Publication on the Pulsar Network, integrated in workflow management systems

Documentation of the design, deployment, and operationalization of the European Pulsar Network, developed within the EuroScienceGateway (ESG) project. This deliverable outlines how the Pulsar Network enables scalable, federated, and interoperable remote job execution across European Galaxy servers and compute infrastructures. This record showcases the technical architecture, automation strategies, and monitoring solutions behind the distributed execution framework, supporting reproducible workflows and efficient resource sharing. The network connects 13 Pulsar endpoints across 10 countries, integrated with six national Galaxy servers and the European Galaxy server. Deployments span public clouds, institutional HPCs, and EOSC resources, unified under a secure, open-source infrastructure stack using Terraform, Ansible, RabbitMQ, CVMFS, and SABER. The deliverable demonstrates how ESG addressed interoperability and scalability challenges through open infrastructure tooling, cross-institutional coordination, and continuous monitoring. It provides a replicable model for distributed compute resource integration and highlights Galaxy's extensibility in federated scientific computing.
