This paper proposes the development of a European Open Science Cloud (EOSC) Federation national node for Ireland (EOSC Ireland). EOSC Ireland will be a digital platform that connects researchers and research infrastructures across Ireland to the European-wide EOSC Federation. It allows researchers to share and access data, tools, and applications, making national and international collaboration easier. By engaging with EOSC Ireland, researchers can find and contribute new datasets, share analysis, and provide analytical tool and code that others can use, helping to advance scientific discovery. To achieve this, EOSC Ireland must establish essential functions such as resource catalogue and registry services, identity management, service monitoring and accounting, order management, helpdesk and service management, and application workflow management. it is crucial to onboard national HPC and data storage resources, institutional compute and storage services, research data repositories, and thematic research infrastructures to create a minimum viable product (MVP) that is useful to researchers. Furthermore, the EOSC Ireland node must be enrolled as part of the EOSC Federation, extending the scope of Open Research from Ireland to a global context. This requires ensuring the ‘EOSC Node Host’ responsible for running EOSC Ireland must be a legal entity with a sustainable funding model.
