5 questions in Modular Monolith.

Quiz

A checkout path makes 40 calls across module boundaries to render one page. Roughly what does that path cost in a modular monolith versus the same modules extracted as services in one availability zone, and what does the number tell you about where to draw boundaries?

A product team of fifteen engineers must choose between a modular monolith and services. What should decide it?

A team adopts a modular monolith. What must they do forever, and what happens if they stop?

A team chooses a modular monolith over microservices. What makes the module boundaries actually hold, and what signals indicate it is time to extract a service?

What mechanically enforces module boundaries in a monolith, and what happens without enforcement?
