Private clouds are being rolled out by enterprise customers at a faster rate than previously expected as users look to cut costs.
According to research commissioned by Novell which quizzed IT directors of large enterprises 77% are already using some form of cloud computing, a level which is higher than many expected.
Most of that activity is around private clouds as firms look to extend beyond virtualisation but there are also signs that the attitude towards public platforms is also changing with 43% looking to use both external and internal application delivery methods in the future.
Security remains the main barrier to wider adoption according to the Novell research along with compliance regulations making it difficult for those that have to ensure standards around data.
"The path to public cloud computing needs to begin with the private cloud, learning to leverage the public cloud within the safety of the enterprise network," said Jim Ebzert, senior vice president and general manager of security, management and operating platforms at Novell.
The research coincided with the visit of Microsoft's CEO Steve Ballmer to London today to talk up the cloud. In a speech to partners he told them of the growth on that side of the market along with the demand that was coming through more strongly from users.
