What is Cloud Computing?
The definition of cloud computing
will vary depending on the intelligent mind you ask. The cloud concept is,
according to Clayton
Christensen’s theory on Disruptive Innovation, a ‘Disruptive Strategy’ in
that it replaces traditional data-centers and hosting providers by offering virtualized
computing power and remote hosting capabilities in an easier and cost-effective
manner. Essentially, what the cloud does is allow for seamless and instant
increases or decreases in scalability, whether its CPU power or storage space.
Businesses can request more CPU power from the virtual servers which provide
the cloud environment while utilizing the attractive pay-as-you-use pricing
model. Cloud service providers, like Amazon’s Web Services, do not offer just
storage capacity or CPU power, but also offer enterprise-like applications to reduce
businesses’ large initial investment in IT. So as your business is growing and
your cloud application needs more bandwidth, you can simply go online and purchase
more virtual CPU power at the click of a button. But, cloud service providers’
customers do not know whether their server capacity or CPU capability is being
shared with other clients. In fact, the CPU that just provided the computing
power for an enterprise’s application could have been the same CPU that
provided computing power for a competitors application one day prior.
Why Not Cloud Computing?
There are many main drivers for
investing in cloud computing: elimination of initial resources to create IT architectures or data centers, headcount
reduction and a reduction of equipment to provide maintenance or upgrades to servers
or data centers, and especially since Amazon
Web Services just recently slashed prices for database transactions, low cost for scalable computing power only
incurring charges as it is used. However, businesses need to see the other side
of the coin.
Recently, the public has been
made aware a government program called PRISM. PRISM is an electronic surveillance
program led by the National Security Agency. This program is suspected of
obtaining intelligence for NSA reports and essentially provides data about U.S.
citizens to the U.S. government. PRISM was first publicly leaked, in the form
of a PowerPoint, on June 6th, 2013 and included information about
several technology companies which are participants in the program. The
companies mentioned as participants in PRISM include Microsoft, Yahoo!, Google,
Facebook, Paltalk, YouTube, AOL, Skype, and Apple. In addition, it has been
made aware by the leaks that the NSA has been spying on millions of Verizon
customers in the United States by collecting telephone ‘metadata’ from all
Verizon subscribers for a period of three months; the NSA received court
approval to collect this data. If you are a Verizon customer and have made a
call in the last few months, chances are that the government knows that you
placed that call, too. However, PRISM is not limited to just call data, but also
collects e-mails, videos, photos, VoIP data, and much more.
Now, you may be asking what does
this have to do with cloud computing? The answer is nothing directly. Except
that it was just verified to the general population that the government has
been collecting (others call it spying) communication data in all sizes,
shapes, and forms. Cloud Computing is adversely affected by these news events
because cloud computing’s selling point has been the free flow of
information. Those thinking of moving to
the cloud (businesses or individuals) are thinking twice about the move since the
NSA is suspected of tapping into these goldmines of collected data and is
paying attention to the large tech giants. If a large enterprise considers
investing in the cloud, they need be aware that their information will most
likely not remain completely private forever. The recent woes of the NSA leaks combined
with the pre-existing cloud computing concerns are a powerful deterrent to
investing in the cloud. The questions
about the cloud’s data privacy and security on its shared infrastructure, the notion
that after a business invests in cloud computing they have no immediate hosting
or data center alternatives to fall back on, and the fact that it can become
costly if business transactions grow exponentially, thus reducing profitability
of the business, have turned a once-attractive technology into a potential
security and lawsuit nightmare. The leaked NSA news and the pre-existing
concerns of cloud computing are major hits to the U.S. technology marketplace’s
reputation and the future is certainly starting to look a lot less cloudy.
Privacy and data security have always been a deterrent to moving to the public cloud, and the NSA leaks added another potential hacker into the list of usual suspects (if they weren’t there already). However, privacy concerns are not the driving factor for every organization moving to the cloud - in some cases, the bottom line cost pros outweigh the privacy concern cons. If they don’t, there is always the option of a local private cloud or a hybrid cloud.
