Mastering Microservice Orchestration with Pub/Sub

on YouTube ↗25m

" summary

Shows how to replace a slow sequential order flow with event-driven processing using Google Pub/Sub and service accounts + JWT auth, publishing a base64 JSON message to a topic and delivering to many push subscription endpoints in ~0.5s in the demo. Covers topic/subscription setup, schema, ack deadlines, retries (typically 5–10) and a dead letter topic with e.g. 30 day retention. Warns of at‑least‑once delivery and duplicates so include an idempotency key or use Cloud Tasks for stricter rate control.
