This article describes how Little Diversified Architectural Consulting, located in Charlotte NC, built a private cloud that included their high performance graphics workstations (HPGW). A private cloud differs from the public cloud providers such as Amazon Web Services or Google by the fact that the cloud computing infrastructure and resources are controlled by the individual business that deploys it. (See a brief discussion by Tom Bittman of Gartner on private cloud computing in this YouTube video.) 我们对“云计算”（Cloud Computing）和“软件作为服务”（SaaS）这些新概念已经耳熟能详，但是能不能将高性能图形工作站植入云中呢？本文介绍了位于美国北卡莱罗纳州夏洛市的Little 多元化建筑设计公司如何建立包含高性能图形工作站的“私有云”。“私有云”和“公共云”（例如Amazon Web Services or Google）不同之处在于前者云基础构架和信息资源由某个公司建立和运行。（请参见Gartner的Tom Bittman 对私有云的介绍） In general, most of the current discussion around cloud computing has been dealing with the servers (or back-end systems). Only recently have businesses begun to put their desktops and workstations into the cloud. Little’s cloud is the first AEC workstation cloud in production and is on track to reduce our workstation and laptop hardware expense by 67% ($2M) over the next 10 years. 总体而言，目前关于云计算的讨论大多数还集中在后台服务器系统上。直到最近才有公司将他们的台式机或工作站放到云上。Little 的云是AEC（建筑工程行业）领域里的首个云技术应用，其目标是在今后10年内将工作站及手提电脑硬件花费减少67%（大概2百万美元）。 Why is this solution viable now—what has changed? There are several reasons. First, the cost of network bandwidth has decreased. You can now get 10mb of metro Ethernet for the same price a T1 (1.5mb) used to cost. Also, Windows 7 and Remote Desktop Protocol (RDP) have gotten much better at moving screen images of media-rich applications. Finally, hardware costs are coming down and rack-mounted server-class workstations are within the reach of many firms. 是什么变化使得这些应用目标有望实现呢？ 有许多原因，第一，网络带宽费用降低。现在10 mb以城域太网的价格相当于之前的T1(1.5mb)的价格；另一个原因，Windows 7和远程桌面协议(RDP)在移动图形处理和多媒体动画视频方面有重大改进。最后，硬件设备费用逐渐降低使越来越多的公司能够买得起专业的机架服务器.
