But the runtime is in the base image, so that is shared across all deployed services on the a single host system(s). So it's much less of an issue, also, the entire runtime isn't loaded into RAM for every application. From Task manager in windows, I'm running a local app in debug/dev mode and it's taking 226mb ram, which is a lot compared to IIRC well under 20mb for the last rust-axum project I wrote.

That said, you get a lot of functionality in the box and nearby out of that extra resource usage and it doesn't really grow by much under load.

Beyond that, there's nothing particularly wrong about having a mostly monolithic backend for a lot of things, I would say most applications are better served starting with a more monolithic backend in a mono-repo with the FE.
