Why cloud makes good
business sense for 2010
The cloud is an evolution in computing technology which oers companies an
opportunity to run applications beyond their own server rooms but businesses
still need to take responsibility for their data.
A
lthough ‘cloud com-
puting’ is relatively
new, the concept of
sharing computer
services has been
around for decades,
and the technologies that enable the
cloud such as virtualisation, hosting
and software as a service (SaaS) have
been available for some time.
Cloud computing refers to the de-
livery of computer services over the
Internet, as an alternative to run-
ning software on your own computer
or data centre.
Within the IT industry this topic is
complicated by too much jargon and
too many vendors with diering def-
initions to help categorise their par-

ticular implementation as cloud.
The BASDA trade group is trying
to look beyond terminology to focus
on examples of how our members are
helping real businesses transform
the way they work with this technol-
ogy.
What is ‘cloud’?
The cloud gives users the flex-
ibility of mixing and matching
the most appropriate services from
their service providers. They can be
accessed 24/7 from any Internet con-
nected PC or mobile device, making
collaboration with customers and
business partners that much easier.
Cloud providers share capacity and
support resources across a communi-
ty of users, and economies of scale re-
sult in lower cost of ownership com-
pared to traditional systems. Servic-
es are usually provided on a monthly
subscription basis, and can be easily
scaled up or down as necessary.
The IT headaches of managing the
infrastructure or keeping software
versions up to date are all handled for
you.
Cloud providers gear themselves
up for continuous operation and will

oer a comprehensive service level
agreement, with guaranteed levels of
availability in advance of the typical
in house IT set-up.

Taking responsibility
While the cloud offers sig-
nificant advantages over on-
premise it does carry potential risks
to be considered. You must carry out
due diligence to ensure steps are tak-
en to safeguard your data in terms of
availability, security, privacy as well
as legislation like the data protection
act.
Customers need to consider data
ownership, and access rights for mi-
gration if anything goes wrong at the
supplier.
It is important to realise that cloud
computing is a natural evolution of
technology, rather than some new
thing to be avoided out of hand.
Although some organisations will
embrace the cloud, others will adopt
a ‘hybrid’ approach using these serv-
ices to extend rather than replace ex-
isting systems.
The shared data centres of the
cloud can also oer a greener ap-

proach to IT.

already a proven life
saver.”

Moving applications and data be-

yond the confines of the corporate
server room and in to the cloud af-
fords massive financial savings, of-
fers previously unimaginable flexi-
bility and brings the type of applica-
tions that were once the preserve of
enterprises in to reach of more mod-
est SME budgets.
This is not to say that keeping mis-
sion critical applications in the cor-
porate server room or within a trust-
ed host’s guarded network will come
to an end. However, a new age of com-
puting is emerging where web sites
and applications can be launched in
minutes on the cloud on servers that
can be rented for weeks or months,
rather than bought up front.
Flexible scale
This is one of major advantages
which Mark Taylor, Director of Mi-
crosoft’s Developer and Platform
Group, believes is of most appeal to
business that are already using cloud
computing.
“The cloud lets you set up a pres-
ence all around the world for very
little cost compared to the huge ex-
pense of setting up servers and infra-
structure yourself in multiple data

centres,” he says.
“It’s giving SMEs global geographic
dispersion for a cost they could only
have dreamed of previously. Plus you
can scale your presence up and down
so you can add extra capacity for a
particularly busy time, such as when
year end accounts are announced,
you can increase capacity and then
take it down afterwards.
“It’s all on a pay as you consume
model and saves a fortune compared
to increasing capacity permanent-
ly in your own data centre. Although
you need to anticipate and reserve
that extra capacity in the cloud at
the moment, I believe we’re moving
to a stage where services will just be
elastic and expand as they’re needed
with people just paying for extra ca-
pacity automatically as it happens.”
Standards needed
The main hurdle which cloud oper-
ators will need to overcome, though,
Taylor believes, is opening up rival
operators’ systems so the cloud runs
along the same principles and busi-
ness models no matter who is man-
aging the hosting.
“It’s very early days but there needs

to be a lot of work done on standardi-
sation,” Taylor points out.
“There are not only dierent oer-
ings out there around pricing but al-
so people are going to wonder what
happens if they want to move their
data. There are dierent cloud serv-
ices and you can’t just pick up your
application or data and just move it
around between them.
“I think this area of standardisa-
tion and portability is a huge issue
where the service providers have to
improve and it’s also an area of op-
portunity for third parties to provide
platforms which allow the same ap-
plication to work with more than one
cloud service.”

It is not only businesses that are be-
ing attracted to the flexibility and
cost savings of cloud computing, the
Government has given the new ap-
proach a major role in its new ICT
strategy it believes will save more
than £3.2bn.
Trials of a Government Applica-
tion Store started early this month
which, it is hoped, will lead to a com-
mon platform for civil servants to ac-
cess applications that could eventu-
ally be hosted, alongside other soft-
ware tools, in the cloud. The apps
store, it is believed, could save the
Government £500m by 2020.
The proposed cloud service, or G

Cloud as it is being referred to, is ex-
pected to account for around half of
the proposed £3.2bn total savings.
The massive cost reduction should
come mainly through drastically re-
ducing the number of servers and
supporting infrastructure the Gov-
ernment requires.
Ian Osborne, Director of the Digit-
al Systems Knowledge Transfer Net-
work at Intellect UK, is one of a large
team of volunteer experts who are
advising the Cabinet Oce on the G
Cloud. He believes the next five years
or so will see some very interesting
initiatives as ocials decide what
the final service should look like.
“Ordinance Survey has already
shown how it uses cloud to service a
peak of 9m users,” he says.
“So it’s going to be a very useful tool
for departments to manage peaks in
trac, such as HMRC at the end of
January.
“A lot of sensitive data may not be
suitable for the cloud, because of se-
curity concerns and dierent depart-
ments would have to still keep their
records separate to comply with data
protection and privacy laws.

“Nevertheless, the G Cloud is a very
exciting opportunity to save the Gov-
ernment a huge amount of budget.”
For citizens, Osborne believes,
one of the biggest advantages of the
G Cloud could be allowing dierent
departments to share non-sensitive
data so paper work is reduced and
processes sped up – rather like an ex-
isting service which allows stored
passport photos to be used for driv-
ing licences.

TOP TIPS
Know what to
consider, when

Before putting a service up 
in the cloud businesses must
consider the regulatory frame-
work which their data must ad-
here to. If it needs to be stored
within geographic boundaries,
this can be accommodated, but
it needs to be stipulated and will
almost certainly increase costs
The same goes for security. 
Never assume you are being giv-
en a secure server, insist on se-
curity and service level agree-
ments (SLAs) if these are impor-
tant to you. It will push up the cost
of the service but is better than
hoping or assuming you have the
level of protection you require
Always remember that if you 
are in the public cloud you will nor-
mally not have control over whose
information is stored on the same
server. If this is a big issue, and se-
curity is a prime concern, you may
wish to discuss private cloud solu-
tions with vendors

Get safe on the cloud with
the right service mix

If there is one concern that all busi-
nesses should be fully aware of be-
fore they consider taking advantage
of the cloud, it is security.
Corporate server rooms are nor-
mally encased by a strong firewall to
ensure that only the people who are

supposed to have access to data and
let in and the remainder are locked
out. This is the mainstay of busi-
ness computing and so the sugges-
tion that the corporate server room
should be slimmed down, or even re-
placed, by a move in to cloud servers
raises serious security issues.
Pick a level
As with any computing infrastruc-
ture there are several options availa-
ble to companies and security is cen-
tral to the eventual decision an or-
ganisation opts for.
At the simplest extreme, the speed
of renting space on a server within
just a few minutes and a few clicks of
a mouse is normally the most prone
route to the cloud. It is typically tak-
en by companies that want to do de-
velopment new applications in the
cloud without the delay of commis-
sioning their own server or who want
to host public information, such as a
website. Here there is a clear trade o
between low cost, instant access to
server space and the level of securi-
ty on oer
At the other extreme, however,
there are IT specialists who can ad-

vise on bespoke security measures as
well as cloud providers who can oer
varying levels of security on servers
in the cloud but, of course, this will
increase the cost of a project.
Standard metric
As ever with the cloud, though, there
is little standardisation and so a
group of consultancies, regulators,
cloud providers and security busi-
nesses have came together at the
start of the month to work on a global
Common Assurance Metric (CAM).
This resulting system of security
scores is hoping to get around the
problem that most measures of secu-
rity protection are normally linked
to particular bespoke products and
so can make rating applications time
consuming and oer a result which
cannot be easily compared to other
products.
The group of experts is expected to
have the outline of the CAM ready by
the end of the year. When it is com-
plete it will allow security vendors
and cloud operators to have their
services rated so potential clients
can make informed decisions based
on an industry-wide standard.

According to Giles Hogben, Net-
works Security Policy Expert at the
EU’s information security agency,
ENISA, the global standard is a wel-
come move.
“The CAM work is essential,” he
says. The number one barrier to adop-
tion of cloud computing is assurance
– “how can I know if it’s safe to trust
the cloud provider?” This is a prob-
lem for providers too - answering a
dierent security questionnaire for
every customer is a huge drain on re-
sources.”

adoption of cloud

FACTS
94% of more than 10 00 security pro-
fessional recently told trade show InfoSe-
curity Europe that the one reason they or
their clients were not committing to the
cloud are concerns over levels of security
3 in 4 companies also revealed in a 
sur vey run by InfoSecurity Europe that
they intend to spend more budget in the
year ahead securing cloud services as
well as applications run through a Soft-
ware as a Service model

The NHS certainly believes cloud 
services can be secured. It has just
signed a five year cloud security deal
thought to be worth around £6m
Hence the latest advice given out at 
the recent Westminster eForum on the
cloud by the Information Security Profes-
sionals Organisation is to switch from la-
belling the cloud as not safe to making it
secure because the technology is being
adopted regardless of individual mem-
ber’s concerns
Can bu siness tru st the cloud?
!
The benefits are numerous
but arguably the biggest bar-
rier to adoption is security con-
cerns, so unfortunately, it would
seem that businesses don’t trust
the cloud.
There’s no reason for this if or-
ganisations have the correct secu-
rity solutions in place. And by secu-
rity solutions, I don’t mean ‘lock-
down’; I mean a security solution
which is flexible and tailored to
the specific demands of each busi-
ness, something which gives or-
ganisations the confidence to em-
brace the benefits of cloud-based

solutions.
The key issue is not security of
the cloud itself but ensuring the
exit and entry points between your
business and cloud-based services
are watertight.
Are security and regulation 
driving private clouds?
!
Without a doubt, I would say
that data security and regula-
tion is a key focus for private
cloud providers.
Perhaps what has made the
cloud security debate rage so
fiercely is the fact that potential
issues or breaches could be poten-
tially catastrophic. Plus relying on
highly centralised cloud solutions,
with data being stored in a dier-
ent country, creates significant
challenges for business as they
struggle to comply with additional
legislation.
Local solutions can help busi-
nesses overcome these challenges,
along with private clouds.
What comeback does a busi-
ness have if there is a security
breach in the cloud?

!
The protection businesses
can call upon in case of a
breach is all down to the contracts
it has in place with their cloud pro-
vider.
The service level agreements, the
course of action they will take, the
level of information about breach-
es and ability to investigate varies
greatly on the provider.
I would strongly encourage busi-
nesses to obtain the service lev-
el agreements they require before
committing to a cloud provider.
