Show HN: Mapperly – A .NET source generator for object to object mappings

It all comes down to scale. I'm not endorsing splitting off logic into different applications for the sake of it - it is no better (usually worse) than splitting logic into separate modules for things that could've been "together". 34 microservices per just 15 people sounds like a lot of trouble unless those are really "lean", have little to no boilerplate and managing infra-side of things is automated away or outsourced to dedicated platform team.

To give a better example, recently on HN there was a discussion on self-hosting Bitwarden and its respective implementations. The official one[0] is written in C# and uses 15ish containers. The alternative one[1] is written in Rust and is a one application. I think both have their merits, since the former is used to serve possibly millions of users at this point, while the latter is best utilized in self-hosted home or SMB scenarios.

Services should be factored along scaling dimensions, not domain or team size. Ideally scaling and domain dimensions will be coupled to some extent, but that is not always the case. The popular idea that needs to die is that services are somehow tied to team size.

The latter has API equivalency, but that is not the same thing as feature parity. Plus, you have very different concerns when you want a small self-hosted app, vs a more “traditional” deploy model where integration and the like are more important, shaping the way you program.
