Security has been a showstopper for cloud computing, but private clouds are an increasingly popular method for ensuring the security of data and applications while still benefiting from cloud-computing environments. A new industry survey shows that there's lots of interest in "private" cloud" development among software developers. Half of the 500 developers questioned said they expect to deploy apps in a private cloud environment sometime over the coming year. About 30% are currently working on applications destined for a private cloud environment, while an additional 19% expect to enter development within the next 12 months.
