The EOSC Future project is the major implementation project building the European Open Science Cloud (EOSC). Putting together expertise from major European research infrastructures (computing, network, storage, data, tools) the project is working on operationalising the EOSC. It also builds on previous EC-funded projects that developed core components of this platform. The architecture connects and integrates existing and new technological elements. It brings in relevant data content and tools to investigate and analyse. This is carried out by a large consortium of over 90 European partners, in collaboration with researchers and important European stakeholders.
