The FAIR-EASE project as part of the European open Science Cloud aimed at delivering sustainable services for the communities. This project happened within an ecosystem evolving really fast and, marked by the launch of the EOSC EU Node as well as the consolidation of EOSC as a federation of nodes. In this new context, FAIR-EASE has positioned itself strategically by reinforcing its connections with relevant nodes, in particular those led by Data-Terra and Blue-Cloud, thereby contributing to the broader coherence and interoperability of the federation. Over the few past years, FAIR-EASE has strengthened its collaborations with several key EOSC initiatives and stakeholders. Notably, the project signed two Memorandum of Understanding (MoUs), respectively with Blue-Cloud and EGI, which represent important steps towards enhanced alignment and synergies across communities. These collaborations not only reinforce FAIR-EASE’s role within the EOSC ecosystem but also expand its capacity to deliver value for users and stakeholders. Beyond the EOSC framework, FAIR-EASE has proactively explored additional partnerships to increase its impact and foster innovation. In this regard, the project engaged with Galaxy Europe, further broadening its network of collaboration and ensuring complementarities with other research infrastructures and services of strategic relevance. Importantly, these strengthened linkages and partnerships contribute directly to the sustainability of FAIR-EASE services, ensuring that its outputs are embedded within long-lasting structures, widely adopted by user communities, and aligned with the evolving governance and operational model of EOSC. This approach guarantees that the project’s achievements will continue to generate value and impact well beyond its end. Through these concrete actions and collaborations, FAIR-EASE has consolidated its role as a bridging initiative, actively contributing to the shaping of EOSC’s federated model while fostering crossdomain and cross-community collaborations that are essential to advance open science in Europe and beyond.
