A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

Being a noob and all I was wondering whats the real benefit of having a monolithic lets say proxmox instance with router, DNS, VPN but also home asssistant and NAS functionalitiy all in one server? I always thought dedicated devices are simpler to maintain or replace and some services are also more critical than others I guess?

This is the way.

There's nothing worse than finding your DNS/DHCP has gone down and it's a VM / container running inside a server that can't start because it doesn't have an IP address and you can't resolve names to get the thing started.

Break things down into chunks that make sense - to you.

I have dedicated (low power) hardware for the interweb firewall / DHCP / core network stuff.

I have a NAS for storage with all the backups / reinstall images on (so I can rebuild the firewall if there's no internet, for example)

Then I have everything else in a single server.

Sources: a house fire, water leak & many hardware failures & borked upgrades over many decades.
