Simulation et conception de services déportés sur grappes

Abstract : Low installation costs, scalability and code re-usability makes Clusters and Grids more and more popular computing environments. Due to this phenomenon, the Application Service Provider concept, in which costumers pay for the use of software resources, is increasingly used. The AROMA (scAlable ResOurces Manager and wAtcher) resource management system developed during this thesis studies the main problematic of service providers systems: load monitoring, high availability, hardware and software dynamicity and identity based level of service. AROMA originality both resides in its ability to deal with dynamic aspects of clusters in one hand, and in the accuracy of the state information collected on cluster nodes on the other hand. This accuracy makes it possible to deal with Quality of Service notion during the scheduling process. This work also studies cluster resources dimensioning. All the elements having an influence on Application Service Provider systems performances are taken into account: customers, software, hardware, operating systems and network components. Several simulation models have been added to the Distributed Hybrid Simulator (DHS). Those models are validated and their efficiency evaluated by comparing simulation results to both theoretical analytic results and measurements. This work originality remains in the simulation of all the elements having an influence on the global system performances. Proposed simulation models give several detail levels in order to select the appropriate precision/performance ratio.
