Cut the SaaS: How I Saved Thousands With Kubernetes & Open Source
summary
Replaces multiple SaaS with a self‑managed Kubernetes cluster on Azure and open‑source apps, deploying Node‑RED, Postgres with nightly backups, Metabase, Mautic, SHLINK, Strapi + Next.js, and Prometheus/Grafana with Alertmanager to Discord. Handles 100,000+ students and ~10k events/month; integration platform cost drops from €500/month to ~€15, mail marketing from €8k/yr to €5k/yr, total spend falls from ~€14k/yr to ~€6k/yr (~46% savings). Runs reliably with ~2 hours/week maintenance; watch for DNS, volume and JVM memory pitfalls.
