Interaction between two Clouds

I have setup the Cloud-A and I have another Cloud-B with same configuration. Say there are multiple clouds. A user is subscribed to any one of them, say Cloud-A for IaaS. As the requirements are dynamic, all the resources of Cloud-A may get exhausted. There may be another Cloud-B which can provide the services but that Cloud-A can't ask the client to go for Cloud-B.

So if it is possible to have some co-ordination between this two providers to share resources mutually, making client fully unaware of whats going on in the background....?

Please reply..

I am sorry if I'm doing mistake anywhere... Thanks in advance :)
