<strong>Cloud</strong> <strong>Comput<strong>in</strong>g</strong> Benefits <strong>and</strong> Drawbacks 31<br />
ply sign up, <strong>in</strong> most cases, <strong>and</strong> then you have access to the cloud resources <strong>in</strong><br />
need. Those who have gone through hardware <strong>and</strong> software buys, <strong>in</strong>stallation,<br />
test<strong>in</strong>g, deployment, <strong>and</strong> the fun of deal<strong>in</strong>g with the people you need to<br />
deal with to get your stuff up <strong>and</strong> runn<strong>in</strong>g will recognize the benefit of this<br />
aspect of cloud comput<strong>in</strong>g.<br />
It’s green means that cloud comput<strong>in</strong>g is good for the environment. If<br />
you are worried about the environment, you will be happy to know that<br />
cloud comput<strong>in</strong>g is the greenest approach to comput<strong>in</strong>g out there. The ability<br />
to share comput<strong>in</strong>g resources, <strong>and</strong> thus to shut down very power-hungry<br />
data centers, reduces the need for electric power.<br />
While its “greenness” allows you to argue when sell<strong>in</strong>g cloud comput<strong>in</strong>g<br />
that those aga<strong>in</strong>st it also hate polar bears, chances are that be<strong>in</strong>g green is<br />
more of an afterthought than a major value proposition. However, while<br />
many huge corporations are call<strong>in</strong>g themselves green these days, cloud comput<strong>in</strong>g<br />
will provide them a chance to walk the walk. Most green corporations<br />
still ma<strong>in</strong>ta<strong>in</strong> humongous data centers <strong>and</strong> thous<strong>and</strong>s of services, ma<strong>in</strong>frames,<br />
storage devices, <strong>and</strong> other th<strong>in</strong>gs that have huge carbon footpr<strong>in</strong>ts.<br />
That’s not very green.<br />
Drawbacks<br />
1. Security<br />
2. Control<br />
3. Cost<br />
4. Openness<br />
5. Compliance<br />
6. Service-level agreements<br />
Security means that cloud comput<strong>in</strong>g–delivered <strong>in</strong>frastructure, because it<br />
is not under your direct control, has the potential to leave your <strong>in</strong>formation<br />
exposed <strong>in</strong> some cases. While cloud comput<strong>in</strong>g providers support encryption,<br />
user name <strong>and</strong> password–level security, <strong>and</strong> even rudimentary identity management,<br />
you still do not want to place state secrets <strong>in</strong> the clouds these days.<br />
However, most bus<strong>in</strong>ess <strong>in</strong>formation does not <strong>in</strong>clude state secrets <strong>and</strong> is perfectly<br />
f<strong>in</strong>e for cloud comput<strong>in</strong>g. Moreover, cloud comput<strong>in</strong>g is gett<strong>in</strong>g better<br />
at security as time goes on, <strong>and</strong> there is no reason to expect that <strong>in</strong>formation<br />
resid<strong>in</strong>g on cloud comput<strong>in</strong>g platforms is not as secure as, or even more secure<br />
than, on-premise systems. This is just another issue to consider.
