  abstract = {This preprint outlines the development and deployment of the European Pulsar Network (EPN)—a federated, scalable architecture enabling distributed job execution across national and European Galaxy instances. Built within the Horizon Europe EuroScienceGateway project, the EPN leverages the Galaxy workflow system and the Pulsar job execution service to offload computational workloads to remote endpoints seamlessly and securely. The work introduces an Open Infrastructure (OI) framework that automates provisioning, deployment, and monitoring using Terraform, Ansible, and Jenkins. The pre-print highlights deployments across thirteen Pulsar nodes and six national Galaxy portals, illustrating how the EPN supports reproducible, FAIR-aligned data analysis while abstracting infrastructure complexity for researchers.}
