i agree that its possible. From what i've seen its probably harder though than just doing services. You are fighting against human nature, organizational incentives, etc. As soon as the discipline of the developers, or vigilance of the dictator lapses, it degenerates.

It is really hard to read this for me. How can anyone think that it is harder to write a proper monolith than implementing a distributed architecture?

If you just follow the SOLID principles, you're already 90% there. If your team doesn't have the knowledge (it's not just "discipline", because every proper developer should know that they will make it harder for everyone including themselves if they don't follow proper architecture) to write structured code, letting them loose on a distributed system will make things much, much worse.

its not really a technical problem. As others have mentioned on various threads, its a people coordination problem. Its hard to socially/organizationally coordinate the efforts of 100s of engineers to a single thing. It just is. If they're split into smaller chunks and put behind relatively stable interfaces, those people can work on their own on their own thing, roughly however they want. That was a major reason behind the original bezos service mandate email. You can argue that results in a harder overall technical solution (distributed is harder than monolith) but it is inarguably to me much easier organizationally.

You can sort of get there if you have a strong central team working on monolith tooling that enforces module seperation, lints illegal coupling, manages sophisticated multi deployments per use, allows team based resource allocation and tracking, has per-module performance regression prevention, etc. They end up having many of the organizational problems of a central DBA team, but its possible. Even then, I am not aware of many(any?) monoliths in this situation that have scaled beyond 500+ engineers that people are actually happy with the situation they've ended up in.
