Observability + Scale Readiness closure

Scale readiness means recoverable pressure, not perfect dashboards

Flow has reliability, incident, queue, provider and release evidence surfaces. This closure defines what is ready now and what needs live volume or real provider credentials before we can call it proven.

Current decision

90% ready, live volume proof pending

The operating model is strong. Final scale confidence needs a production-like soak, webhook storm with real connector credentials and SLO thresholds tuned against live traffic.

What must keep working under pressure

Ready with production-volume proof pending

Load and soak

Scale readiness surfaces separate dependency-aware load tests from real production-volume evidence.

  • load budget
  • soak window
  • p95 thresholds
  • tenant pressure

Green

Queue and webhook pressure

Webhook storm, queue pressure and provider backoff states have owner, retry and recovery visibility.

  • webhook storm
  • queue backlog
  • retry drain
  • dead-letter visibility

Green

Provider outage recovery

Provider degradation can be shown with customer-safe status, recovery ETA and next operational action.

  • degraded provider
  • fallback route
  • recovery ETA
  • incident owner

Green

Incident and SLO communication

Reliability console, incident history and public status give an operator path from alert to postmortem.

  • SLO health
  • incident timeline
  • customer update
  • postmortem path

Acceptance

Scale confidence checks

  • Ops can explain system health without reading raw logs.
  • Queue pressure and webhook storm states show owner, retry path and ETA.
  • Provider outage behavior is customer-safe and does not leak internals.
  • Scale tests are archived with thresholds and result status.
  • Incident communication has owner, timeline and postmortem path.
  • Production-volume proof is not faked before real traffic exists.

Remaining proof

Needs live volume or real providers

  • Run production-like soak test with target tenant mix.
  • Archive webhook storm proof against real connector credentials.
  • Capture one provider outage simulation with customer-facing recovery message.
  • Validate SLO thresholds against live traffic after first customer cohort.
