Microservices is bad for teams without discipline to implement "separation of concerns". They hope that physical network boundaries will force the discipline they couldn't maintain in a single codebase. While microservices force physical separation, they don't stop "Spaghetti Architecture." Instead of messy code, you end up with "Distributed Spaghetti," where the dependencies are hidden in network calls and shared databases. Microservices require more discipline in areas like: Observability: Tracking a single request across 10 services. Consistency: Dealing with distributed transactions and eventual consistency. DevOps: Managing N deployment pipelines instead of one. For most teams Modular monolith is often the better "first step." It enforces strict boundaries within a single deployment unit using language-level visibility (like private packages or modules). It gives you the "Separation of Concerns" without the "Distributed Spaghetti" network tax.

> Observability: Tracking a single request across 10 services I'm not sure if this is a discipline issue in the way that domain driven design, say, is a discipline issue. If you instrument requests with a global ID and point at tool at it then you're basically done from the individual team perspective.

  Uh, that's not my experience at all. Sure you can say e.g "this property wasnt set in this request while being processed by this service managed by this team", but why it wasn't set will inevitably need multiple teams, each doing in-depth analysis how such as state could've been caused because they always inevitably become distributed monoliths - the former is being provided by the instrumentation, but the latter isn't (and even the former is not perfect, as not all frameworks/languages have equal support)
