Domain-driven design in Go requires a canonical structure with entities.go, repository.go, service.go, errors.go, types.go, and validators.go files. This separation ensures clear boundaries, testability, and maintainability across your domain layer while supporting scalable backend architecture.

Multi-tenant domains require four scoping patterns: organization-scoped entities shared across projects, project-scoped entities isolated per project, flexible entities supporting both, and global entities outside tenant isolation. Choosing the right pattern ensures data isolation and architectural consistency.

Cross-domain relationships in Go use professional aliases to decouple domain layers and prevent circular dependencies. This pattern maintains clean architecture boundaries while allowing domains to communicate through well-defined interfaces.

Yes. Domain-driven design scales effectively for Go backends with complex logic, multi-tenancy requirements, and cross-domain workflows. It provides structured entity design, service interfaces, and error handling tailored for backend scalability.

Entities define domain objects and business rules, repositories abstract data persistence operations, and services orchestrate complex business logic across entities. Together they create a layered domain structure that separates concerns and enables testing.

Refactor domain boundaries when entities share responsibility, cross-domain dependencies become tangled, or new functional requirements span multiple domains. Restructuring ensures each domain maintains single responsibility and clear interfaces for future scalability.
