C4 Model, the Solution to Standardize My Architecture Diagrams?
summary
C4 explains its four diagram levels—context, container, component, code—and shows how limiting detail keeps architecture diagrams readable. A demo models a fictional Devoxx store (web frontend, catalog and order backends with separate databases and external payment/logistics) using Structurizr (local, CLI and cloud), workspace.dsl, decoupled model/views, theming and export options. The conclusion: diagram-as-code with Structurizr scales well for multi-application collaborative modeling but offers little benefit for a solo monolith.
