The above panelists said that IT needs a paridigm shift to work in the cloud. It needs to be a broker of services rather than builder.
The industry must also change. If a CIO can pick and chose cloud services, the IT department needs some way of measuring end-to-end service delivery. You may get your compute from Amazon, your network from BT and your storage from an HP cloud. Who is responsible when your cloud-based enterprise system fails?
In traditional IT, IT departments provide complex SLAs acrosss mutliple suppliers. But these are one-to-one relationships, where the user manages individual supplier SLAs. The cloud needs what HP describes as a consume-subscribe model, where suppliers can publish vital information about the services they offer and SLAs in a common location or enable this information to be federated and brokered, allowing buyers to build an end-to-end service using service coponents in the cloud.
