Insert diagram: Multi-zone web tier with LB + DB

Web/API (stateless)

• LB → instances across zones (where supported)

• Store sessions in Redis or use cookie stickiness

Database

• Primary/replica with automated backups and snapshots

• Isolate on Premium/Pro volumes; enable monitoring alerts

Kubernetes

• ≥ 3 nodes spread across zones

• Ingress + readiness/liveness probes

• Persistent volumes via CSI

Networking

• Separate public/app/db subnets

• Strict firewall rules and NetworkPolicies
