V3 DDD Architecture

Applying Domain-Driven Design to a monolithic codebase breaks it into focused bounded contexts using domain decomposition and context mapping. This replaces god objects with modular boundaries and defines clean interaction points for improved scalability.

A microkernel architecture separates a system into a minimal core kernel and pluggable modules. This design supports core and optional domain plugins, enabling teams to extend capabilities dynamically without modifying the central orchestrator.

Context mapping defines domain boundaries and establishes stable interaction points between bounded contexts. This process creates clean interfaces that enable event-driven interactions and microkernel-based module wiring across separate domains.

Domain-Driven Design is needed for architecture reorganization when a monolithic orchestrator becomes a god object. It provides domain decomposition, context mapping, and interface design to reduce complexity and restore system maintainability.

A modular DDD architecture supports event-driven interactions by defining bounded contexts with clean interaction points. The microkernel-based module wiring enables domains to communicate through events while maintaining strict boundary separation.

Replacing a monolithic orchestrator with bounded contexts requires significant architecture reorganization effort. Teams must carefully define domain boundaries and context maps, while the microkernel pattern introduces wiring complexity for plugin extensions.
