The C4 Model - Misconceptions, Misuses and Mistakes

Explore misconceptions, misuses, and mistakes surrounding the C4 model for visualizing software architecture in this 41-minute conference talk by Simon Brown, creator of the C4 model and author of "Software Architecture for Developers." Gain insights into proper modeling techniques for shared code, microservices, and large-scale software systems. Learn about the core concepts of C4, including its lightweight approach, notation, viewpoints, and abstractions. Address common criticisms and limitations of the model, and discover how to effectively apply C4 to various architectural patterns such as message-driven architectures, micro frontends, and modular monoliths. Understand how to scale the C4 model for complex systems and manage dependencies to external containers. Walk away with practical takeaways to improve your software architecture documentation and visualization skills using the C4 model.
