OK, if the cloud is so cool, why aren't you using it?

Numbers thrown up from industry surveys continue to suggest, as in the case of the one conducted by hosted services provider Rise recently, that organisations are more than willing to embrace the cloud. If this acceptance of the cloud and determination to adopt is so strong, how come more companies haven't actually taken the plunge and migrated then? Well, in the case of the Rise survey some 50 percent thought that (the old chestnut) security along with technical complexity and a lack of understanding of what the cloud is and how it works were the main barriers to migration. But can it really be as simple as that?
