IT Department (CERN) is the central computing and information technology unit at the European Organization for Nuclear Research CERN. It provides core computing services, network infrastructure, data management and software development to support experiments such as Large Hadron Collider, ATLAS experiment, CMS experiment, ALICE experiment, and LHCb experiment. The department interfaces with international projects and institutions including European Grid Infrastructure, Open Science Grid, Fermilab, DESY, and KEK.

History

The department evolved from early computing activities linked to the World Wide Web project initiated by Tim Berners-Lee at CERN and the growth of distributed computing for experiments like the Large Electron–Positron Collider and the Super Proton Synchrotron. During the 1990s the unit worked closely with initiatives such as GRID computing pilots, Globus Toolkit, European Laboratory for Particle Physics collaborations, and the development of the Worldwide LHC Computing Grid. In the 2000s expansion accommodated data volumes from ATLAS experiment and CMS experiment leading to partnerships with EMBL, ESA, STFC, and national research infrastructures including CNRS, INFN, CERN openlab and IHEP. The department’s milestones intersect with projects like HTCondor, Akamai Technologies trials, OpenStack adoption, and integration with PRACE and EUDAT.

Organisation and Leadership

The department reports to CERN’s Director for Research and Computing and coordinates with unit heads similar to leaders at Fermilab, Brookhaven National Laboratory, SLAC National Accelerator Laboratory, and DESY. Its internal structure includes teams responsible for networking, data storage, cloud services, software engineering, user support, and cybersecurity, collaborating with groups at National Institute of Informatics (Japan), Rutherford Appleton Laboratory, CEA, CERN IT-PPS, and NORDUnet. Leadership has interacted with figures and bodies such as the European Commission, Council of the European Union, ITU, and representatives from member states including Switzerland, France, Germany, and Italy.

Services and Infrastructure

The department provides high-performance computing, storage, and wide-area networking, integrating services like the Worldwide LHC Computing Grid, EOS storage system, CASTOR, CVMFS, and Lustre filesystems. It operates backbone connectivity to research and education networks including GEANT, Internet2, RENATER, SURFnet, and JANET. Core services include identity and access management interoperable with EduGAIN, authentication systems influenced by OAuth and SAML standards, email and collaboration platforms comparable to Microsoft Exchange and Google Workspace deployments, and virtualization and container orchestration using Kubernetes, Docker, and OpenNebula. The department maintains monitoring and logging infrastructures leveraging tools and projects such as Prometheus, ELK Stack, Nagios, and Grafana, and supports software repositories similar to GitHub, GitLab, and CVS origins.

Research and Development

R&D spans distributed computing, data-intensive science, machine learning, and cloud-native technologies. The group has collaborated on projects with CERN openlab, QuarkNet, Horizon 2020, Marie Skłodowska-Curie Actions, FP7, and industry partners such as IBM, Google, Oracle Corporation, Intel, NVIDIA, Microsoft, Amazon Web Services, and Atos. It contributes to accelerator control system computing similar to EPICS deployments and to data analysis frameworks like ROOT and Gaudi. Machine learning work draws on platforms including TensorFlow, PyTorch, and initiatives tied to High-Luminosity LHC upgrades and upgrades planned with ATLAS experiment and CMS experiment physics programmes. The department engages with standards bodies such as W3C and participates in software preservation and reproducibility efforts in line with FAIR principles and collaborations with Zenodo and Invenio.

Security and Data Privacy

Security operations coordinate responses to incidents, vulnerability management, and identity governance, aligning with practices from ENISA, NIST, and regulatory frameworks influenced by GDPR decisions of the European Parliament and European Council. The department implements network segmentation, intrusion detection using approaches inspired by Snort and Suricata, and cryptographic systems informed by work from IETF and ISO/IEC standards. Data privacy practices are developed to meet requirements affecting datasets and collaborations with institutions including University of Geneva, ETH Zurich, Imperial College London, and University of Oxford while handling experimental metadata produced by LHCb experiment, ALICE experiment, and other detectors.

Collaboration and Outreach

The department fosters collaborations across the global research community, participating in partnerships with European Grid Infrastructure, Open Science Grid, RDA, and educational outreach with programmes such as CERN Summer Student Programme, High School Teacher Programme, Science Gateway initiatives, and collaborations with universities including University of Cambridge, Massachusetts Institute of Technology, École Polytechnique Fédérale de Lausanne, University of Manchester, Heidelberg University, Kyoto University, and Tsinghua University. It supports open-source projects, coordinates workshops with WLCG coordination, hosts training aligned with Software Carpentry and The Carpentries, and engages in public communication alongside CERN Communication Group and events like Open Days and International Conference on Computing in High Energy and Nuclear Physics.
