Operate self-hosted Langfuse v4 LLM observability on six Vultr machines in one VPC — a self-hosted Neon storage tier for Postgres, a Redis host, three ClickHouse replicas with Keeper, and the application host behind Caddy and Cloudflare — with Cloudflare R2 for raw events, media, Neon layers and WAL, and backups that are restored and booted in a rehearsal.
