End users have said that while the technology offers to lower infrastructure costs, it is not going to stop server proliferation.

Education resource developer Curriculum Corporation IT manager Graham Williams warned organizations need to evaluate the benefits and suitability of virtualization, and develop realistic expectations.

"I think [virtualization's suitability] is horses for courses, but it offers the potential for better service and large savings," Williams said. "However, be prepared to spend money and resources in order to get returns."

Business needs to invest in research and planning before jumping into virtualization according to Craig Searle, technical team leader at information security consultant SIFT.

"It is a good answer for reducing server growth and physical structures, but my concern is that it is being seen as a cure-all," Searle said. "It needs to be seen as a solution rather than a cure."
