Balancing Coupling in Software Design: Universal Design Principles for Architecting Modular Software Systems

Chapter 13

Balanced Coupling in Practice

A developer’s life is like an endless learning spree,

Yet patterns and principles are branches of the same tree.

From a method’s line, to the system’s high-level design,

The dimensions of coupling must be balanced and prime!

Chapter 12 explored the growth dynamics in network-based systems and explained why innovation is crucial for sustainable growth. You also learned how the theory of complex networks applies to software design. This chapter puts the theory into practice. It presents eight case studies that demonstrate the discussed concepts at different levels of abstraction, from microservices to methods. Each case study analyzes the design decisions made by teams and how they were improved by applying ...
