Defining service boundaries involves identifying domains, actors, and ownership delineations across runtimes. This approach specifies which team owns each boundary and what runtime governs it, ensuring clear ownership and documented tradeoffs for backend systems.

You should separate logic across APIs, workers, and serverless functions when applying domain-driven design to multi-runtime systems. It helps decide what logic stays together and what should be isolated, capturing operational pros and cons to guide architectural decisions.

Yes, domain-driven design can be applied to monoliths to split responsibilities. By mapping domains and ownership boundaries, you can decide where logic should live and prevent scope creep and misaligned responsibilities during architecture decisions.

The best way to prevent scope creep is by clarifying service boundaries and ownership delineation. This ensures teams have defined responsibilities and documented tradeoffs across modules, preventing misaligned responsibilities during architecture decisions.

Documenting tradeoffs in polyglot architectures requires capturing the operational pros and cons of each boundary. This guides decision-making by mapping separation of concerns and specifying which runtime or contract governs each ownership boundary.
