Gundy, who worked on the project with Dr Jinjun Chen from the University of Technology Sydney, said the IT industry may be caught up in a Cloud frenzy, but there are still some major issues that need to be dealt with.

"We're dealing with very large data applications and the enterprise is a different IT application, but there is a lack of decision making tools that help people make better decisions," he said.

"...I'm very interested in smaller enterprises asking if they should move to the Cloud when no-one really knows about how secure it could be."

Security issues in the Cloud might be one reason for government bodies to be hesitant in moving, according to Gundy, who said sensitive data could be compromised if it is stored in a vulnerable Cloud model.

"This is quite new technology and there is surprisingly low knowledge about the impact of it," he said.
