How having your own slice of the cloud could be the way forward...

...move from the traditional datacentre to private clouds in their own organisations.

Microsoft, for example, has its Hyper-V Cloud initiative to help businesses speed up the deployment of private cloud by offering tools to assist the process and providing guides to integrating its own technology with those of partners such as IBM.
