4月24日，Ubuntu 8.04的服务器版本的发布，给予我们重新考虑（reconsider）“Linux产业的经营模式”的机会。这里我们要特别说明的是，“重新考虑”，这4个字是取自正式公布的Ubuntu 8.04官方文件，是一种“官方说法”。Ubuntu 8.04发布者敢于采用这个“重新考虑”说法，可见其“口气不小”。这是为什么呢？
大家知道，Ubuntu是个“另类”，它是个“集成商品包”（Integrated Commercial Products），定价却为零。它有很好的技术支持，但却绝对不强制你（事先）“接受”，也就是说，Ubuntu的技术支持，你用还是不用，随你的便。但是，Ubuntu的发布者，绝对建议你取得这类（付费的、商业的）技术支持，其中好处多多（注意：这种技术支持不论来自何方，当然，取自某些特定的厂商，效果更有保证）。这里要说明的是，Ubuntu的“技术支持”是一种常见的“商品”，可以有自己的品牌，有自己的定价、有自己的规格，有自己的......。Canonical公司是Ubuntu开发社区的主要支持者、赞助者，它所提供的多语种技术支持，毫无疑问，绝对是世界一流水平的。这里有一个非常重要的“关键点”，需要我们注意，即产品（Ubuntu 8.04）与有关它的支持服务是完全分离的，相关的“技术服务供应商”可以有各自不相同的（独立）品牌，可以属于不同的国家和地区。
根据Yankee集团“2008服务器操作系统可靠性全球调查”(by Laura DiDio)发现：有22％的被调查者在它们的服务器集合中至少有一台Ubuntu服务器在运行，这些Ubuntu服务器具有很高的可靠性，每台Ubuntu服务器的平均“年宕机时间”（“downtime”）只有1.1小时。根据国内《Ubuntu实验室》（2005.1.18~至今）以往的实际运行经验，从未发现运行中的Ubuntu服务器出现异常，影响工作。由此可见，Ubuntu服务器是可靠的、安全的（不会“寄生”病毒、木马和碟件）。
Ubuntu 8.04给予我们的商机是，独立、自主地进行Ubuntu的商业技术支持服务，包括满足客户需要的定制应用开发、知识培训、系统咨询和工程规划，等等，不会产生“厂商依赖性”（即被“不良锁定”）。当今，全球Ubuntu服务商，遍及全球各个地区(中国地区除外，不含台湾省)，已有相当规模（数百家之多）。但是，值得我们注意的是，Ubuntu作为一个“品牌商标”是不能随便使用的，需要得到Canonical的许可（注：金牌、银牌伙伴需付费，一般盟员不需付费。）。
可以预见的是，Ubuntu服务业必将在全球范围内逐渐兴起。Ubuntu是全球自由软件运动成就的集大成者，因而，我们可以说，Ubuntu服务商的先行者是很有远见的，是很值得骄傲的。
（注：很明显，Ubuntu 8.04桌面版已经呈现出Windows的优良特征（by Jason Brooks），而“谁能够赢得桌面，谁将最后赢得服务器（市场）”，这是知名IT评论家Tristan Rhodes说的话。）

UNIX的价钱不是每个企业都能接受的，综合一下个方面的因素，linux还是首选。
但从国内的形势来看，相当一部分人连windows是什么都不知道，更不用提linux了，在windows的垄断之下，linux仍然举步维艰(so):)

Or, "Why Red Hat is pursuing the wrong business strategy"
Red Hat has recently announced that they have "No plans for a traditional consumer desktop". Let me explain why I think Red Hat needs to change their business strategy.
First, a short history lesson. Before the arrival of Windows NT Server, Novell Netware claimed 90% of the market for PC based servers. However, Netware made a near fatal mistake when they did not provide a GUI interface soon enough. This comes from the same Wikipedia page linked above:
While the design of NetWare 3.x and later involved a DOS partition to load NetWare server files, this feature became a liability as new users preferred the Windows graphical interface to learning DOS commands necessary to build and control a NetWare server.
So server administrators became familiar with Windows 95 on their desktop, and they naturally preferred Windows NT 4.0 which included the same interface.
Challenged by Ubuntu
Red Hat is in a similar position to what Novell faced, in that Red Hat is facing a time when server administrators will choose to run their desktop operating system on their servers. Specifically, I believe that Ubuntu will soon become the de facto Linux desktop. This means that server administrators will become familiar with Ubuntu and develop a trust for the brand. Eventually, they may choose to migrate to an Ubuntu standard on servers and desktops.
Most people agree that the real money is in server operating systems. If Red Hat wants to keep capturing that server money, they must provide a supported, free desktop operating system as part of a loss leader strategy.
Fedora is great, but it doesn't solve this problem
Don't misunderstand me, I know that Fedora is an excellent piece of software, but it has two fundamental problems. First, most average computer users do not know that Fedora is sponsored by Red Hat. This means that the Red Hat brand is not directly benefiting from the popularity and success of Fedora.
Secondly, Red Hat does not provide any support for Fedora. This means that many business cannot seriously consider running it on their desktops. How will these business get support if a problem comes up? How will they know that their applications are certified to run on Fedora? What if they want long-term support for older versions, without having to upgrade all the time? All of these questions are being answered by the Ubuntu ecosystem.
Red Hat, let me give you a hint. (If you want more hints, I am always available for consulting). Here it is: Change the name of Fedora to "Red Hat Enterprise Desktop" and begin to sell support for it. If you are lucky, it may not be too late to capture a large percentage of the desktop operating system market.
Remove the need for CentOS
Red Hat, I will even give you one more hint for free. Why do let CentOS steal your thunder? You have already published 99.999% of CentOS (everything except the branding). You graciously publish the source code to RHEL to abide by the GPL, but then you let another brand take credit for your work. How can you fix this? Easy! Simply provide a free version of Red Hat Server that is compiled and ready to be installed. Now your users will see even more of RedHat. RedHat on their desktop, RedHat on their servers, and they can buy support for all of it if they so desire.

Yankee Group近日公布了一份报告“2007-2008全球服务器操作系统可靠性调查”，通过对来自27个国家的700多名用户进行在线调查发现，Windows Server的离线时间显著增加，而Linux的情况则有大幅好转，当然最可靠的依然是Unix。
在2006 年进行的上一次调查中，Windows Server管理员还报告说他们的离线时间要比Linux系统少很多，但现在情况变了，Windows Server 2003每年每服务器的离线时间已经接近9个小时，比上次增加了25％，而Red Hat、Novell Linux则减少了七成以上。
Yankee Group分析师Laura DiDio指出：“Windows Server 2003可靠性变差的主要原因是微软在去年夏天和秋天发布了一系列安全警告，迫使网络管理员不得不花更多的时间进行离线修复。”
Novell SUSE Linux的离线时间从大约4个小时降低到了略高于1个小时，减少73％，同时其市场份额也从13％增至17％；Red Hat Enterprise Linux离线时间减少75％，从7.1小时降至1.75小时，同时市场份额从26％增至31％；Dedian虽然超过了5个小时，但也减少了41％，份额从15％增至24％。
有趣的是，在桌面领域迅速得宠的Ubuntu第一次吸引了服务器客户，22％的受访者都表示他们至少有一台Ubuntu服务器，而离线时间仅为1.1小时。
Unix系统占了受访服务器的10％，稳定性最高，其中IBM AIX平均每年只有36分钟离线，HP-UX v1101和Sun Solaris也分别不过1.1小时和1.4小时。
