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 i Tunes 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.
