Many IT
managers equate a private cloud with virtualization. What they describe is
usually virtual infrastructure, meaning that "you can treat your servers,
storage and networks as a single pool of resources that workloads can request
on demand," explains Tony Iams, an analyst at Ideas International Ltd., an
IT research firm.

许多
IT
经理把私有云等同于虚拟化。他们口中的私有云一般是指虚拟基础架构，“你可以把你服务器、存储和网络当成一个可以按需获取的单一资源池”，来自
Ideas
公司的分析员
Tony
Iams
曾经如此解释。

But virtualization
and the cloud aren't the same thing; to be considered a cloud, the architecture
must be set up to provide resource orchestration and automation on top of the
virtualization layer

.

但是虚拟化毕竟和私有云不是同一件事情。作为私有云，它在虚拟化这一层之上，它的架构还包括针对“资源的协同合作”层和“服务的自动化”层。

Orchestration
is the coordinated delivery of many types of resources, such as processors,
storage and networks, to provide an integrated provisioning process. It means
that resources can be delivered in minutes rather than days or weeks. A single
command or request causes a number of actions to occur, possibly in a specific
sequence, to coordinate the provisioning request.

“资源的协同合作”指的是协调多种资源——包括处理器、存储和网络——以提供协调的资源供给流程。它意味着几分钟资源就能够被分配，而不是几天或者几周后。一个简单的来自用户的请求，私有云将整合一系列的排列好的流程去完成它。

The whole point
of a private cloud is to allow IT managers to reduce costs and provide
so-called agile provisioning rather than just making management of the
infrastructure more convenient. A private cloud with virtualization
underpinnings turns the technology infrastructure into a pool of resources that
can be provisioned on demand with minimal manual labor.

所以，相较于如何帮助
IT
经理实现更方便的基础架构管理，私有云的重点更侧重于实现资源敏捷资源供给（

），并以此减少
IT
费用的支出。通过架构在虚拟化技术上的私有云，以及很少的运维人力资源，
IT
就可以实现一个按需供给的资源供给池。这才是私有云真正的意图所在。
