                      Strategic Research Agenda 6.<br><br>A Federated Computing
                      Infrastructure/Framework is the concrete implementation and
                      operation term for a suite of technologies and
                      functionalities aiming at the coordinated management and
                      interoperability of data, resources, and processes across
                      different systems, locations, and organizational boundaries.
                      The framework envisions a decentralized architecture for
                      creating and managing an interconnected network of resources
                      where each participant (which could be a data centre, a
                      system, an application, or any other device) may be used to
                      achieve the intended result, breaking away from the
                      traditional monolithic approach. This framework allows
                      organizations to collaborate and share resources without
                      fully giving up local control and thus to maintain a
                      selectable level of autonomy. Federated Computing
                      Infrastructures are designed from the beginning to be
                      modular and adaptable, allowing resource-providing
                      organizations to choose their level of involvement in the
                      federation to ensure seamless integration with their
                      existing platforms and regulatory requirements. The broader
                      applicability of Federated Computing Infrastructure is
                      pivotal for utilizing distributed data assets among and
                      across organizations and within an organization. Federated
                      Computing Infrastructures enable organizations and users to
                      leverage distributed assets and drive innovation,
                      collaboration, and value creation.<br><br>The key
                      characteristics of a Federated Computing
                      Infrastructure/Framework
                      are:<ol><li><b>Decentralization</b>: Each organisation
                      participating in the Federated Computing Infrastructure
                      makes available its resources while retaining a selectable
                      level of autonomy and
                      independence,</li><li><b>Interoperability</b>: The Federated
                      Computing Infrastructure is designed to enable the
                      interaction among different systems built on different
                      technologies, protocols, or
                      standards.</li><li><b>Openness</b>: The Federated Computing
                      Infrastructure is open and accessible by any entitled
                      organisation aiming at using its resources, provided that
                      the authorization and data security criteria are
                      met.</li><li><b>Scalability</b>: The Federated Computing
                      Infrastructure enables seamless scaling because new
                      organizations, devices and resource-providing institutions
                      can be added to the federation without interfering with the
                      existing Infrastructure. </li><li><b>Data security and
                      sovereignty</b>: The concerns of data protection, data
                      security and privacy-preserving computation are ubiquitous,
                      and the Federated Computing Infrastructures provide tools
                      and safeguards</li><li><b>Fault tolerance, redundancy and
                      resiliency</b>: Because resources are distributed across
                      systems, locations, and organizational, the Federated
                      Computing Infrastructure offers natural redundancy,
                      enhancing the overall resiliency of the architecture. When
                      one unit experiences a fault or is withdrawn from the pool
                      of available resources, the problem is generally isolated to
                      that particular unit, minimizing the impact on the entire
                      system.</li></ol>The concept of Federated Computing
                      Infrastructure/Framework provides a strategic framework that
                      allows for the coordinated management and interoperability
                      of data, resources, and processes. It’s particularly
                      valuable in the EU environment for the exploitation of the
                      computational resources deployed e.g. within the EuroHPC JU
                      programs and initiatives, the Worldwide LHC Computing Grid
                      (WLCG) and the likes, where it is of paramount importance
                      for systems to be autonomous yet able to share compute
                      power, data and resources effectively. However, the benefits
                      come with their own set of challenges, such as increased
                      complexity, inter-system security concerns and potential
                      governance conflicts. Nonetheless, when designed and managed
                      within a proper governance, adequate operational and policy
                      guidelines, Federated Computing Infrastructures provide a
                      powerful way to build flexible, scalable, and collaborative
                      systems.<br><br>This white paper explores the conceptual
                      models of Federated Computing Infrastructure/Framework, the
                      current deployments, the challenges facing the widespread
                      exploitation of the Federated Computing Infrastructure and
                      proposes a number of key $R\&I$ recommendations for a smooth
                      and effective exploitation of the current and future
                      deployments. Looking forward, the white paper outlines a
                      Post Exascale Vision providing guidelines for designing
                      future-proof Federated Computing Infrastructures.},
