Timely tech titles
They're not typical summer reading, but these books provide useful information on the job
Computerworld - We occasionally take brief note of books on technology that seem particularly useful because of the timeliness of their subjects and/or the quality of the information presented. These three titles offer comprehensive yet reasonably concise treatments of their topics.
Enterprise Service Bus, by David Chappell (O'Reilly Media Inc., 2004; 247 pages, paperback, $39.95). Chappell has managed to capture many of the virtues of both a primer and a practical handbook for working professionals in Enterprise Service Bus. The author provides a foundation-level introduction to ESB technology, including plenty of context about the nascent ESB market and the state of enterprise application integration in general. Key terms and concepts are highlighted in boxes with headings like "What Are 'Standards,' Exactly?" and "To J2EE, or .Net to Be."
The book also provides enough granular detail, practical advice and case studies to make it worth the time of IT professionals who are already familiar with ESB technology. And for all segments of the audience, Chappell and his editors have done a splendid job in presenting remarkably straightforward and useful diagrams. Readers would be hard-pressed to find a more lucid or helpful book on a technology topic.
Securing Web Services With WS-Security, by Jothy Rosenberg and David Remy (Sams Publishing, 2004; 378 pages, paperback, $39.99). Though this book opens with the assertion that Web services are a "transformational" technology for integrating information, do not fear, gentle reader. Rosenberg and Remy go beyond the hype and live up to their subtitle, "Demystifying WS-Security, WS-Policy, SAML, XML Signature, and XML Encryption."
Securing Web Services With WS-Security breezes through a few basics, but its target audience is readers who are already immersed in the technology -- Web services developers and security administrators, along with some CIOs and CTOs.

Resilient Storage Networks, by Greg Schulz (Elsevier Digital Press, 2004; 441 pages, paperback, $49.95). Even considering that it's almost 450 pages long, Resilient Storage Networks covers an extraordinary amount of ground in surprising detail. Schulz first considers the importance of data availability and then marches through descriptions and assessments
