如下是一篇对Cloud Computing的综述，着重点在硬件的方面。

Cloud Computing, the long-held dream of computing as a utility, has the potential to transform a large part of the IT industry, making software even more attractive as a service and shaping the way IT hardware is designed and purchased. Developers with innovative ideas for new Internet services no longer require the large capital outlays in hardware to deploy their service or the human expense to operate it. They need not be concerned about overprovisioning for a service whose popularity does not meet their predictions, thus wasting costly resources, or underprovisioning for one that becomes wildly popular, thus missing potential customers and revenue. Moreover, companies with large batch-oriented tasks can get results as quickly as their programs can scale, since using 1000 servers for one hour costs no more than using one server for 1000 hours. This elasticity of resources, without paying a premium for large scale, is unprecedented in the history of IT.

Cloud Computing refers to both the applications delivered as services over the Internet and the hardware and systems software in the datacenters that provide those services. The services themselves have long been referred to as Software as a Service (SaaS). The datacenter hardware and software is what we will call a Cloud. When a Cloud is made available in a pay-as-you-go manner to the general public, we call it a Public Cloudthe service being sold is Utility Computing. We use the term Private Cloud to refer to internal datacenters of a business or other organization, not made available to the general public. Thus, Cloud Computing is the sum of SaaS and Utility Computing, but does not include Private Clouds. People can be users or providers of SaaS, or users or providers of Utility Computing. We

focus on SaaS Providers (Cloud Users) and Cloud Providers, which have received less attention than SaaS Users.

From a hardware point of view, three aspects are new in Cloud Computing.

1. The illusion of infinite computing resources available on demand, thereby eliminating the need for Cloud Computing users to plan far ahead for provisioning.

2. The elimination of an up-front commitment by Cloud users, thereby allowing companies to start small and increase hardware resources only when there is an increase in their needs.

3. The ability to pay for use of computing resources on a short-term basis as needed (e.g., processors by the hour and storage by the day) and release them as needed, thereby rewarding conservation by letting machines and storage go when they are no longer useful.

We argue that the construction and operation of extremely large-scale, commodity-computer datacenters at lowcost locations was the key necessary enabler of Cloud Computing, for they uncovered the factors of 5 to 7 decrease in cost of electricity, network bandwidth, operations, software, and hardware available at these very large economies of scale. These factors, combined with statistical multiplexing to increase utilization compared a private cloud, meant

that cloud computing could offer services below the costs of a medium-sized datacenter and yet still make a good profit.

当我抬起我的头的时候，我被吃惊找有天空的一张吸引人的照片。 美丽的云在文章中扮演重要角色。 结果，一些主意对我的思想发生:云如何开始存在 ? 他们的不同颜色和形状预测什么?

我很高兴，因而英特网帮助了我解决问题。云被一些一点的水下降形成或者冰冻我们不能容易地根据我们自己眼睛见到的水晶。但是他们不是够强壮。因为如果他们遇见冷空气，他们将会折回对地球加水给下降或者冰冻水晶而且跌倒。 而且这是我们所称的雨或冰雹。

它是说云的不同颜色预测不同的天气。举例来说让我拿深黑色几个，它意谓它很快将会是下雨的。 如果你看见在太阳周围的红色的云开始上升 ,你 woule 最好不要出去。 它很快一定是 uwful 天气。

不同形状的云使我们感兴趣。他们也预测不同的天气。喜欢那一看起来像棉花一样，他们意谓你必须与一支伞。 当你离开你的家的时候。 对不起,我总是举例来说拿坏的。我认为被蒸发的面包将会让你感觉好很多。云的形状看起来像他们一样表示一个好的日子。

它很好笑或荒谬吗 ?但是证据表示他们是真实的。 当做一个说的华人去:"见到云,你将会知道天气。" 他们是天气的告示。 藉由科学的发展和科学器具的变化，人也能使用显微镜搜寻岩山天气数据。但是它有烦扰的有时找报告被犯一些错误。 它再表示人类不能控制自然。因此为了要住较安全的生活 , 它有必需的学习知道来自云的天气。
