The Layered (N-Tier) Architecture Paradigm

When to Employ This Paradigm

• When teams need clear architectural boundaries and a familiar structure for moderate-sized systems.
• When compliance or operations teams require clear separation of concerns (e.g., UI vs. domain logic vs. persistence).
• When the deployment artifact remains a monolith, but code clarity and separation are degrading.

When NOT To Use This Paradigm

• When high scalability demands require independent scaling of components
• When multiple teams need independent deployment cycles
• When complex business logic requires frequent cross-layer communication
