The HELIX project is a convergence development tool for the coordination of research-oriented electronic infrastructures in Greece. Greek researchers and members of the academic community both in Greece and abroad constitute a very large percentage compared to other countries, a community that excels internationally in many different disciplines. Its support with electronic infrastructure is becoming imperative, as this community is a part of the population with special importance for the knowledge society, which is the basic force of scientific and technological development for the country. A basic incentive for scientists to stay in their country is the existence of infrastructures equivalent to the leading states internationally. HELIX assumes this crucial role for the entire community, introducing the design, implementation and operation of three complementary electronic research infrastructures: ESIET, OpenAIRE-D, HELNET. Together and as a whole, they will form a single national ecosystem, within which research and advisory services will be provided, will support educational activities and offer relevant know-how regarding the combination of advanced telecommunications, distributed high performance computing, flexible provision of cloud computing and data processing and analysis. This ecosystem will offer various tools and infrastructures “as a service”, where part of the management capabilities will be handed over to researchers, thus facilitating innovation in new standards and frameworks providing advanced capabilities managed by researchers. With the National Research and Technology Network (EDET) member of the consortium of GEANT – pan-European academic and research telecommunications infrastructure, and PRACE – pan-European high-performance computing infrastructure HPC, and with the instigation of a broad collaboration between research and academic partners, the EYYYY infrastructure will play a leading role in the fields of network and cloud-computer infrastructure. In cooperation with other providers of electronic infrastructure across Europe, it will offer unprecedented degrees of innovation in the interconnection of local and international specialised research provisions, the movement, processing and exchange of large amounts of experimental data. The OpenAIRE-D infrastructure will take over the role of the European OpenAIRE infrastructure for Greece by offering programming frameworks for the storage, management, analysis and visualisation of scientific data, encapsulating scalable data machines and offering a multitude of relevant online services that will reduce the effort to manage available scientific data, democratising their exploitation at an interdisciplinary level. The European research infrastructures supported by the Future Internet Research and Experimentation initiative are the cornerstone for the experimental evaluation of new technologies and protocols in a real environment. The integrated infrastructure of provisions for research on the future Internet HELNET expands and integrates the FIRE distributed infrastructure in Greece into a large-scale experimental infrastructure. HELIX services will facilitate non-discriminatory access for academics and researchers to resources and tools to facilitate and improve their educational and research activities, making Greece the leading regional data-intensive research hub. Only if the completion of academic and applied research and education is activated with the international process will accelerate the country’s digital convergence with the international avant-garde. Here is the criticalness of the problem addressed by this project.
