- keep inventory in a DCIM (we use Netbox)

- configure everything as code (we use Ansible for the infrastructure up to OS level, Kubernetes w/ Helm for applications), have it read the values from the DCIM so that the DCIM remains the single source of truth (we need to still get better on this part....)

That's at work. At home, I do much of the same, except that maintaining a DCIM is excessive for 2 VPS and a home network of 3 boxes.
