What is Intercloud?
Intercloud cloud computing concept that proposes that each single cloud does not have infinite physical resources or ubiquitous geographic footprint. If a cloud saturates the computational and storage resources of its infrastructure, or is requested to use resources in a geography where it has no footprint, it would still be able satisfy such requests for service allocations sent from its clients.The Intercloud scenario would address such situations where each cloud would use the computational, storage, or any kind of resource of the infrastructures of other clouds.
This is analogous to the way the Internet works, in that a service provider to which an endpoint is attached, will access or deliver traffic from/to source/destination addresses outside of its service area by using Internet routing protocols with other service providers with whom it has a pre-arranged exchange or peering relationship. It is also analogous to the way mobile operators implement roaming and inter-carrier interoperability.
