Talkat DDD Europe 2025 · 2025-06-02..06-06· [documentation, software-architecture]
slides:none on file

C4 evolves from hands‑on teaching to over 200+ clients across 40 countries, offering concrete rules for when to use component versus container diagrams, how to handle C4 notation fixes for microservices and shared libraries, and measurable guidelines on model granularity and versioning. Includes real misuses, a set of reusable templates and anti‑patterns, and examples showing where C4 scales cleanly and where it breaks so teams can pick what to adopt.
