Assume your automation will run twice, crash midway, or receive the same event repeatedly. Use idempotency keys, upserts instead of inserts, conditional writes, and deduplication tables. Prefer deterministic naming and checksums for outputs to prevent accidental duplication. When re-runs are safe by design, recovery is just rerunning, not repairing. This simple discipline unlocks easy retries, stateless execution, and painless scaling across batches or concurrent workers.
Plan for intermittent failures and rate limits by using exponential backoff, jitter, and circuit breakers. Always set timeouts so a slow dependency does not stall your entire workflow. Keep retry counts modest and log final failures to a dead-letter queue for later inspection. By respecting upstream constraints, you avoid cascading overloads, earn goodwill from partner APIs, and maintain predictable service quality during surges or partial outages.
Design dashboards for decision-making, not decoration. Show throughput, latency percentiles, error rates, queue depths, and cost trends on one page. Add release markers to correlate changes with behavior. Include links to recent logs, runbooks, and on-call contacts. If a teammate can diagnose ninety percent of incidents using this page alone, you have succeeded. Keep it brutally simple, regularly reviewed, and free of graphs nobody understands or trusts in the moment.
Alert on symptoms users feel and states that require action, not every fluctuation. Use multi-condition rules, time windows, and deduplication to avoid chatter. Include context and runbook links so responders know exactly what to try first. Route alerts to chat during business hours and escalate thoughtfully after. Fewer, smarter pages preserve focus, reduce burnout, and make people treat alarms seriously instead of muting everything during crunch time.
