The emergence of cloud environments has made feasible the delivery of Internet-scale services by addressing a number of challenges such as live migration, fault tolerance, and quality of service. However, current approaches do not tackle key issues related to cloud storage, which are of major importance given the amount of data produced by various sources (e.g., smart phones, cameras, social networks, etc). In this paper we discuss the challenges to providing optimized data-intensive storage services and enablers to meet them. We are building a scalable and flexible infrastructure facilitating a new data model to raise the abstraction level of storage, data mobility, computational and content-centric access to storage as well as mechanisms for cost-efficiency with provisions for QoS and security guarantees.
