Massive, disruptive change is coming to IT as Software as a Service (SaaS), SOA, mashups, Web 2.0, and cloud computing truly come of age. Now, one of the world's leading IT innovators explains what it all means-coherently, thoroughly, and authoritatively.
Writing for IT executives, architects, and developers alike, world-renowned expert David S. Linthicum explains why the days of managing IT organizations as private fortresses will rapidly disappear as IT inevitably becomes a global community. He demonstrates how to run IT when critical elements of customer, product, and business data and processes extend far beyond the firewall-and how to use all that information to deliver real-time answers about everything from an individual customer's credit to the location of a specific cargo container.
Cloud Computing and SOA Convergence in Your Enterprise offers a clear-eyed assessment of the challenges associated with this new world-and offers a step-by-step program for getting there with maximum return on investment and minimum risk. Using multiple examples, Linthicum:
Reviews the powerful cost, value, and risk-related drivers behind the move to cloud computing-and explains why the shift will accelerate
Explains the technical underpinnings, supporting technologies, and best-practice methods you'll need to make the transition
Helps you objectively assess the promise of SaaS, Web 2.0, and SOA for your organization, quantify value, and make the business case
Walks you through evaluating your existing IT infrastructure and finding your most cost-effective, safest path to the "cloud"
Shows how to choose the right candidate data, services, and processes for your cloud computing initiatives
Guides you through building disruptive infrastructure and next-generation process platforms
Helps you bring effective, high-value governance to the clouds
If you're ready to begin driving real competitive advantage from cloud computing, this book is the start-to-finish roadmap you need to make it happen.

"This book cuts through all of the hype and confusion of cloud computing and brings us back to the basics of architecture. Finally, someone wrote a book that is not just about semantics but instead guides us through a methodical approach for delivering solutions in the cloud. I highly recommend this book!"

"David Linthicum has a talent for explaining how technology issues impact business decisions and strategy. Linthicum never gives you just another technical discussion about the latest tech fad. Instead, he explains the technology and the relevant business issues that both business and IT audiences need to understand before investing in cloud computing."
-Loraine Lawson
Award-winning journalist and blogger for IT Business Edge
"As cloud computing stokes the embers of the SOA hype, practitioners can count on pragmatic and opportunistic advice from Dave Linthicum. Cloud computing brings time-to-value to SOA by leveraging other people's work. In this excellent guide book, Dave shares a step-by-step plan for organizations to determine which of their services, information, and processes are good candidates to reside in, and come from, the clouds."
