Risk Aware Overbooking for Commercial Grids

Abstract. The commercial exploitation of the emerging Grid and Cloud markets needs SLAs to sell computing run times. Job traces show that users have a limited ability to estimate the resource needs of their applications. This offers the possibility to apply overbooking to negotiation, but overbooking increases the risk of SLA violations. This work presents an overbooking approach with an integrated risk assessment model. Simulations for this model, which are based on real-world job traces, show that overbooking offers significant opportunities for Grid and Cloud providers.
