How to turn on billing and still sleep at night
summary
Upgrade to Blaze and set a concrete budget (example: $5/month) while watching the console show $0.34 Firestore, $0.02 Functions; 68k reads, 22k writes, 2.5k invocations. Link that budget to a Pub/Sub topic and build a Cloud Function that processes billing Pub/Sub messages and records state in Firestore so alerts fire only on meaningful changes (Pub/Sub pings ~20 min). Use Cloud Monitoring with sum aligner on 30‑minute periods and concrete alerts (e.g., >10k reads for 3 hours or ~8k reads over 5 minutes); infinite‑loop functions trigger and are stopped.
