Architecture boundaries and dependency directionDefine boundaries around distinct responsibilities and make dependency direction protect the decisions that should remain independent.

Event-driven architectureCoordinate parts of a system through events when temporal decoupling and asynchronous reactions justify the added operational complexity.

Layered architectureOrganize a system into responsibility layers with explicit dependency direction and limited cross-layer knowledge.

Modular monolithKeep a system in one deployable unit while enforcing internal module boundaries and explicit dependencies.

Ports and AdaptersProtect application policy behind explicit ports so external mechanisms remain replaceable implementation details.
