Microservices Must Own Their Data Storage

Each Spring Boot microservice must maintain its own dedicated data storage using separate databases, JPA EntityManager configurations, or data source configurations and never share databases with other services to ensure data ownership and service independence.

Inter-Service APIs Must Be Well-Defined

Service-to-service communication must use explicitly defined APIs with OpenAPI/Swagger documentation, Spring Boot REST controllers with proper validation (@Valid, @RequestBody), and standardized request/response formats using DTOs to ensure reliable integration.

API Versioning Strategy Must Be Implemented

Inter-service APIs must implement consistent versioning strategies using @RequestMapping version parameters, Accept header versioning, or path-based versioning (/api/v1/) with Spring Web MVC to manage breaking changes across service boundaries.
