===== Internal VMs =====

Note 1: Although these VMs follow the //chemical elements// naming scheme, it's probably time to start using functional hostnames instead (save the names for bare metal).

Note 2: Where small applications are Dockerized and hosted together, they are grouped according to the people who require access. e.g. limited access to personal data, wide access to lab automation/IoT.
