前几天，Microsoft(微软)新掌门人Steve Ballmer在华盛顿大学发表了演讲，斩钉截铁、落地有声地表明微软未来产品方向，就是全部将应用云计算(Cloud Computing)，请注意的是，Ballmer这次说的是“All in”，就是粤语的“晒冷”（全部押注）的意思，这次微软似乎又迟了一步翻炒这个早已被IT界疯炒过的词-“Cloud”（云）。

自由软件(Free Software)运动领袖人物Richard Stallman曾表示，目前一些科技公司炒作云计算(cloud computing)概念实际上是“愚蠢之极”。Stallman是自由软件基金会创始人，并提出了GNU通用公共许可证理念。他在接受英国《卫 报》采访时表示，尽管谷歌(Google)、微软、亚马逊及IBM等科技公司都宣布进入云计算产业领域，并大肆宣扬云计算的好处，但实际上云计算 是这些厂商设置的一个“陷阱”，目的是引诱企业用户“上套” 后，就得使用各种专利性软件，从而导致企业用户的IT支出大幅上升。

Stallman说：“云计算概念真的很愚蠢，而这种愚蠢观念的背后实质是：它不过是一场市场营销的把戏而已。现在老有人站出来说，云计算代表着产业发 展方向，企业用户转向云计算平台已势在必行。说这些话的人其实都是在进行市场营销。”他认为，企业用户绝不应该把自己商业数据交给第三方服务商保管。

“云计算”是过去数年中刚刚出现的新概念，是指科技公司首先组建数据中心，然后向各大企业、政府部门及科研机构提供数据存储及平台测试等网络服务。 诸如社交网站、流媒体及手机互联网等业务，都可使用云计算服务。此前戴尔已推出了“云计算解决方案”项目，并对外提供数据中心设计、硬件设计和相关服务。

云端运算（英文：Cloud computing，中国大陆译作云计算，台湾译作云端运算），是一种基于互联网的计算新方式，通过互联网上异构、自治的服务为个人和企业用户提供按需即取的计算。由于资源是在互联网上，而在电 脑流程图中，网际网路常以一个云状图桉来表示，因此可以形象地类比为云端，『云端』同 时也是对底层基础设施的一种抽象概念。

云端运算的资源是动态易扩展而且虚拟化的，通过互联网提供。终端用户不需要了解“云”中基础设施的细节，不必具有相应的专业知识，也无需直接进行控制，只关注自己真正 需要什么样的资源以及如何通过网络来得到相应的服务。云计算可以认为包括以下几个层次的服务：基础设施即服务（IaaS），平台即服务（PaaS）和软件即服务（SaaS）。云计算服务通常提供通用的通过浏览器访问的在线商业应用，软件和数据可存储在数据中心。

除Stallman指责业界“炒作”云计算概念外，Oracle(甲骨文)CEO Larry Ellison也曾表示，目前IT业界几乎开口必谈“云计算”，实际上该词的真实涵义已被业界曲解，“很有意思的是，现在任何一家科技企业推 出新产品后，也不管合适不合适，都会给自己产品贴上云计算的标签。实际上，不少产品与云计算根本就沾不上边。IT产业言必称云计算，甚至超过了女性追逐时 装潮流的程度。”

在科技领域，向来是技术名词炒作的高发区，早前互联网行业都吹起WEB2.0、科技领域吹嘘纳米技术、而现在云计算，相信也是一个炒作多于实用的新名词，早前，我对其设备越来越没有归属感的DELL也开始抢注“云计算”这个名词，可惜适得其反，被网民痛骂，而草草收场。

其实所谓的云计算，目前我和我一大帮朋友的产品也轻易找到其描述的影子，作为一个实干型的IT人和IT企业，做产品应该落叶无声，管它是叫Web2.0还是Cloud，然而目前一部分互联网产品被外界称为只为投资者而存在，这就不难解释，每年都有一大堆名词遭热炒，互联网有着传媒的血统，作为一个站在众多群众面前的行业，炒作在所难免，只是别把东西简单问题复杂化，蒙了别人，也蒙了自己。名词太多，有嫌疑愚弄大众之嫌，只是看云的时候别把自己晕倒就行。现在杀毒软件被云了、电子商务被云了、ERP被云了、电子政务都被云了，你云（晕）了吗？

其实这些技术界的名词，没有真理，有点儿像我们去桂林看水晶宫，那些钟乳石，每个人看法不同，所产生的形象就不同，你能说他们错吗？我觉得我这个像云，有业界学者说，你那个规模怎么是云呢，连块棉花都比你大，但别人的不能是小云么？一定要大片云块才能算是云计算么？这样的争论，既无聊，也浪费时间，我们面对产品的时候，要善于控制自己耳朵和眼睛的接收率，或者装一个防火墙，把一些虚空的词语过滤掉。

最后，我要说的是：“杜撰一个概念比发明一项新技术来拓展市场更容易“。

附Ballmer’s speech:

Today, I spoke to a group of students and faculty at the University of Washington to discuss how cloud computing will change the way people and businesses use technology.

My goal was to challenge people to look at the cloud more broadly and understand the multidimensional nature of the cloud transformation happening today. Other companies have defined the cloud in a narrow, one-dimensional way. Although these companies provide some interesting components, Microsoft is uniquely delivering on a wide range of cloud capabilities that bring increasingly more value to our customers.

In my speech, I outlined the five dimensions that define the way people use and realize value in the cloud:

• The cloud creates opportunities and responsibilities
• The cloud  learns and helps you learn, decide and take action
• The cloud enhances your social and professional interactions
• The cloud wants smarter devices
• The cloud drives server advances that drive the cloud

This view fuels our investments across  the entire company, from datacenters to cloud platform technologies to cloud-based development tools and applications. Today, nearly every one of our products has, or is developing, features or services that support the cloud. As I said today, when it comes to the cloud, we are all in. We are all in across every product line we have and across every dimension of the cloud.

Of course, this is not news to any of you. We have been making huge investments in the cloud for the past decade. Nearly five years  ago, Ray’s “Services Disruption” memo provided the outline for what we needed to do as a company, and with the delivery of Windows Azure at the recent PDC, we have made huge strides in making this vision real.

To keep our momentum, it is critical that  every Microsoft employee works to deliver the full benefits of the cloud to our customers.

As a part of this, I request that you do the following:

• Watch the speech on demand here
• Learn more about our cloud offerings and how they relate to our overarching software plus services strategy here
• Review your commitments to ensure you are landing our vision with customers and partners.

Of course, there is more work to do. We have strong competitors. We need to be (and are) willing to change our business models to take advantage of the cloud. We must move at “cloud speed,” especially in our consumer offerings. And we need to be crystal clear about the value we provide to all our customers.

To drive our message home even further, today you will see an ad campaign in the U.S. focused on our commercial and government businesses, a new website with consolidated content and case studies, and ongoing emphasis on the cloud from me and other members of the SLT in our upcoming speeches and presentations.

We have an enormous opportunity in front of us. We have great products and services in the market today and a range of new ones on their way.

All of our products make the cloud better, and the cloud makes our products better.

Thanks,

Steve
