Fictional example – not a customer result
Platform health
Traffic-serving service runs with a single replica
- Evidence type:
- Cluster configuration and customer interview
- Confidence:
- Medium
- Plan placement:
- 30 days
- Observation
- A traffic-serving deployment runs with one replica and has no matching PodDisruptionBudget. No separate failover could be confirmed from the material reviewed.
- Risk
- Node maintenance or a voluntary disruption can cause an outage if no other instance or external failover takes over. One replica is not automatically wrong, and two replicas do not prove high availability.
- Recommendation
- Confirm the workload's intended availability model. Then consider more replicas, a matching PodDisruptionBudget and topology spreading. Verify dependencies and actual failover separately.
- Verification
- Carried out by the customer in an approved test environment and agreed test window.
