Enterprise Home Lab Architecture

A controlled infrastructure environment for systems administration practice.

The home lab centers on verified infrastructure components and support workflows: internet edge access, pfSense routing and firewalling, D-Link switching, Dell R710 compute, Proxmox virtualization, Windows Server services, Active Directory, DNS, DHCP, VPN access, and network monitoring concepts.

Purpose

Practice administrator-level troubleshooting across identity, network, virtualization, and endpoint-adjacent services.

Operational Value

Shows how infrastructure components relate to support tickets, service boundaries, remote access, and handoff documentation.

Hiring Signal

Demonstrates infrastructure operations progression without claiming production ownership of a live enterprise environment.
