There has been a thunderstorm of growing noise
surrounding Cloud Computing in the past 24 months. Vendors, analysts,
journalists and membership groups have all rushed to cover the Cloud medium -
although everyone seems to have their own opinion and differing definition of
cloud computing. According to the most common definition, it is Internet-based
computing where shared resources, software and information are supplied to
users on demand, rather like a utility company would supply electricity, water
or gas. The term is not new; vendors such as Salesforce.com have provided Cloud
services in different guises for many years. Other players have been swift to
get on board, including Microsoft, HP, IBM, Amazon and Google, to name but a
few. Put simply, users now have the choice of a new way to consume computing
power, applications and data. No longer is it necessary to buy software on a
floppy disk or a CD. Instead, you can have immediacy of delivery through the
Internet for an application you want now. Users have been educated into this
way of working with iTunes and app stores, and they’ve come to expect a
seamless link between their locally run application and data and information
from the Internet - and at a very digestible and economic price point. Buying a
robust, polished application or game for below £1 is now taken for granted.
As an average user you are also likely to be using
cloud computing in the form of webmail, Flickr, YouTube, Facebook and a
plethora of other services; storing what you would consider private information
in the Cloud without knowing where it is in reality... or even caring.
In effect, Cloud has become a very simple and
trendy way of describing all things that occur outside the firewall whether it
be on a corporate network or on your home PC. Cloud computing is already
helping to shape the way we digest IT both at home and in the workplace. It is
simply a new ‘form factor’, a new way of delivering a solution to a customer.
We have seen new form factors disrupting and changing many market sectors
already. Think of Blockbuster Video, once the darling of the entertainment
world and now struggling to survive against the new delivery factors of Netflix
and LOVEFiLM. Tower Records, once a worldwide brand, has been put out of
business by the ability for users to now purchase music faster and cheaper via
iTunes and online music stores.
The same trends are occurring in computing. The
extraordinary speed at which Cloud computing has come to dominate the landscape
has caught many by surprise. None deny it is the Zeitgeist for 2010 when
looking back at the past year. With bold press statements such as “Cloud
computing will boost UK economy by £30bn a year” grabbing headlines, it’s no
wonder it is at the centre of so much discussion and scepticism.
With Cloud computing expected to enjoy an adoption
rate and growth of between 30 to 40 per cent per year, every year for the next
five years, vendors are rushing to launch and push their cloud offerings. From
a customer point of view, it is obviously a good thing to have more choices -
although you should be aware that in reality there is a wide range of maturity
levels amongst vendors, with some of them taking their first steps and looking
for their first few candidates for experimental purposes. The major brands,
Microsoft, Google, HP, etc are all endorsing cloud as key to their future
(Microsoft recently announced the majority of its developers have been moved to
its cloud platform), and in both business and at home it will certainly change
the way we do so many things.
Cloud computing offers substantial benefits
including efficiencies, innovation acceleration, cost savings and greater
computing power. No more 12-18 month upgrade cycles; huge IT burdens such as
system or software updates are delivered automatically with cloud computing and
both consumers, small and large organisations can now afford to get access to
cutting-edge innovative solutions. Cloud computing also brings green benefits
such as reducing carbon footprint and promoting sustainability by utilising
computing power more efficiently.
But be warned...
There will be some cloud negatives to go with all the positives. For example, with so much reliance on applications and data stored at the Internet level, what happens when you lose your Internet connection, can’t get a mobile 3G connection or the service itself isn’t available for a period? In all cases, due to circumstances outside your control, you cannot access your data, your photos or perform the action when and where you wanted.

More worryingly, we have also seen a continued
increase in threats coming from the Internet from spam, phishing (fake eBay,
bank, etc. e-mails asking you to login in order to steal your details),
viruses, spyware and scams. There was more malware on the internet in the last
18 months than the last 18 years combined. Never in the field of internet
conflict has so much impact caused by so few to so many. The attackers have
gone Cloud and are also utilising the great virtual computing power base to
their advantage. We are already starting to see malware targeting non-PC
devices. It’s in its early stages, but it is inevitable we will see more
targeting of smartphones, tablets and perhaps even Apple Macintosh as the data
that users send to the Cloud becomes more valuable - and the wider range of
applications used to access it grows at a rapid rate. With consumerisation
today’s generation of users expect to be able to access their applications from
their iPhone, iPad, BlackBerry or Android device, and they expect web-based
applications and resources to be readily available to those devices. We are
entering a time when seemingly infinite IT power and information is available
to a user on the smallest of devices, on the move and at a price affordable to
the average consumer.
Looking back, who would have expected that in 2011
you could have a 59p application on your phone which could ‘listen’ to a music
tune being played in a bar and in seconds, using the internet (accessing
massive Cloud power to do the look up and recognition analysis), present to you
the details of the track and a ‘click here’ to pay for immediate download of
the song! The chances are that Cloud will accelerate this affordable power
still further. Just imagine where we will be in ten years time!
With so much happening so fast, the pressure is on
IT experts to not only deliver more innovation but also greater security to
defend it. As devices get more powerful, the internet faster, the demand and
supply of Cloud applications will sky rocket and the power in the hands of the
user will be greater than we have ever delivered before.
Remember with great power, comes great
responsibility and your responsibility is to protect the data, your ID and the
information valuable to you. You would not go out and leave your front door
open. Therefore, don’t leave your ‘virtual’ front door open when connecting to
the internet and such powerful applications. By all means be a Cloud user, but
be safe and be secure in doing so.
