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 />
