Description

Your organization can save and thrive in the cloud with this first non-technical guide to cloud computing for business leaders

In less than a decade Google, Amazon, and Salesforce.com went from unknown ideas to powerhouse fixtures in the economic landscape; in even less time offerings such as Linkedin, Youtube, Facebook, Twitter and many others also carved out important roles; in less than five years Apple's iTunes became the largest music retailer in North America.

They all share one key strategic decision – each of these organizations chose to harness the power of cloud computing to power their drives to dominance. With roots in supercomputing and many other technical disciplines, cloud computing is ushering in an entirely new economic reality – technology-enabled enterprises built on low cost, flexible, and limitless technical infrastructures.

The Executive's Guide to Cloud Computing reveals how you can apply the power of cloud computing throughout your enterprise, giving members of the C-suite a detailed look at:

  • Why cloud computing must be a top priority on your company's IT roadmaps
  • How the drive for scale, lower costs and greater agility is making cloud computing a fiscal and technological imperative
  • The relationship between cloud computing and other relevant IT initiatives
  • The strategic implications of cloud computing for the enterprise
  • Where to begin and how to get started integrating cloud computing into your existing operations

Now you can harness cloud computing's potential for your organization. Executive's Guide to Cloud Computing shows you how.

About the Authors 267

Index 269

“A very timely and invaluable resource for CIOs, CTOs, and Enterprise Architects ... extremely relevant information that will serve readers well now and far into the future.”
Bob Flores, President & CEO Applicology Inc., Former CTO of the Central Intelligence Agency

“The authors have done a great job in explaining the cloud concepts.  They give historical and technical background to show that cloud computing is really an evolution of numerous technologies and business strategies. It is the combination of these that enables cloud and these new business strategies to happen. This makes the fuzziness of the concept come into focus. The “technical” chapters show the CIO and Technical Architect a model for building your own strategy within the business and a path from concept to deployment with governance and business models thrown in. Darn, I keep hoping for ‘the answer’. Now my questions can dig into the real value for our enterprise and a strategy for moving forward. Great book!!!”
Dave Ploch, CIO, Novus International

“‘Executive’s Guide’ is not a code-phrase for an introductory text, but a comprehensive guide for the CIO, IT decision-maker, or project leader.  The authors, two entrepreneurs and pioneers in the field, speak from substantial real-world project experience.  They introduce the topic and related technologies, highlight cloud drivers and strategy, address relationships to existing initiatives such as Service-Oriented Architectures, detail project phases in the implementation of and evolution to cloud-based enterprise architectures, and offer many reasoned insights along the way.”
Joe Weinman, Strategy and Business Development, AT&T Business Solutions

Executive’s Guide to Cloud Computing is a crystal ball into the future of business. Not a technical treatise but an insightful explanation of how cloud computing can quickly deliver real business value. This book is an instruction manual on how to win business in this ‘born on the web’ world.”
