I've got a mix of hosting environments personally. A dedicated box hosted with Hetzner (their auction prices can be pretty decent) plus a Pi 4 and an old NAS for internal services. Docker containers used for pretty much everything - mostly set up with a big ol’ /opt/ folder with a bunch of service specific folders with docker-compose.yml files and bind mounts galore. Got a wireguard VPN bridging between then because that seemed sensible.

Running Portainer for some extra management and monitoring, then a bundle of stuff:

• Mailcow for email
• Owncloud for for sync and storage
• Phototropism
• Bitwarden
• Emby for media playback
• NextPVR for recording
• Private instances of Pleroma and Lemmy
• A slightly broken telegram/grafana stack with some container monitoring stuff hooked in
• The odd dedicated game server when the need arises ... and some things I've forgotten about.

Got a spare old i5 machine around set up to auto hook into Portainer if I need some extra grunt at some point, but it's more likely to be used when I can't be bothered paying for the dedicated box.

Aware a lot of it's suboptimal, but it's easy to work with and familiar, and that's enough to make it workable.
