The original headline is "Two Kubernetes Decisions Nobody Writes About Honestly"

Short summary

When sizing Kubernetes nodes, many smaller nodes reduce failure blast radius—a failed node affects less workload and rescheduling completes faster. Readiness and liveness probes must be separate to avoid cascading restarts during external service degradation; combining them creates restart loops. Both decisions optimize for different failure modes: choose based on whether you prioritize resource efficiency or resilience.

• •Smaller nodes (higher count) reduce failure blast radius compared to fewer large nodes
• •Readiness and liveness probes must be distinct to prevent restart cascades
• •Balance resource efficiency against resilience based on your actual failure mode risk
