Phase 3 · Ch 5 — Enterprise Cluster Infrastructure & Networking

Chapter 5: Enterprise Cluster Infrastructure & Networking

Coming soon. This chapter covers multi-master HA topologies, etcd backup/restore, Cilium eBPF networking, sophisticated scheduling controls, and zero-downtime operations.

Planned Topics

  • High Availability (HA): Multi-master architecture (stacked vs. external etcd), etcd backup/restore, maintenance
  • Modern CNI Architecture: Cilium eBPF kernel-level routing vs. Calico iptables; IPAM planning
  • Sophisticated Scheduling: Taints and Tolerations, Node Affinity/Anti-Affinity, Pod Topology Spread Constraints
  • Zero-Downtime Operations: PodDisruptionBudgets (PDB), terminationGracePeriodSeconds, preStop hooks
