The C4 Model - Beyond The Basics

The C4 model for visualising software architecture has been gaining traction, with many organisations adopting it as their preferred way to document software architecture. Although C4 is relatively lightweight and straightforward, there are a number of common questions I hear asked on a regular basis. Join me for a tour of these topics, and hear my advice on how to model shared code, microservices, message-driven architectures, and more. I'll also share some insights into scaling the C4 model - both when diagramming larger software systems and when diagramming an entire system landscape.
