01 Virtual resources allocation for workflow-based applications distribution on a cloud infrastructure
Cloud computing infrastructures are providing resources on demand for tackling the needs of large-scale distributed
applications. Determining the amount of resources to allocate for a given computation is a difficult problem though.
This paper introduces and compares four automated resource allocation strategies relying on the expertise that can be
captured in workflow-based applications. The evaluation of these strategies was carried out on the Aladdin/Grid’5000
test bed using a real application from the area of medical image analysis. Experimental results show that optimized
allocation can help finding a tradeoff between amount of resources consumed and applications make span.
02 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
