Google Cloud Run: run containers without managing servers

Cloud Run lets you run containers without managing servers — it autoscales, even down to zero when there’s no traffic.

Why it’s appealing

• Pay per request: near-zero cost when idle.
• Autoscales from 0 to thousands of instances.
• Any container that listens on PORT just works.

Deploy quickly

gcloud run deploy my-app \
  --source . \
  --region asia-northeast1 \
  --allow-unauthenticated

Things to watch

• Containers should start fast (cold starts affect latency).
• Don’t keep state in memory — use external services (Cloud SQL, Firestore…).
