Quick checklist that saved us time. Rotate credentials on a calendar, not only after incidents. Run a pre-mortem; it surfaces surprises early.

Use feature flags generously for safe tests. Process tip that prevented a week of rework. Tighten feedback loops with weekly reviews.

I’d approach this a bit differently than most tutorials suggest. Automate sticky edge cases to save analyst time. We phased traffic: 5% → 25% → 60% → 100% to de-risk.

A thin rules layer filtered 80% of noisy alerts. Small anecdote that might help. Ensure sandbox parity to avoid release‑day surprises.

Watch hidden dependencies that slow audits. The real cost driver was reprocessing, not inference. Quick lesson from a compliance-heavy integration.
