Best Practices (HA, security, cost)

Practical guidance for reliable and efficient clusters.

High availability 🛡️

• Use multiple node pools across zones (if supported)

• Run ≥3 nodes for production workloads

• Prefer stateless services; use readiness/liveness probes

Security 🔐

• Enforce RBAC and least-privilege

• Apply NetworkPolicies; restrict egress where possible

• Keep clusters at N / N-1; patch base images regularly

• Store secrets in a secure provider; rotate tokens/certs

Cost 💰

• Right-size requests/limits; use HPA/VPA

• Autoscale node pools; scale to zero for dev jobs if supported

• Choose storage tiers to match I/O needs
