Balava: Federating Private and Public Clouds
Audun Nordal, Åge Kvalnes, Joseph A. Hurley, Dag Johansen · 2011
Balava is a new system for managing computations that span multiple clouds and involve data with confidentiality constraints. This paper describes the design, implementation and initial performance evaluation of Balava building-blocks. We detail the run-time developed to interconnect private and public clouds, and present a storage overlay built on top of this run-time. To support low-overhead execution of Balava computations, we are investigating alternative approaches to virtualization. We present a new hyper visor that supports light-weight virtual environments, while also preserving application binary interfaces.
