Introduction
Cloud computing is a vision of computing in the 21st Century in which most computer and
IS functionality is located on the Internet rather than on your personal computer, iPhone and
Blackberry, or corporate data center. Put simply, cloud computing is computing on the Internet.
As we see later in this essay, cloud computing is not just a technological juggernaut that inelucta-
bly is rolling over the landscape. It’s also a business product line for the largest computing corpo-

Everything is cloud computing these days and we’ve been doing it for years.”
1.0 Cloud Computing: Getting it Straight
Cloud computing is much more than just computing on the Internet-that happened already in the
1990s if not before. e reality is that cloud computing involves a number of different capabilities.
Figure 1-1 provides a graphical and more robust definition of cloud computing. In this view, cloud

platform, customers can use applications running over the Internet.

Salesforce.com which provides customer relationship management software online to thousands of
business firms around the world.
Salesforce.com is an example of Software as a Service (SaaS), a concept which is intimately linked
with cloud computing. . Other examples of SaaS provided by application servers are Google Apps
Examples of entire application development platforms on the Web include Amazon’s Elastic
Computer Cloud (EC2) which provides a virtual programming environment; Google App Engine;
Microsoft Live Mesh; and Sun network GRID. While each of these provide “platform as a service,”
they offer different services and capabilities.
In cloud computing, thousands and even hundreds of thousands of computers are located in cloud
data centers. e largest application server installation is arguably Google which has an estimated
500,000 simple PC like blade servers to perform billions of searches a day.

communications and staff required.

One of the largest cloud computing infrastructures to date is supplied by IBM’s Blue Cloud initia-
tive. By 2008 IBM announced it was building “cloud computing services” into nine IBM data
centers around the globe, each costing about $350 million each. One data center in Singapore was
specifically designed to be a cloud computing center. What’s inside a Blue Cloud data center? Not

components in a cloud data center. Air conditioning and computer power consumption are the
leading cost factors in operating a cloud data center. IBM has taken a number of innovative steps
to reduce the power consumption of its computers by 40% when compared to standard, stand alone
servers, and reduced the oor space required by 50%. Cloud computing is “green computing,” and
much more sparing of electricity than millions of PCs on corporate desktops.

Management Services Cloud computing is about more than hardware, software and physical
buildings. It’s about management of all of these elements, and in addition, other value added servic-
es that roughly fit under the rubric of “management services.” For instance, a group of managers

◆ Continuity planning
2.0 Leading Examples and Services
Cloud computing is in its infancy. It tends to leverage the resources of very large hardware manu-
facturers, but even service oriented firms like Amazon have the potential to play a large role in
cloud computing. Amazon’s example may open the door to even more cloud services being provid-
ed by very large firms with excess computing capacity on their hands.

4.0 Business Pros and Cons of Cloud Computing
Cloud computing offers business firms the potential for significant cost reductions for both soft-
ware and hardware. Software should be less costly because its cost can be spread eciently over
a large number of users. Hardware should be less expensive because large data centers can keep
their computers operating at much higher capacity levels than a single firm. e single firm is no
For this reason, large corporations have so far only off-loaded their non-critical and non-strategic
applications to the cloud. Other managers are concerned about becoming a “captive” of proprie-
tary software offered by some vendors such as IBM and HP. What happens if you want to switch
to another provider?
