Cloud riders<br />
to be the envy <strong>of</strong> web surfers<br />
essay by Richard Constantine*<br />
A quick scan <strong>of</strong> the daily newspaper shows<br />
just how much data-driven information<br />
is being produced these days and how<br />
everyone, from decision-makers in business<br />
and government to scientists and researchers,<br />
is drawing on ever-increasing volumes <strong>of</strong><br />
data to try to solve problems.<br />
However, good decision-making requires<br />
more than just great volumes <strong>of</strong> data, no matter<br />
how accurate and up-to-date it is. Data has to<br />
be carefully mined for the right information,<br />
for the gold to be sifted from the gravel.<br />
Nowhere is data volume more a quality<br />
assurance (QA) issue than at universities,<br />
where researchers, by the very nature <strong>of</strong> their<br />
job, are confronted with vast quantities <strong>of</strong><br />
data from electronic sensors, all manner <strong>of</strong><br />
measuring tools, analytical equipment and<br />
myriad other information streams.<br />
The data that is stored and processed then<br />
forms part <strong>of</strong> a network <strong>of</strong> ‘information banks’,<br />
increasingly accessible to researchers and other<br />
users via the internet. While proximity to an<br />
information bank is no longer an issue, the<br />
ability to access and process information from<br />
any location is still a problem.<br />
The new era that is emerging is ‘cloud<br />
computing’, which allows people to access<br />
s<strong>of</strong>tware applications and their own files<br />
using any internet-connected computer,<br />
anywhere, at any time.<br />
An analogy is the provision <strong>of</strong> essential<br />
services such as electricity, water and gas. The<br />
generation and distribution <strong>of</strong> these services<br />
occurs <strong>of</strong>f-site and the consumer simply needs<br />
to ‘plug in’ to the services concerned to have<br />
them delivered down the line.<br />
All <strong>of</strong> the major IT organisations, such<br />
as IBM, Cisco Systems, Dell, Symantec,<br />
Sun Microsystems, HP and Facebook, as<br />
well as many small organisations, have<br />
already developed their own dedicated<br />
cloud computing divisions to organise the<br />
development, marketing and sales <strong>of</strong> hardware,<br />
s<strong>of</strong>tware and services in this burgeoning area.<br />
Micros<strong>of</strong>t, Google and others have developed<br />
a range <strong>of</strong> web-based applications and,<br />
importantly, web-based storage.<br />
At universities like <strong>Swinburne</strong> <strong>University</strong><br />
<strong>of</strong> <strong>Technology</strong>, students and staff are now<br />
expecting a more flexible and dynamic<br />
IT environment that will cater for them<br />
in moving between campuses, including<br />

Telecommuting, for part <strong>of</strong> the week at<br />
least, is now a more viable option for many<br />
university staff. Applications such as learning<br />
management systems, student administration<br />
systems, human resources and finance<br />
systems, to name a few, need to be available<br />
anywhere at anytime. Cloud computing or<br />
delivery via the internet is shaping as the<br />
answer to this increasing need for mobility.<br />
A number <strong>of</strong> the basic requirements for<br />
effective cloud computing are already in<br />
place, such as sufficient bandwidth with<br />
reliable, high-speed connectivity and a range<br />
<strong>of</strong> s<strong>of</strong>tware applications already available via<br />
the web.<br />
According to the Australian Bureau<br />
<strong>of</strong> Statistics, 67 per cent <strong>of</strong> Australian<br />
households have home internet access and,<br />
<strong>of</strong> these, more than 43 per cent are highspeed<br />
broadband users. It is likely that the<br />
Australian online experience would be<br />
similar to that in America, where research<br />
undertaken through the Pew Research<br />
Center’s ‘Internet & American Life’ project<br />
has shown that 69 per cent <strong>of</strong> Americans<br />
online now use cloud computing activities.<br />
While the fog is starting to lift to reveal<br />
the true form <strong>of</strong> the cloud, there are still<br />
blurred patches. The most critical element<br />
that is yet to be resolved relates to the remote<br />
storage <strong>of</strong> corporate data. It raises obvious<br />
questions about security, privacy, intellectual<br />
property and reliability <strong>of</strong> access.<br />
Who has jurisdiction over data stored<br />
in remote locations? Do we know what is<br />
happening behind the service boundary?<br />
Who is in control? What processes are in<br />
place to guarantee access to critical data or<br />
files as and when needed? It behoves us all<br />
to ensure that governance arrangements and<br />
contract terms relating to service delivery,<br />
including how the services are accessed, are<br />
fully researched and resolved.<br />
A recent detailed study <strong>of</strong> cloud computing<br />
by the <strong>University</strong> <strong>of</strong> California, Berkeley, has<br />
worked through these issues and identified a<br />
number <strong>of</strong> potential solutions, such as having<br />
multiple cloud-computing providers to ensure<br />
the availability <strong>of</strong> service and access to<br />
critical data. While the authors recognise the<br />
lack <strong>of</strong> clarity at the present time they are still<br />
optimistic for the future <strong>of</strong> cloud computing.<br />
Despite the issues to be resolved, most<br />
indications suggest that it will not be too<br />
long before we won’t just be surfing the<br />
web, we’ll be riding the cloud. ••<br />
