Selfhosted
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:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
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.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

It’s really hard. And really expensive. I used to work in five nine environments, life or death type use cases, and my rule of thumb was that you double your cost for every extra nine you add.
When we got to five nines it was multiple hot standbys with a custom control and orchestration plane - literally custom hardware we had to build. This was for local installations, so not modern cloud environments (it was over a decade ago), but many of the challenges are similar, like session handling, transmission replay and caching, locking, clashing, routing, jitter, latency etc.
Looks like it is very stressful to work when you need this amount of availability, even more with the pressure that a little error can cause giant consequences.
Thanks for your answer!
I'm sorta surprised that it's only 2x per nine. Six or seven nines sounds ridiculous.
