Running a large scale matrix messenger at university medical center mainz
summary
University Medical Center Mainz deploys a production Matrix messenger for 8,700 employees (340,000 patients, 4,230 students) built from Element clients customized, running in an OpenShift cluster on IBM Cloud satellite plus Keycloak, Postgres and S3 media storage, with Argo CD GitOps and quarterly updates since 2021. A five‑year pilot from 2020 scales to hospital‑wide use, replaces shadow WhatsApp for many workflows, and enables planned case‑related chats via mobile application management; encryption is enforced end-to-end, but passphrase loss and onboarding/offboarding remain operational challenges.
