Abridging Scientific Communities Integration with A General Purpose Grid and Cloud Portal

Content:

In the framework of the Italian Grid Infrastructure, we have designed a web portal which aims at providing a powerful and easy to use gateway to distributed computing resources and cloud services provisioning. We feel that one of the key points that this kind of application must be able to address is the possibility to hide the complexity of the X.509 certificates management. In fact, while the Public Key Infrastructure is certainly one of the main aspects of the Grid environment, it is also one of the bigger obstacles that very often prevents the new users from approaching it. Through the portal users can securely run their applications without facing the complexity of the authentication infrastructure. It also interfaces with external Infrastructure-as-a-Service (IaaS) frameworks for the dynamic provisioning of computing resources. The portal architecture is based on an external authentication layer providing strong user identification by means of an accredited identity federation. The generation of a credential is handled interfacing the portal to an online CA using the OAuth protocol and saving the certificate into a MyProxy server. The portal gives full access to Grid functionality without requiring the users to have an X.509 certificate, hiding the complexity of proxy management. The portal also provides simplified access to common Grid data management operations avoiding bottlenecks for large or many concurrent file transfers. Our data management solution consists in one or more WebDAV storage devices, external to the portal, where users can easily upload their data from a standard desktop or laptop with every kind of operating system without requiring the installation of custom Grid software on the client side. The portal subsequently is in charge to asynchronously copying and registering the data over the Grid infrastructure hiding the Grid middleware complexity to the end user.
