Production-oriented single-machine Temporal at bigconfig.online.
An Amsterdam c-8 Droplet runs PostgreSQL 17, Temporal Server 1.31.2, the TypeScript SDK 1.22.0 reference worker/API, and Caddy. Only HTTPS and operator-restricted SSH are public.
Workflow history survives service and Droplet restarts in PostgreSQL. Automated acceptance verifies HTTPS, duplicate rejection, activity retries, deterministic results, and recovery during a durable delay.
This is one failure domain, not HA. Daily local SQL dumps and DigitalOcean backups support operator-led recovery; there is no automatic failover. See the repository runbook.
