Why cloud makes good
business sense for 2010
The cloud is an evolution in computing technology which offers companies an
opportunity to run applications beyond their own server rooms but businesses
still need to take responsibility for their data.
Although ‘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 differing
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 offer 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 offer a greener ap-proach to IT
“this technology is 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 guardtrust-ed 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 different offer-ings out there around pricing but
al-so people are going to wonder what happens if they want to move their data There are different 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 Office on the G Cloud He believes the next five years
or so will see some very interesting initiatives as officials 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 traffic, 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 different 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 different 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

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 off between low cost, instant access to server space and the level of
securi-ty on offer
At the other extreme, however, there are IT specialists who can
ad-vise on bespoke security measures as well as cloud providers who can offer 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 offer 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 different security questionnaire for every customer is a huge drain on re-sources.”

! 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 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

! 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 differ-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 invbreach-estigate varibreach-es 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

Question: How can companies encourage their IT departments to be more flexible at the
same time as offering budgetary savings?
Answer: Talk of the cloud has moved beyond rousing conferences speeches and is now a
major issue in the board room.
A couple of years ago businesses were
talking about the cloud before carrying
out limited ‘toe dipping’ pilots last year
Now, this year, is going to be one where
real life projects are going to be launched
and, in Emma Taylor’s words, the cloud is
going to start to be used widely as well as
talked about
Hence at the end of last year The Cloud
Circle was set up as an independent
members’ organisation for potential
cli-ents and experts to network and discuss
best practice
One of the big issues overhanging the
industry is that people are not sure yet
whether the cloud is as transformational
as computing experts believe it to be In
fact, when the Cloud Circle surveyed more
than 200 leading businesses at the end of
last year, one in five felt it was just hype,
a quarter believed it be ‘the real deal’ and
just over a half were yet to decide
Real experience
As more businesses take to the cloud and
take advantage of its speed, flexibility and
low cost, Taylor is convinced the benefits will become clearer for all to see
“The people who are using the cloud today tend to be using it as toe dipping, they’re seeing how they get along with using it before they do anything more major,” she says
“It’s very hard to get people to talk about projects they’re working on be-cause things are sometimes a little bit sensitive A lot of companies see their early pilots on the cloud as giving them a competitive edge and so they don’t want
to shout about it
“This year, though, I think we’re going
to get a lot more real life use of the cloud which will lead to a lot more case studies which will convince people that it really can live up to the hype.”
Little and large
So far, in Taylor’s experience, it has been companies at either end of the spectrum who have adopted cloud computing, or
at least used it for specific projects to see what they can learn
“We’re seeing mass adoption by start-ups, particularly in e-commerce, where
they can instantly see the attraction of having a large, flexible infrastructure which can expand or contract with their needs,” she says
“At the same time, large enterprises are using it, not across the entire company but on a department by department basis for specific projects
“One of the big attractions for them is that it’s so much quicker and more flex-ible It can take months within a large enterprise to requisition a development server but with the cloud you can be up and running in minutes
“Also companies that need to expand for a particular event, or which have sea-sonal peaks - such as the travel or insur-ance industries - they’re starting to ex-periment with the cloud because they want to scale up and down in response to market demand.”
Security key
Of course there are still legitimate con-cerns over regulation and security in the cloud, although Taylor believes some of these will start to be addressed as more companies, of all sizes, take to the cloud
“Security is an obvious concern for companies but we’re finding that busi-nesses are looking in to setting up private clouds for sensitive material,” she says
“Many are also looking into a public
or even hybrid offering so they can pick what information is public and which is protected better
“When you’ve got huge companies like Glaxo Smith Kline and, of course, the Gov-ernment looking into and starting to use the cloud, it should make companies re-alise that security concerns can be ad-dressed.”
Hence, with a strong push from the board room for IT to make savings wher-ever possible, the drive to move more projects into the cloud is going to build
up considerable momentum in the year ahead, Taylor believes
Companies are looking to IT to become more agile and cost effective and this is exactly what the cloud offers and deliv-ers

do your research
1 Be careful who you deal with I’d suggest that companies should work with people with a track record and when they’re looking for an operator to host their services and applications in the cloud they go for somebody that’s put a billion in to it rather than a couple of million The big operators are likely to have a better service and offer greater scale
Be prepared
2 Be sure you know what you are getting Many companies may buy a cloud service without realising that they have very little
in the way of security or a guaran-tee of service These can be
provid-ed with the right partners
plan ahead
4 For new projects, give the cloud serious consideration because it is so much simpler and quicker to set up than the formal process inside large companies of requesting a server This usually means nothing can happen on new projects for a couple of months or more

If you are looking for the next Skype, Google or eBay, then turn your attention to London-based EGS
The company recently followed these three power-houses into the Red Herring Top 100 after being named among Europe’s top private technology enterprises
EGS is one of the Cloud’s quiet success stories
But, while it lacks the glitz of some dotcom busi-nesses, the company has generated headline news by making multi-million-pound savings for large organisations
Put simply, EGS reduces its customers’ operating costs dramatically by automating back-office business processes via the Cloud
In areas such as corporate purchasing and invoice processing, EGS replaces inefficient and
expensive manual processes with Cloud-based alternatives enabling technology to do the work
in a fraction of the time and for a fraction of the cost It’s known as ‘Business Process Automation’
or BPA
EGS teams with trade bodies and partners, such
as BT and Capita, to help ambitious organisa-tions achieve multi-million pound savings In some cases, the end-to-end processing of a single ‘transaction’ can be reduced from £50-60
to just pennies As an example, one of EGS’s customers will save £2.5 million by 2012 through the automated management of hundreds
of thousands of supplier invoices using EGS’s Cloud-based tools
“We automated our first transaction in 2001
Several billion pounds worth of transactions later, we feel as though we really understand Business Process Automation,” says Peter Whent,
Chief Executive at EGS “We have accrued decades of experience in our field It’s that exper-tise that goes into our award-winning Cloud-based platform that 40,000 users across more than 120 organisations rely on to help them save millions of pounds a year.”
The urgency for businesses to make savings during the economic downturn has meant
a surge in interest in EGS For some, it’s their first foray into Cloud-based business process automation For others, it’s about overcoming stubborn obstacles that have derailed previous attempts
“With our approach, companies do more than save costs,” adds Peter Whent “They accelerate performance and create stronger relationships with suppliers and partners, while delivering
a better service to their customers Everyone benefits.”

Cloud’s scalability
saves lives for less
Many people can talk with
author-ity on how the cloud can transform
a business but very few can tell you
have they are using it to save lives
However, at the RNLI the cloud is
currently being used to run a system
that warns when a person has
fall-en off a small fishing boat or has an
emergency situation The Man Over
Board Guardian (MOB Guardian) is
being trialed in the cloud, on
Micro-soft’s Azure service, in addition to
being hosted in a conventional
da-ta centre The ultimate aim, when
it has proven resolute enough, is to
switch the data centre to act as a back
up to the cloud service and then
po-tentially switch off the data centre
service altogether
How it works
The MOB Guardian system works
through a fisherman wearing a
pen-dant that is in Bluetooth, wireless
contact with a sensor on the boat As
soon as the person goes underwater,
and contact with the sensor is lost, an alarm is raised via satellite and the stricken sailor’s position is tracked via the on board GPS (satnav) This of-fers crucial protection for lone fisher-men
“Longer fishing vessels are already monitored and have safety systems installed by law,” explains Peter Brad-ley, Operations Manager at the RNLI
“This technology is already a
prov-en life saver because it not only alerts
us to an incident, it tells the rescue crews where to find the person, so they can go straight to them.”
Bradley explains that the purpose
of mirroring the service in the cloud, before hopefully migrating it fully,
is to reduce the cost of “on premise”
servers and offer greater scale for
less money
“At the moment it’s run tradition-ally on servers in a data centre and has a capacity of 10,000 boats,” he says
“The problem is to add an extra one boat above that, we’d need to add the same infrastructure again and double up, with capacity for another 10,000 boats That’s very expensive,
so by putting this service in the cloud we’re going to be able to save a lot of money at the outset but then also we’ll be able to scale up without huge upfront costs.”
Cost is very important for the RNLI because of its charitable status The MOB Guardian service is
current-ly heavicurrent-ly subsidised and the emer-gency service needs to be able to offer
it to fishermen (and perhaps other small boats in the future) at an af-fordable price as possible
The recession has hit fishermen hard and, as Bradley surmises, “if a fisherman’s going to put their hand
in their pocket for anything at the moment, it’s going to be to mend their nets”
Hence, to save lives, it is imperative the service can be run as
efficient-ly as possible so the final cost can be brought down

is already a proven life saver”

on putting in place a series of infra-structures, in each territory, that could take 10,000 users With the cloud we can do this a bit at a time
as we need to It’s a lot more effi-cient and affordable
What if the cloud were to fail?
■
■
! We’re testing the service now
to show that it can be as ro-bust and reliable any alternative because this is obviously a huge concern for an emergency safety device such as the MOB Guardian, you can’t have it failing In fact, we think, if anything, the cloud could
be more robust because it could be set up so if one server goes down another cloud server could take over This kind of back up would be far cheaper in the cloud than locat-ing the service in more than one traditional data centre
