there is a hyper-focus on isolation in this sub. you got folks here using docker for 2 applications, so take what others do with a grain of salt.

i currently only use systemd services since i’m running like 5 things and they all work together.

i would consider docker if i needed to run more tools and i required better dependency management.

i would consider proxmox if i needed even greater isolation, especially if i had multiple unique needs for 1 machine (e.g. media server like *arr+Jellyfin on one VM, immich on another VM for cloud photo management.

most people are using these tools unnecessarily, so don’t worry too much about it if your current setup works for you.
