Abstract : The emergence of Cloud computing brings forward many challenges that may limit the adoption rate of the Cloud paradigm. As data volumes processed by Cloud applications increase exponentially, designing efficient and secure solutions for data management emerges as a crucial requirement. The goal of this thesis is to enhance a distributed data-management system with self-management capabilities, so that it can meet the requirements of the Cloud storage services in terms of scalability, data availability, reliability and security. Furthermore, we aim at building a Cloud data service both compatible with state-of-the-art Cloud interfaces and able to deliver high-throughput data storage. To meet these goals, we proposed generic self-awareness, self-protection and self-configuration components targeted at distributed data-management systems. We validated them on top of BlobSeer, a large-scale data-management system designed to optimize highly-concurrent data accesses. Next, we devised and implemented a BlobSeer-based file system optimized to efficiently serve as a storage backend for Cloud services. We then integrated it within a real-world Cloud environment, the Nimbus platform. The benefits and drawbacks of using Cloud storage for real-life applications have been emphasized in evaluations that involved data-intensive MapReduce applications and tightly-coupled, high-performance computing applications.
