The <strong>SIENA</strong> <strong>European</strong> <strong>Roadmap</strong> on Grid and Cloud Standards for e-Science and Beyond 8 e-Infrastructure Requirements Different communities will have different needs from the future <strong>European</strong> e-infrastructure. Our focus is to identify the core common requirements relating to the provision of e-infrastructure that the communities have rather than the specific functionality used by particular communities. »» Single Sign-On: Inter-domain access to services from different communities demands secure, portable, electronic identity that can be used across different service providers. The federated identity providers that are being established in Europe present one possible solution to this requirement. »» Security: Supporting secure and dynamic resource (including data, knowledge, and services) sharing and collaborations across institutional and national boundaries is an essential part of achieving the vision of an e-infrastructure. Robust electronic authentication capable of reliably identifying remote users (human beings or software components) with a certain level of assurance in authentication strength is an important pre-requisite to facilitate effective user authorisation and fine-grained access control to distributed services 14 . »» Group Management: Managing individual access to resources across Europe is not feasible considering the number of users and resources. Using group based access control, such as the virtual organisation models used in grids, the project model used in HPC and the attributes model used in federated identities, provides a more scalable access control model. »» Persistent Data Identifiers: The ability to uniquely identify a data set, and from that data set identify its ownership, access rights, privacy attributes provenance, life-time, stored locations, etc. is vital for systematic reuse of data across communities. »» User Support: Support is needed for all types of users (end-users, system administrators, developers, etc.) across the complete life-cycle of e-infrastructure adoption. This includes training on the deployed technologies, consultancy on their use and problem solving when something goes wrong. This is needed both for the core infrastructure and any domain specific software that is deployed on top of it. »» Virtualisation: Communities need to deploy their own services, potentially co-located with particular data sets, on sites across Europe on demand. Such activity can then be decoupled from the deployment activities of other communities. »» High Throughput Data Analysis: Such communities need to be able to move large datasets to where the computing resources are available, and to move the results from such analysis to where long-term storage capacity is available. In addition to the previous requirements this requires a high-performance pan-<strong>European</strong> networking infrastructure closely coupled to data-centres with large computing and storage capabilities as supported through the EGI-InSPIRE project. »» High Performance Computing: Peta-scale computing resources are essential for the small proportion of researchers solving science’s most demanding problem through projects such as PRACE. Efficient access to the small number of peta-scale machines in Europe is facilitated through high-performance networking links. 14] See E-infrastructure Security: Levels of Assurance Final Report: www.jisc.ac.uk/media/documents/programmes/einfrastructure/finalreport.pdf
e-Infrastructure Technology e -infrastructure in Europe has reached a production status over the last decade by driving innovation in middleware and networking technology. This innovation needs to continue over the next decade in areas such as: » » Virtualisation: High-quality hypervisors that underpin virtualisation in modern datacentres are becoming commonplace. Commercial solutions provide integration with data centre operations. Open-source solutions, such as the OpenNebula environment, are being used as powerful tools for innovation and interoperability in the research community, and as platforms to implement new standards in cloud computing.” » » Networking: Driven by the worldwide growth of the Internet commercial networking solutions are available for deployment to support public service activities. A focus on on-demand cross-domain provisioning of high-speed data transfer links (light paths) with defined service level agreements is an area which needs continuing investment. » » Software: The software platforms and services necessary to federate the virtualised resources to provide seamless access and to run within the virtualised environments continue to need investment. Increasingly, investment needs to take place through acquisition of commercially provided software solutions where they exist and allowing the research community to innovate through open-source software in areas where they can add unique value beyond the scope of commercial solutions.
