5. The “non-Global” middleware CNGrid Genesis II Building and operating Grids is not trivial. Middleware installation and management requires a significant overhead w.r.t. normal system administration and almost no middleware has clear sustainability plans.

6. Using Gridsisnotstraightforward Users have to cope with complex security procedures, execution scripts, job description languages, command line based interfaces and lack of standards. This makes the learning curve very steep and keeps non IT-experts away.

7. The eResearch2020 report(http://www.eresearch2020.eu/eResearch%20Brochure%20EN.pdf) • Some barriers in the adoption of Grids: • Changes on Grids means changes on applications • Time required to adapt usual workflows • Lack of structure to support anonymous access • Download and installation of applications • Interface • Slow to get to compared to other resources • Difficult to use in the beginning • Time spent to get the application compiled and running

13. Interoperability – Does this definition apply to e-Infrastructures ? • Interoperability is a property referring to the ability of diverse systems and organizations to work together (inter-operate). The term is often used in a technical systems engineering sense, or alternatively in a broad sense, taking into account social, political, and organizational factors that impact system to system performance; • According to ISO/IEC 2382-01 (Information Technology Vocabulary, Fundamental Terms), interoperability is "The capability to communicate, execute programs, or transfer data among various functional units in a manner that requires the user to have little or no knowledge of the unique characteristics of those units".

22. Some considerations… • About 1 billion people have accounts on the existing Social Networks (many of the researchers we are targeting with e-Infrastructures are among them) • Web-based social networking accounts for more than 10-15% of the total time spent online in the whole world • Social Networks’ are by far the most used (liked) virtual environments in the world

27. Summary and conclusions • e-Infrastructures can be very beneficial platforms for many users, provided they are really «easy to use» and users are at their centre • The Catania Science Gateway framework, with support for Identity Federationschanges the way Gridinfrastructures are used, hugelywideningtheirpotentialuser base across continents and organisations, especially non-IT experts and the “citizen scientist” • The adoption of standards (JSR 286, SAGA, SAML, etc.) represents a concrete investmenttowardssustainability • The CHAIN worldwide interoperability program demonstrated that, through Science Gateways based on standards, users can really access global e-Infrastructures in a seamless and ubiquitous way independently of the underlying middleware (local, grid, cloud) • We propose to use the same approach in CHAIN-REDS to gather distributed resources from all over the region and the world and get a truly global e-Infrastructure, yet respecting local specificities and exploiting competences of all participating organisations
