BonFIRE will support experiments exploring the interactions between novel service and network infrastructures. Three initial scenarios have been defined to highlight the general classes of experiment that can be supported by the facility. The scenarios include Extended cloud scenario: the extension of current cloud offerings towards a federated facility with heterogeneous virtualized resources and best-effort Internet interconnectivity. Cloud with emulated network implications: a controlled network environment by providing an experimental network emulation platform to service developers, where topology configuration and resource usage is under full control of the experimental researcher. Extended cloud with complex physical network implications: investigates federation mechanisms for an experimental cloud system that interconnects individual BonFIRE sites with Federica, Open Cirrus and Panlab.
