As always, Discourse is many steps ahead of the industry, yesterday I’ve tested the full transition to ARM based servers and it was successful! Saving hundreds of dollars per month on server/electricity costs!
But as I’m not a real ruby developer, on top of that I don’t know too much about how packages compatibility and missing dependencies may affect the reliability of our Discourse setup in terms of functionality and security.
May I ask, is discourse on ARM64 battle tested and officially reliable for serious production loads, or should I stick with x64 for now?
While we use ARM for PostgreSQL and Redis production hosting, and we have made the Ruby app ARM64 compatible since Discourse on a Raspberry Pi | Blog, we don’t host production traffic from our hosting in ARM yet.
That said, as long as you can safely store database backups off-site and monitor the website for error/response times reliably, it should be safe to give ARM in production traffic.
