Operating CERN SaaS at Scale with Operators

CERN operates over 1000 CMS websites as a SaaS on Kubernetes, managed by a small team. This talk details their experience building and using a Drupal operator to automate and scale website delivery. They discuss how they balanced reusability with CERN's specific infrastructure, best practices for developing operators, and the role of Kubernetes in isolation and multi-tenancy. The presentation also covers automated maintenance, monitoring, and lessons learned from building their first complex operator.
