EU ministers, European Commission representatives, and Open Science cloud stakeholders gathered in Vienna to celebrate the official launch of the European Open Science Cloud (EOSC), the open and trusted environment for managing research data.

Mariya Gabriel, European Commissioner for Digital Economy and Society, said:

The European Open Science Cloud will allow millions of researchers to store, manage, analyse and re-use vast amounts of research data in a trusted environment across technologies, disciplines and borders. It will unlock the value of big data by providing world-class supercomputing capability, high-speed connectivity and leading-edge data and software services for science including artificial intelligence algorithms, industry and the public sector. With its governance structure in place and an online portal accessible to all, today the European Open Science Cloud becomes a reality.

Carlos Moedas, Commissioner for Research, Science and Innovation, said:

With the Open Science priority, we set out to change the way European science works. And the launch of the first Cloud portal today is a major milestone on that journey. The Cloud will give Europe a global edge in reaping the full benefits of data-driven science. Thanks to the commitment of scientists, the industry and the EU member states we have seen an idea become reality in less than three years.

The EOSC web portal is a universal entry point with the potential to help 1.7 million researchers and 70 million professionals in science, technology, humanities and social sciences to overcome geographical and institutional barriers. Through the portal, researchers 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 will enable researchers to peform their work more quickly and disseminate their research results more widely.  

Today’s launch marks a new phase of the EOSC’s development, with the first sets of services and resources, such as data archiving, educational and training materials, and a range of data processing options, already available through the portal.  The Vienna Declaration confirms the willingness of the ministers, delegates and other participants to continue working together towards realising its full potential for the benefit of European citizens, society and the economy. Efforts to make the EOSC more inclusive, covering all phases of the research cycle and all scientific communities, will go hand-in-hand with initiatives to widen its user base to the public and private sector.


The EOSC, proposed in April 2016 as part of the European Commission Communication “European Cloud Initiative - Building a competitive data and knowledge economy in Europe”,  federates existing and emerging data infrastructures and provides European researchers with world-class data infrastructures, resources and services.

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

In the months to come, the EOSC portal will be enhanced by the addition of further high-level functionalities and a wide range of scientific data and data analysis services.
