SLA Based Service Brokering in Intercloud Environments

The fast emerging Cloud computing market over the last years resulted in a variety of heterogeneous and less interoperable Cloud infrastructures. This leads to a challenging and urgent problem for Cloud users when selecting their best fitting Cloud provider and hence it ties them to a particular provider. A new growing research paradigm, which envisions a network of interconnected and interoperable Clouds through the use of open standards, is Intercloud computing. This allows users to easily migrate their application workloads across Clouds regardless of the underlying used Cloud provider platform. A very promising future use case of Intercloud computing is Cloud services brokerage.
