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.
