中文书籍，或者国内书店里，云计算的书籍确实没有。
但是国外已经有很多了：
Cloud Computing by Michael Miller (Kindle Edition - Sep 24, 2008)
Kindle Book
Buy: $13.99
Cloud Computing: Web-Based Applications That Change the Way You
Work and Collaborate Online by Michael Miller
(Paperback - Aug 21, 2008)
Cloud Computing - The Complete Cornerstone Guide to Cloud
Computing Best Practices Concepts, Terms, and Techniques
for Successfully Planning, Implementing ... Enterprise IT Cloud
Computing Technology by Ivanka Menken
(Paperback - Nov 4, 2008)
Dot Cloud: The 21st Century Business Platform Built on Cloud
Computing by Peter Fingar (Paperback - Feb 18, 2009)
可以看到，这些书都是2008年出版的，我曾经参与过书籍提纲的讨论。个人感觉，这些书不一定对你的实际工作有直接指导作用，但它能告诉你云计算和哪些概念和技术有密切关系。
