企 业的竞争，也不是产品的 竞争，而是进入了一场产 业链竞争 （Wintel-8/2开 放/封闭式，苹果-99.9/0.1 封闭/开放式）
云计算和下一代IDC架构和运维
Cloud Fundamentals
Infrastructure as a Service (IaaS): basic compute and storage resources On-demand servers Amazon EC2, VMWare vCloud
Platform as a Service (PaaS): cloud application infrastructure On-demand application-hosting environment E.g. Google AppEngine, , Windows Azure, Amazon
今天许多CIO，CFO仍然 在——
• 投资昂贵的设备-服务 器，路由器。磁盘 （CAPEX）;
• 等待一两年的项目实施 的周期;
• 承担项目开发和上线的 风险;
• 为维护系统，灾备而烦 恼;
• 缺乏弹性-业务需求变 化造成设备，带宽闲置 （被投资人骂翻）或不 足（被用户骂翻）。
• 把大规模、分散的 计算资源整合为可 以按须提供服务的 计算资源，提高了 IT设施的利用率， 降低了成本和用户 使用门槛
Software as a Service (SaaS): cloud applications On-demand applications E.g. GMail, Microsoft Office Web Companions
今天的IT部署方式与时俱进了吗？
• 基于运算与知识的服 务将成为社会化的服 务（utility-水电气）
