Yeah, but going from 1 to N instances is a big jump in complexity for not much more uptime.

I'd rather have a host that can do around three nines and just accept that as my upper bound.

The key moment is not to have any persistent state in the app. App may use a database, that's ok, but the app itself should not store any persistent state on a hard drive.

Once that simple requirement is met, the scaling becomes easy.

Right, but keeping a database externally adds a lot of complexity.

My apps are self-contained in a single Docker container. Just Go, SQLite, and Litestream:
