基于物联网的行业创新—手机支付 绿色农业、工业监控、气象水文监测、路灯控制、环境监测、智能交通等等。 基于物联网的行业创新—公共行业监测监控 那么什么是智慧城市？美国的IBM公司是“智慧城市”的倡导者，他们对“智慧城市”给出了这样定义，简单的理解就是在城市的发展过程中， 利用信息通信技术来对整个城市进行感知，分析，整合，从而创造一个更加美好的城市，让市民更加幸福的生活和工作。 智慧城市的建设具有重要的意义：一方面可以推动政府的社会管理能力和公共服务水平；另一方面能够在城市建设、转型、发展中起到重要的作用。 * * * * 从Google Trends 获取的信息我们可以看到，云计算在 2007年末才被该系统统计，并且一直处于上升趋势。 * * Jeff Bezos’ quote: /8301-13953_3-9977100-80.html?tag=mncol Kevin Marks quote: /8301-13953_3-9938949-80.html?tag=mncol video interview * * Massive Scale. Cloud implementations, regardless of the deployment model, tend to be as large as possible in order to take advantage of economies of scale. Large cloud deployments can often be located next to cheap power and real estate to lower costs. They often take advantage of bulk commodity hardware purchases and streamlined datacenter technologies (e.g., contain based data centers). To improve effectiveness, large cloud deployments may be located near high speed Internet hubs. Virtualization. Virtualization is a critical element of most cloud implementations and is used to provide the essential cloud characteristics of location independent resource pooling and rapid elasticity. Virtualization, when used in the cloud paradigm, enables data centers to increase their server utilization from a typical 10% to an ideal 80% thereby producing significant cost savings. This said, other techniques (such as software sandboxing in a PaaS model) can provide similar benefits although they are less used. Non-stop computing. Cloud implementation (especially SaaS and PaaS) often enable a characteristic of non-stop computing. This means that cloud applications can take advantage of the abstraction of the cloud distributed software layer from the hardware to enable an application to remain active at all times even through upgrades. In this model there are no scheduled maintenance downtimes for applications. Free Software. The massive scale of many clouds combined with the need for many software licenses encourages
