Featured guides

Practical starting points for the highest-value topics.

Observability baseline

Give responders enough context to understand impact and isolate causes.

Emit structured logs with request, user-safe, tenant, and trace identifiers.
Measure request rate, errors, duration, and saturation.
Trace important work across service and queue boundaries.
Build dashboards around user journeys and service objectives.
Alert on actionable symptoms instead of every internal anomaly.

Key idea: Telemetry is useful when it helps answer a production question.

Safe retry policy

Recover from transient failure without multiplying the incident.

Retry only operations known to be safe or protected by idempotency.
Set a deadline and use exponential backoff with jitter.
Cap attempts and respect upstream Retry-After guidance.
Avoid synchronized retries and nested retry multiplication.
Record exhaustion and provide a dead-letter or recovery path.

Key idea: Retries shift load through time; they do not remove load.

Incident response

Restore service first, preserve clear ownership, then learn.

Declare severity and assign incident lead, operations, and communications roles.
Establish impact, recent changes, and a timestamped incident document.
Mitigate through rollback, disablement, failover, or controlled degradation.
Communicate on a predictable cadence until recovery is verified.
Write a blameless postmortem and track prevention work to completion.

Key idea: During an incident, coordination is a technical capability.
