A majority of firms across industries still do not trust the cloud, and they fear the public cloud in particular, the Information Systems Audit and Control Association reports. According to the global nonprofit information system security organization, 69 percent of the U.S participants and 68 percent of the European participants in its 2012 IT Risk/Reward Barometer believe the risks posed by public cloud services outweigh the benefits.
“What is apparent from this study is the perception of control,” said Marc Vael, international vice president of ISACA, which surveyed more than 4,500 IT professionals in 83 countries for the study. “Private cloud scores better than both public and hybrid cloud, when asked if the benefit outweighs the risk, yet take up is still relatively low.”
Cloud computing, and in particular, Internet as a service, or IAAS, has become an important piece of modern commercial IT, notes Amichai Shulman, CTO and co-founder of Imperva. While services such as Amazon EC2 allow organizations to sustain a direct correlation between their business activity volume and IT costs, however, “The same holds true for the hacking community,” he adds.
According to the ISACA survey, the drivers behind cloud computing are primarily business related, with lowering costs, increasing efficiency and introducing scalability all commonly cited drivers.
