Noonan explained how the viability of cloud was mixed.
"If we were starting a small business I think it would just be a no-brainer to start picking the best of breed cloud technology and making use of it," he said. "But if you've got an organisation that's got IT that has been running for 30 to 40 years with hundreds, probably millions of dollars invested into applications ... it's a technical challenge you sort of pick up and lob over into the cloud."
He said that organisations would look through their application portfolio and pick which ones made sense to move to the cloud.
"That application doesn't really differentiate my application from someone else's: it's amenable," he explained.
On vendor lock-in, Noonan said that the vendor choice issue had been something facing IT for a long time — in terms of when companies choose particular systems, they're also locking themselves into a vendor.
However, standards to facilitate data portability also featured heavily in the discussion.
