The Microkernel (Plugin) Architecture Paradigm

When To Use

• Building extensible systems with plugin architectures
• Products requiring customer-specific customizations

When NOT To Use

• Monolithic applications without plugin extensibility needs
• Systems where all features are core and tightly coupled by design

When to Employ This Paradigm

• When building platforms, Integrated Development Environments (IDEs), data ingestion pipelines, or marketplaces where third parties need to extend core functionality.
• When the core system requires extreme stability, while extensions and features must evolve and change rapidly.
• When isolating optional dependencies and sandboxing untrusted code provided by plugins is critical.

Adoption Steps

1. Define Core Services: Clearly delineate the minimal responsibilities of the microkernel, such as scheduling, component lifecycle management, core domain primitives, and messaging.
