CLOUD COMPUTING ROAMING SERVICES

摘要

The present invention provides a system and method to provide Cloud roaming services. It allows Cloud services to be offered to requesters that are abstracted from the underlying Cloud provider used to fulfill those services. The present invention provides the ability for Cloud providers to be dynamically associated with currently available Cloud services for requesters. The system and method describes two scenarios - a pull and push model - to align requester required services to currently available services from Cloud providers. The requester has a profile determining a prioritized list of Cloud providers that may be used, or the primary Cloud provider may delegate services to a partner cloud. The algorithm of the present invention shows how the provider decides which requesters have access to which services-based on current utilization and forecasting. Also, from a requester perspective, location, roaming, network bandwidth and requester processing capabilities (not all- inclusive) may be sent to the provider of Cloud services to determine whether a change is needed.
