V3 DDD Architecture

A microkernel architecture establishes a minimal core system that loads pluggable domain modules, allowing you to extend or replace bounded contexts like health-monitoring or event-coordination without modifying the core codebase.

Migrating a monolithic codebase to modular DDD domains requires a phased extraction plan that progressively identifies core domains, applies clean architecture layering, and introduces event-driven domain events for loose coupling during the transition.

A microkernel pattern establishes a minimal core system that loads pluggable domain modules, allowing you to extend or replace bounded contexts like health-monitoring or event-coordination without modifying the core codebase.

You need to break down a monolithic orchestrator into bounded contexts when your codebase loses scalability and testability, requiring clear domain boundaries and clean architecture layers to manage complex domains like lifecycle-management independently.

You can apply DDD architecture to existing codebases by analyzing the monolithic orchestrator, identifying core domains such as task-management and session-management, and extracting them into modular domains with explicit boundaries and event coordination.
