Shaping Europe’s digital future

European Open Science Cloud (EOSC)

The European Open Science Cloud (EOSC) champions research data management to guarantee scientists’ access to data-driven science.

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

EOSC is also part of the European Data Strategy, aiming to make the EU a leader in a data-driven society. It will provide seamless access and reliable re-use of research data to European researchers, innovators, companies and citizens through a trusted and open distributed data environment and related services.

The priorities for building EOSC are set jointly by the European Commission and the EOSC Association through the co-programmed European Partnership (the EOSC Partnership) in the Strategic Research and Innovation Agenda (SRIA). Horizon Europe continues to support building EOSC on basis of the baseline that started in the Horizon 2020 programme.

The EOSC Portal provides a gateway to information and resources in EOSC. It is maintained by the EOSC Future that links together other research portals, resources and services to respond to the needs of a wide range of researchers. The service provision is strengthened by EGI-ACE, DICE, OpenAIRE Nexus, C-SCALE and Reliance.

EOSC Core Infrastructure through Public Procurement

To capitalise on the considerable research and innovation effort, fully operational enabling infrastructure for EOSC will be procured by the European Commission as part of the Horizon Europe, Research Infrastructures, Work Programme 2021-2022 provisions.

In particular, the procured EOSC infrastructure should:

  • be robust, secure, scalable, flexible and user-centric;
  • constantly be improved and upgraded following user feedback and the state-of-the-art of the underlying core technologies;
  • offer high quality of service management compliant with industrial standards and
  • provide a superior user experience, usability and ease of use for a very large number of users, with functionalities available 24/7.

The ESOC Procurement tender invites market players from industry and the research community to develop a set of innovative, modular, customisable and composable services for a wide variety of users from the research communities and beyond.

The Prior Information Notice (PIN) was published on TED (Tenders Electronic Daily).

The preliminary open market consultation was conducted through two consecutive webinars on Tuesday, 31 May 2022  and on Thursday, 9 June 2022. You can find access to the webinar recordings and the summary of the input collected on this page.

On 20 December 2022, the European Commission launched the Contract Notice to build, deploy and operate a production-grade enabling infrastructure and services for EOSC, which will provide access to a rich portfolio of FAIR (Findable, Accessible, Interoperable, Reusable) data and professional quality interoperable services.

Applicants are invited to submit their expression of interest to participate by 21 February 2023 at 17:00  (CET). All the information about the scope and conditions of this procurement is available in the TED eTendering website.  

The PIN for Independent Verification and Validation of the EOSC Platform Service Delivery is also available in the TED eTenderingwebsite. 


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.

EOSC is a fundamental enabler of open science and of the digital transformation of science. It offers the possibility to access and reuse all publicly 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.
