The sky is the limit for cloud services

If you want to under­stand the ben­e­fits of the cloud then don’t ask the ven­dors. Ask the users. And there’s no bet­ter user to ask about the cloud than food deliv­ery firm Oca­do.

Found­ed in 2002, Oca­do today makes 150,000 gro­cery deliv­er­ies a week in the UK, three-quar­ters of which are sourced from Wait­rose. It’s a firm with a very bright future. The share price has tripled in a year. A new £216-mil­lion deal with Mor­risons will help the super­mar­ket estab­lish itself online. And a recent ana­lyst report by Can­tor Fitzger­ald sug­gest­ed that Ama­zon should buy Oca­do, pri­mar­i­ly to acquire its world-lead­ing tech­nol­o­gy.

At the heart of Ocado’s oper­a­tion are cloud ser­vices pro­vid­ed by Google. For e‑mail and cal­en­dar, Ocado’s staff use Google’s busi­ness-class ver­sion of Gmail, called Google Apps. To store and share doc­u­ments, Oca­do uses Google Dri­ve. For chat­ting and col­lab­o­ra­tion there is Google+.

Paul Clarke, Ocado’s direc­tor of tech­nol­o­gy, says the cloud is under-rat­ed for these basic ser­vices. “Cost is way down on the list of why we use cloud ser­vices. It is about col­lab­o­ra­tion,” he says. “For exam­ple, if you want to share a doc­u­ment, you don’t have umpteen dif­fer­ent ver­sions fly­ing around. You have one doc­u­ment which can be edit­ed and shared. Our record is 245 peo­ple edit­ing the same doc­u­ment at the same time, which is pret­ty fun to watch.”

Google+ is some­times derid­ed as a poor rival to Face­book. Not at Oca­do. “We use it inter­nal­ly to share infor­ma­tion, for hang­outs and to cre­ate a sense of com­mu­ni­ty,” says Mr Clarke. Open con­ver­sa­tions between mul­ti­ple par­ties, com­plete with links to rel­e­vant doc­u­ments, can spring up. Old fash­ioned e‑mail con­ver­sa­tions, by com­par­i­son, are hope­less­ly crude.

There is anoth­er per­ti­nent moti­va­tion to use the cloud – the oppor­tu­ni­ty to cut car­bon emis­sions

When Oca­do is test­ing new soft­ware and ser­vices, it uses Google Com­pute Engine, which offers phe­nom­e­nal com­put­ing pow­er on demand. “One of our teams is work­ing on 3D and robot­ics,” says Mr Clarke. “They are devel­op­ing very sophis­ti­cat­ed vision sys­tems which need a lot of CPU [cen­tral pro­cess­ing unit] time. Google Com­pute Engine gives us elas­tic com­put­ing pow­er.”

Oca­do even uses Google Maps to direct deliv­ery dri­vers. Soon cus­tomers will be able to use the same cloud ser­vice to track the loca­tion of their dri­vers.
The essence of the Oca­do sto­ry is that the cloud is about more than sim­ply repli­cat­ing off-line ser­vices. It is about using the cloud to cre­ate new ser­vices, new ways of work­ing and achiev­ing step changes in per­for­mance.

There is anoth­er per­ti­nent moti­va­tion to use the cloud – the oppor­tu­ni­ty to cut car­bon emis­sions. Data cen­tres are mea­sured by their ratio of total pow­er used to pow­er used by the IT kit: a met­ric known as pow­er usage effec­tive­ness (PUE).

“Per­fect PUE is 1.0,” says Steve Salmon, prin­ci­pal advis­er of KPMG’s CIO [chief infor­ma­tion offi­cer] advi­so­ry prac­tice. “Typ­i­cal PUE is 2. The best-in-class data cen­tres see around 1.2. There are new facil­i­ties in the Arc­tic cir­cle claim­ing to have achieved a score of 1.”

By using cloud ser­vices based in data cen­tres achiev­ing this lev­el of effi­cien­cy, firms can cut their car­bon foot­print. Though Mr Salmon warns PUE is not the whole sto­ry: the con­struc­tion impact of the data cen­tre is also rel­e­vant and erect­ing a mas­sive facil­i­ty in north­ern Swe­den is not with­out its costs.

Per­haps the sin­gle biggest rea­son to use the cloud is scal­a­bil­i­ty. Hai­lo, the taxi-hail­ing app which is used every four sec­onds and is endorsed by 30,000 taxi dri­vers, relies on Ama­zon Web Ser­vices’ cloud host­ing to han­dle new busi­ness. A spokesman says: “This growth would not have been pos­si­ble with­out the scal­a­bil­i­ty of cloud com­put­ing, which enables the com­pa­ny to add capac­i­ty dur­ing busy peri­ods with a click of a mouse, and to move into new mar­kets with­out invest­ment in its own IT infra­struc­ture.”

The cost-sav­ing of cloud is hot­ly debat­ed. An oft-used anal­o­gy is rent­ing and buy­ing a car. One may be more con­ve­nient than the oth­er, but over time more expen­sive. But it’s not hard to find out­right wins for the cloud. Dig­i­tal sig­nage provider Sig­nage­live moved its entire infra­struc­ture to Rackspace’s cloud host­ing. It esti­mates a 50 per cent cost-sav­ing.

CASE STUDY

Silver lining for small businesses

Online mar­ket­ing agency atom42, which employs 24 staff in Cam­den, and counts Huff­in­g­ton Post and Match.com as clients, is a fine exam­ple.

Founder Andy Atal­la says: “We moved to Google Apps for our e‑mail, Box.net for our files and a Grad­well solu­tion for our VoIP [inter­net] phones. We also use GQueues for our task man­age­ment and Ever­note for note-tak­ing. Togeth­er, these things allow us to work at 100 per cent capac­i­ty, even if we’re out of the office, which is fan­tas­tic.

“Costs vary. At the time Google Apps was sig­nif­i­cant­ly cheap­er than the Microsoft Exchange option we were on before. Although, with Office 365, I think that has now been addressed by Microsoft. Box.net wasn’t cheap, but felt like good val­ue for the func­tion­al­i­ty. Again, though, Microsoft has had a good stab at under­cut­ting this with their new prod­uct.

“I’m a bit of a geek at times, so I actu­al­ly enjoyed the tran­si­tion. How­ev­er, if you’re a nor­mal per­son, you might want to get some­one in to help out with it all.

“There is def­i­nite­ly a larg­er strain on our band­width, so I would only rec­om­mend mak­ing such a change if you have a strong inter­net con­nec­tion. If you need a leased line put in to make this work, then you should real­ly con­sid­er the increased cost of the line as part of the over­all pack­age – this can cost around £300 per month.

“I’m def­i­nite­ly aware of the secu­ri­ty issues, but after care­ful con­sid­er­a­tion, I felt work­ing with a com­pa­ny that offered high lev­els of secu­ri­ty, as Box.net does, we were well cov­ered. After all, hav­ing your own files saved local­ly, in one place, has its own secu­ri­ty risks.”
