Biggest risk is invisible complexity creeping in. Keep the system operable by the smallest competent team. Keep dependencies boring and well‑documented.

Small anecdote that might help. We phased traffic: 5% → 25% → 60% → 100% to de-risk. Add synthetic transactions to catch silent failures.

Keep dependencies boring and well‑documented. Quick checklist that saved us time. Write copy‑paste runbooks for common procedures.

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

Document assumptions so new teammates move faster. Run a pre-mortem; it surfaces surprises early. Process tip that prevented a week of rework.

Keep the system operable by the smallest competent team. Biggest risk is invisible complexity creeping in. Push data contracts upstream so APIs don’t drift.

Decide this with numbers, not vibes. If the key metric doesn’t move in 14 days, revert. We phased traffic: 5% → 25% → 60% → 100% to de-risk.

Quick checklist that saved us time. Shadow‑run the new stack for a week before go‑live. Ensure sandbox parity to avoid release‑day surprises.

Small anecdote that might help. We phased traffic: 5% → 25% → 60% → 100% to de-risk. If volume is spiky, budget for burst capacity explicitly.

Counterpoint based on what stuck in reality. Document assumptions so new teammates move faster. Ignore shiny features until you validate ROI.

Calm dashboards mattered more than fancy models during incidents. We shipped something similar last quarter; notes below. Automate sticky edge cases to save analyst time.
