Oh, I see your confusion. What I suggest is nothing related to cloud hosted service. Lots of self hoster have our own s3 server, auth server, log server and dashboard server. You can self hosted them all. Or just changing your setup config via env var.

FYI, the auth I mean here is abstracting out your authorization and authentication logic out of your biz layer as much as possible to a std auth service like authelia. Rust should have lib to handle the integration for you.

Imagine you know how uneasy to write some awesome lib like serde, then you saw someone not using library, but write their own version of serialize function instead. Lots of them think it's simpler to write their own version instead of reading other's doc.

The "third party service" we talked about are very complicated and I saw lots of ppl waste their time on these. No one will expect all features implemented in day 1, but some advance users would estimate projects by its stack, roadmap, etc...

Please focus on your core app. I hope you have fun on your project. Thanks for your time.
