Migrating to open-source technologies

CERN’s own account of the Microsoft Alternatives project.

What it anchors

• The trigger: after twenty years on discounted “academic institution” rates, Microsoft revoked CERN’s academic status and licensing costs rose more than tenfold.
• The project’s principles of engagement: deliver the same service to every category of CERN personnel, avoid vendor lock-in to reduce risk and dependency, keep hands on the data, and address the common use cases.
• The replacement set, Keycloak for SSO among them.
