Veteran IT chief Ian Cohen has other ideas—telling silicon. com that any company looking at moving to cloud computing purely as a way of saving money should “forget it”.

JLT’s Group CIO Ian Cohen says any company looking at cloud purely as a way of saving money should “forget it”, Cohen is speaking from experience.

As group CIO of Jardine Lloyd Thompson (JLT) he is helping the global risk management and insurance broker to make greater use of cloud-based services, such as Salesforce. com’s CRM platform.

When businesses shift to cloud services, the oft-talked-about savings won’t last, Cohen said, as any reduction in cost or overheads is quickly swallowed up by fresh demand for IT services. “If you go into cloud thinking you will save money, forget it. What invariably happens is that you create more efficiency and headroom. However, demand that previously could not be met can now be enacted and thus your activities simply increase to fill the available resources—be that time, people or infrastructure,” he told silicon.com at Salesforce’s recent CloudForce conference in London.

“People will be using your systems to do more. That’s the killer sell as to why people should be looking at cloud: the ability to flex your enterprise into a more extensible model at light speed.”

Cohen also cautioned that shifting operations to the cloud is not straightforward for any business—there will always be resistance and challenges, particularly for a heavily regulated business such as JLT.

“Its early days. We are working around some of the issues with some of the naysayers and a lot of it is around security and audit, all the usual cloud stuff,” Cohen said. “A lot of concerns are still around data location, traceability and auditability. It’s still a challenge if an auditor comes in and simply asks, ‘Where is the data? Let me see it’.

“We are a regulated business so we have to be more prudent than some other organizations but that doesn’t mean we can ignore cloud technologies and the opportunities they offer.”
