SURVEYING THE CLOUD ENVIRONMENT
“Cloud computing will be a $107
billion industry by 2017; up from
$47.4 billion in 2013…The
cloud’s 23.5% CAGR is 5x faster
than that of the broader
technology market.”
IDC
“The global cloud computing
market is forecast to
grow 22% annually to US$241
billion by 2020.”
Forrester
“End-user spending on public
cloud services is likely to grow
18% in 2013 to hit a global
figure of $131 billion.”
Gartner
“The cloud market is expected to
grow to $121 billion by 2015: a
26% CAGR from $37 billion value
in 2010.”

“If you think you’ve seen this movie before, you are right. Cloud computing is
based on the time-sharing model we leveraged years ago before we could
afford our own computers. The idea is to share computing power among many
companies and people, thereby reducing the cost of that computing power to
those who leverage it. The value of time share and the core value of cloud
computing are pretty much the same, only the resources these days are much
better and more cost effective.” – David Linthicum

“There was a time when every household, town, farm or village had its
own water well. Today, shared public utilities give us access to clean
water by simply turning on the tap; cloud computing works in a similar
fashion. Just like water from the tap in your kitchen, cloud computing
services can be turned on or off quickly as needed. Like at the water
company, there is a team of dedicated professionals making sure the
service provided is safe, secure and available on a 24/7 basis. When
the tap isn't on, not only are you saving water, but you aren't paying for
resources you don't currently need.”
Vivek Kundra, CIO, US Federal Government

BUSINESS VALUE OF CLOUD OFFERINGS
16
WHY SHOULD YOU CARE?
Managing Risk
• Financial Risk – Pay as you go
• Business Risk – Hosted model, common applications
• Availability Risk – Professional management reduces downtime
Maximizing Opportunity
• Enter new business areas
• Respond to client requirements
• React to competitive activity
• Understand your business more intimately
• Security among top 5 reasons mid-size firms choose the cloud
• Most cloud data centers offer high levels of security especially when compared to mid-size data centers
• HTTPs, password protection, encryption help to keep data secure
• Audits and reviews still necessary

DELIVERY MODELS
Public CloudServices delivered on shared
resources, with appropriate security
and data isolation
Private CloudServices are delivered on dedicated
resources, generally on client
premises
Hybrid CloudConstant and/or data-sensitive
demand is met with a private
cloud that can be extended into
public cloud capacity
Community CloudPrivate cloud with smaller
number of participants
