The business driver for the private cloud is clear: Management wants to press a button and get what it needs, so that IT becomes a kind of service vend-o-matic. The transformation required to deliver on that promise seems absolutely immense to me. While commercial cloud service providers have the luxury of a single service focus, a full private cloud has an entire catalogue to account for -- with all the collaboration and governance issues that stopped SOA (service-oriented architecture) in its tracks.
The long, slow march toward greater agility and optimization of resources is basically the story of IT. It has had many names (beginning with re-engineering in the '80s), and HP has done a pretty good job of articulating the latest cloud version. And as Kedrie points out, the abundance of horsepower and bandwidth today -- not to mention the acute pain of managing increased complexity -- could let cloud computing succeed where previous grand designs failed.
But trust me, it will be incremental. People will buy bundled solutions from HP and IBM to cloud-enable this and that service inside the firewall. Advances like Cisco's OTV will make integration with service provider offerings more feasible. Meanwhile, vendors will try their usual lock-in ploys, and enterprise IT managers will protect their turf from disruptive change. It's an old story, but the creative efforts to tell it in a new way are, after all, what keep IT moving forward.
