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

Auteur

Vlad Khononov is a software engineer with extensive industry experience, working for companies large and small in roles ranging from webmaster to chief architect. His core areas of expertise are distributed systems and software design. Vlad consults with companies to make sense of their business domains, untangle monoliths, and tackle complex architectural challenges.

Vlad maintains an active media career as a public speaker and author. Prior to Balancing Coupling in Software Design, he authored the best-selling O'Reilly book Learning Domain-Driven Design. He is a sought-after keynote speaker, presenting on topics such as domain-driven design, microservices, and software architecture in general.

This book identifies the deeper problemGÇöhow software architects and designers approach coupling GÇô and introduces an important new approach for creating more successful designs whether you use microservices or not. Instead of blindly avoiding coupling, leading software architecture expert Vladik (Vlad) Khononov proposes a novel method that transforms it into a powerful design tool: GÇ£balanced multi-dimensional coupling.GÇ¥ Khononov begins by surveying existing methods of evaluating coupling, and illuminating their strengths and limitations in the context of modern distributed systems. Next, he introduces a new multi-dimensional coupling model, and demonstrates how to harness it to build modular software.

Instead of focusing solely on a single approach, Balancing Coupling in Software Design illuminates underlying design principles that are ubiquitous in SOA, microservices, DDD, design patterns, and other paradigms, revealing how each of them can fail if thoughtful design principles for coupling are neglectedGÇöand how balanced coupling can make all of them work more effectively.

Résumé

Harness the Power of the Multi-Dimensional Coupling Model as a Tool for Architecting Modular, Evolvable Software Systems

In this definitive guide, Vlad Khononov introduces a novel approach to designing modular software systems that turns coupling into a powerful design tool.

Software, like all systems, is composed of components that interact to form the system itself. Coupling is the metric used to represent the interdependence between connected components, and the magnitude of coupling ultimately affects the adaptability and success of the software system. Balancing Coupling in Software Design surveys existing methods of evaluating coupling and combines them into a comprehensive model for making design decisions that manage complexity while increasing the modularity of your software system.

Coupling is everywhere in software development. Whatever your job level or title, whether you are writing a function, designing an object model, or architecting distributed systems, this book is for you.

• Understand coupling and the ways it manifests itself in software design
• Evaluate the multi-dimensional forces of coupling
• Understand how the dimensions of coupling interact to impact your system
• Steer your systems away from complexity and toward modularity
  The principles discussed in Balancing Coupling in Software Design are ubiquitously relevant in software engineering and will transform the way you think about software design.
