1. e-Infrastructure & Data Services Features and implementations 1

2. Outline  Requirements  e-Infrastructure Service  Data Service  Workflow  Demo  Javadocs 2

3. e-Infrastructure & Data Service  We designed the architecture to provide a Service accessible from your application.  Modular attachable resources available to the SG thanks to the straight coupled service that allows read/write data from several e-Infrastructures. 3

4. e-Infrastructure Service  Four different kind of e-Infrastructure identified:  Local  Remote  Grid  Cloud  Possibility of defining different Policy and Quota according e-infrastructures/users availability/needs  Default and favorite e-Infrastructures selectable  Disaster recovery and (cross) file replica. 4

5. e-Infrastructure Service  If you want to copy a file on a file system you plug-in an external storage to it. 5 HFS ext4 NFS FAT

6. e-Infrastructure Service  On a SG now you are able to plug-in an e- Infrastructure. 6 Local Storage Remote Storage Grid Storage Cloud Storage

7. Data Services  Business logic related to file management totally independent from the underneath technology  All the common features associated to file provided: create, copy, delete, move and sharing.  For each features, we implemented a different Storage Interface that translates the single commands according to the technology  All data are stored in different tables in order to let users organise files on a virtual file system. 7
