My personal machines are all pets ("thematrix", "heartofgold", "laputa" and "isengard") and my production systems are cattle ("sqldb01", "sqldb02", "gitea", "redis0", "redis1", "rabbitmq", "mastodon", etc.)
Mostly because for automation it's easier to know what a system does by looking at the hostname. When you manage about 30 systems all over the place, that's the only reasonable solution (I do see people trying to give pet names to their production systems but it gets out of hand and they usually just maintain a directory of what system does what somewhere)
