Round 92

Service Boundary Strategy

A software platform is being split from a monolith into services. The team must choose an architecture that supports faster feature delivery, keeps operational complexity manageable, and preserves reliability during the transition. Constraints: the system handles mixed read/write traffic, has several domain areas with uneven change rates, and the team has moderate DevOps maturity rather than deep platform expertise. The decision should balance delivery speed, runtime isolation, data consistency, team autonomy, and long-term maintainability. Reasonable experts may disagree on how aggressively to decompose the system, how to manage shared data, and how much infrastructure complexity to accept early.
