But much of the industry has a legitimate alternative: If companies already own data centers, they can architect them to operate like "internal" clouds. This approach (see: http://fountnhead.blogspot.com/2008/08/creating-generic-internal-cloud.html) has all of the efficiencies and economics of using an outside cloud, but without the lock-in, standards issues, security issues of cloud computing. It's based on utility computing technologies, and is available now. These are all valid objections that enterprises will have to confront in using public clouds.
