To structure a scalable Django REST Framework project, use split settings for dev/test/prod environments, dedicated project directories, and service layers to separate business logic from viewsets and serializers for maintainable production applications.

You implement custom QuerySets and managers in Django to encapsulate reusable database query logic, ensuring robust data layers with proper field indexing and constraints for complex ORM filtering and retrieval operations.

Use caching strategies and signals in a Django application to handle performance bottlenecks and model lifecycle events, but avoid premature optimization by applying them only when production-ready conventions demand it.

Yes, this Django architecture guidance covers middleware patterns and security best practices, providing production-ready conventions for request handling, logging, and middleware configurations to ensure robust web applications.

To design secure Django REST APIs, implement serializers with data validation safeguards, use viewsets with custom actions, and isolate business logic in a service layer to handle requests securely.

Without a service layer in Django applications, business logic bloats viewsets and models, making production applications brittle, hard to maintain, and lacking consistent architecture, ORM usage, and DRF conventions.
