The European Open Science Cloud (EOSC) is a trusted digital platform for the scientific community, providing seamless access to data and interoperable services that address the whole research data cycle, from discovery and mining to storage, management, analysis and re-use across borders and scientific disciplines.

The pillars of the European Open Science Cloud initiative

Supporting the EU’s policy of Open Science, EOSC aims to give the European Union (EU) a global lead in research data management and ensure that European scientists reap the full benefits of data-driven science.

EOSC is part of the "European Cloud Initiative - Building a competitive data and knowledge economy in Europe", launched in 2016. It federates existing and emerging data infrastructures to provide European science, industry and public authorities with:

  • world-class data infrastructure to store and manage data
  • high-speed connectivity to transport data
  • powerful high performance computers to process data

To realise the ambitious objectives of EOSC, a governance structure was put in place in 2018 bringing together public funders (from Member States, Associated States and the European Commission) and the EOSC stakeholders (researchers, service providers, industry, public sector and other users). The 3-tier structure includes:

  • a Governance Board, consisting of representatives from the Member States and the European Commission who jointly decide the future of EOSC
  • an Executive Board, consisting of experts from key European research and e-infrastructures communities who advise on the EOSC’s implementation and the way forward
  • a Stakeholders Forum, giving voice to the wider community of users, service providers, industry and the public sector

Under Horizon 2020, the EU Research and Innovation programme for the 2014-2020 period, €600 million has been allocated to setting up EOSC. In the post-2020 period, EOSC will be supported by the Horizon Europe programme as the principle of open science will become the modus operandi of Horizon Europe.

EOSC Portal

The EOSC Portal is the universal access channel to EOSC services and resources. Launched in November 2018, it already covers a wide range of disciplines (e.g. medical and health, natural sciences, physics, earth sciences, arts, humanities, agriculture, and engineering). Through the portal, researchers and professionals can access open and seamless services, data, and other resources from a wide range of national, regional and institutional public research infrastructures across Europe. The portal facilitates interoperability of datasets and tools from different providers, and enables researchers to perform their work more quickly and disseminate their research results more widely.

The EOSC Portal is the result of the progressive integration and consolidation of e-infrastructure projects, with the help of Horizon 2020 funding. It started as a collective effort from the OpenAIRE, EOSC-hub, eInfraCentral and EOSCpilot projects building on the experience and technology of major pan-European e-infrastructures, universities and research infrastructures.

The EOSC Portal is currently being enhanced and maintained by the EOSC Enhance project in collaboration with the EOSC-hub and OpenAIRE projects, through the addition of further high-level functionalities and a wide range of scientific data and data analysis services. The overarching objective is to make the portal more inclusive, covering all phases of the research cycle and all scientific communities and widening its user base to the public and private sector.


Building the European data economy is part of the Digital Single Market strategy. The Commission intends to unlock the reuse potential of different types of data and facilitate its free flow across borders to achieve a European digital single market, for the benefit of the economy and society.

Aligned with the Digital Single Market strategy, EOSC is a fundamental enabler of Open Science and of the digital transformation of science. It offers the possibility to access and reuse all publically funded research data in Europe, across scientific disciplines and countries. By federating existing research data infrastructures, EOSC leverages national investments and adds value in terms of scale, interdisciplinarity and faster innovation.
