Abstract : Managing efficiently Cloud resources and reducing costs are major concerns for Cloud providers both economic and ecological reasons. However, It has been observed that the average usage of resources remains low, between 25-35% for the CPU. One way to improve Cloud data center resource utilization and thus reduce the total cost of ownership is to reclaim Cloud unused resources. However, reselling resources needs to meet the expectations of its customers in terms of quality of service. In this thesis the goal is to leverage Cloud unused resources for applications with SLA guarantees. To achieve that, this thesis proposes four contributions. The first one focuses on estimating real system capacity by considering SSD interferences. The second aims at estimating future use to provide availability guarantees. Then, a third contribution demonstrates the possibility of leveraging Cloud unused resources for big data without interfering with the co-located workloads. Finally, the last contribution aims at preventing malicious infrastructure owners from sabotaging the computation.
