What is the difference between a Private Cloud and Server Farm?

私有云和服务器场有什么区别。我读过一些书,老实说,他们对我来说是一样的。

有人可以给出定义和一些您可以使用的例子吗?

按照维基百科的定义

A server farm or server cluster is a collection of computer servers – usually maintained by an organization to supply server functionality far beyond the capability of a single machine. Server farms often consist of thousands of computers which require a large amount of power to run and to keep cool.

服务器场是为特定目的而创建的,例如集群计算、科学模拟、虚拟主机等,通常需要大量的计算能力。例如,facebook 在全球拥有大型服务器场,以托管其社交网络平台。

其中私有云可以定义为

The private cloud is defined as computing services offered either over the Internet or a private internal network and only to select users instead of the general public. Also called an internal or corporate cloud, private cloud computing gives businesses many of the benefits of a public cloud - including self-service, scalability and elasticity - with the additional control and customisation available from dedicated resources over a computing infrastructure hosted on-premises. In addition, private clouds deliver a higher level of security and privacy through both company firewalls and internal hosting to ensure operations and sensitive data are not accessible to third-party providers.

私有云主要供组织使用,但不需要是大型集群或大型数据中心。私有云可以是单个服务器,也可以是许多机器的集群。基本上,云的概念是通过 internet/internal 网络(如 Intranet 或 WAN)使用位于其他地方的资源。

比如一个在多个地方都有办公室的公司可以建立一个私有云供内部使用,这里私有云的服务器可能位于公司总部,其分支机构将访问私有云.

TL;DR: 服务器场通常规模较大,主要用于需要密集计算能力或数据存储的应用程序(数据场)。而私有云是为了满足特定组织的内部业务和 IT 需求,在这些组织中访问不同地理位置的资源很重要,而且与服务器场相比,它们的规模通常较小。
