Cloud computing for Astroscience applications

Abstract

National audienceCloud computing offers virtual resources on-demand. The Infrastructure-as-a-Service (IaaS) Cloud allows to create virtual machines (VMs), virtual storage and virtual network. We present here main properties and instructions for the use of Cloud computing in the framework of the academic StratusLab Cloud. In the scientific domain of Astroscience applications, we have conducted benchmark performance tests to mesure the overhead due to virtualisation. We also performed related studies such as multi-cloud solution and cluster for Big Data
