Unibus-managed Execution of Scientific Applications on Aggregated Clouds

Our on-going project, Unibus, aims to facilitate provisioning and aggregation of multifaceted resources from resource providers and end-users’ perspectives. To achieve that, Unibus proposes (1) the Capability Model and mediators (resource drivers) to virtualize access to diverse resources, and (2) soft and successive conditioning to enable automatic and user-transparent resource provisioning. In this paper we examine the Unibus concepts and prototype in a real situation of aggregation of two commercial clouds and execution of benchmarks on aggregated resources. We also present and discuss benchmarks’ results.
