The C4 Model - Misconceptions, Misuses and Mistakes

Explore common misconceptions, misuses, and mistakes when implementing the C4 Model for software architecture visualization in this 44-minute conference talk by Simon Brown, the creator of the C4 Model, recorded at GOTO Copenhagen 2024. Learn what the C4 Model actually is, why it was created, and how to properly use its notation and viewpoints. Discover solutions to frequent challenges when modeling databases, components, message-driven architectures, shared libraries, microservices, and micro frontends. Brown addresses concerns about C4 being "too limiting" and clarifies the difference between abstraction and organization in architectural modeling. The talk concludes with recommendations for tooling and practical advice for effectively documenting software architecture using the C4 approach, making it valuable for teams adopting this increasingly popular visualization method.
