Cluster Architecture

The cluster consists of a k3s cluster, a dedicated bastion host running an nginx reverse proxy, and a dedicated NAS.

An interesting thing to note is that all server equipment (all hosts listed above) reside in a deticated VLAN to isolate them from other hosts on the network.

Although not exactly like an enterprise network, within my subnetting I have accounted for multiple physical locations, each with networks of servers, mobile clients, and normal clients.
