Dynamic Federations: scalable, high performance Grid/Cloud storage federations

<!--HTML-->The Dynamic Federation project aims to give tools and methods to on-the-fly federate different storage repositories whose content satisfies some basic requirements of homogeneity. The Dynafeds have been designed to work in WANs, have given so far excellent results also in LAN, and are well adapted to working with the HTTP/WebDAV protocols and derivatives, thus including a broad range of Cloud storage technologies. In this talk we will introduce the system and its recent larger deployments, and discuss the improvements and configurations that can make it work seamlessly with Cloud storage providers. Among the deployment possibilities we cite: - seamlessly using different cloud storage providers at once, thus creating a federation of personal cloud storage providers - boosting client data access performance by optimizing redirections to data that is globally replicated - easy, catalogue-free insertion/deletion of transient endpoints - seamlessly mixing cloud storage with WebDAV-enabled Grid storage - giving a WAN-distributed WebDAV access backend to services like OwnCloud/CERNBox, to enable collaboration across administrative domains/sites.
