Three pillars that take you from individual lessons to running production-grade systems.
Monitoring
Telemetry, dashboards and alerting with Prometheus, Grafana, Loki, Tempo, Parca and Alloy. Build SLO-driven observability for production services.
Operations
Provision, deploy and operate infrastructure with SaltStack, OpenStack, Kubernetes, Helm, ArgoCD, Backstage and SOPS.
Authoring
Build production Wagtail websites — Bootstrap theming, structured content, reusable components and a content-first workflow.
Featured lessons
Short, self-contained activities that work as a first step in their topic.
Prometheus introduction
Architecture, scrape model, label data model and PromQL fundamentals — the entry point to the rest of the monitoring path.
Introduction to ArgoCD
GitOps reconciliation loop, Applications, sync waves and health checks — the foundation of the Operations path.
Introduction to Wagtail
Wagtail concepts, pages vs. snippets and the StreamField content model — the kickoff for the Authoring path.
Top paths
Curated multi-lesson courses bundled around a real production scenario.
