Microkernel (Plugin) Architecture

Every software system eventually faces the same challenge: new requirements arrive after the core is built.

A payment system needs to support a new payment provider.

A code editor needs to support a new programming language.

A data processing platform needs to support a new output format.

An e-commerce platform needs to support a new shipping carrier.

The naive approach modifies the core system for every new requirement. Each modification adds complexity. Each new payment provider adds more branching logic to the payment module
