I run my homelab like a miniature data centre — here's the network design that made it possible

Short summary

Author redesigned homelab from flat network to datacenter-style architecture with VLANs after deploying an Akash Kubernetes provider. Each workload gets dedicated /24 subnet, firewall policy, and isolation; inter-VLAN traffic denied by default. Pattern enables per-workload security policies using hardware-accelerated routing on a Cisco Nexus switch.

  • •Evolved from flat network to segmented datacenter design to handle multi-tenant Akash provider deployment
  • •Each workload VLAN isolated with dedicated /24, firewall rules, and zero default inter-VLAN trust
  • •Implementation uses Cisco Nexus L3 switching with hardware ACLs for policy enforcement at line rate
