What are the typical boundaries for a microservice?

Short answer: Domain Boundaries: Align services with business domains (e.g., payment, user management). Data Boundaries: Each service should manage its own database to ensure independence. API Boundaries: Services should interact with others via well-defined APIs. Scaling Requirements: Services should be decoupled based on their individual scaling needs.
