Won’t automated rollbacks flap my production?

They will if you use a single noisy metric. Use two-of-three signals, small time windows, and burn-rate logic. Add minimum canary durations and require consecutive failures before aborting.

How do we handle database changes safely?

Use expand/contract migrations and feature flags around read/write paths. Deploy schema first, then code that can read/write both versions, backfill as needed, then remove old paths later.

What if our metrics backend is down?

Fail safe. Default to aborting promotion when metrics are unavailable. Keep a manual override with on-call approval for business-critical releases.

Is this overkill for small teams?

No. Start with one service, one canary step, one error-rate threshold, and a LaunchDarkly kill switch. You’ll see MTTR gains immediately.

Can we do this without Kubernetes?

Yes. Use ALB/NLB weighted target groups, Spinnaker or a simple deployer script, and the same metrics/threshold pattern. Feature flags work anywhere.
