Static structure diagrams
The C4 model is named after the core set of static structure diagrams: (system) context, containers,
components, and code.
The different levels of zoom allow you to tell different stories to different audiences. That said, you don’t
need to use all 4 levels of diagram; only those that add value - the system context and container
diagrams are sufficient for most software development teams.
