👉 Nested engineering refers to the hierarchical and layered approach in software development where one system or component is designed and integrated with another, often at multiple levels of abstraction. This process involves creating a framework or architecture that supports the development and integration of various subsystems, each with its own specific functionalities. For example, in a complex application, the core business logic might be nested within a microservice architecture, where each microservice handles a distinct business function and communicates with others through well-defined APIs. This nested structure allows for modular development, easier maintenance, scalability, and the ability to update or replace individual components without disrupting the entire system. By breaking down the overall system into manageable, nested layers, engineers can focus on specific aspects of the project, ensuring that each part is robust and well-integrated with others.
