A Better Way to Explain Modern Architecture Using the C4 Model

This article addresses the common problem of architecture diagrams becoming cluttered and unhelpful as systems grow. It introduces the C4 model (Context, Containers, Components, Code) by Simon Brown, which uses separate diagrams at different abstraction levels for different audiences. The Context diagram provides a high-level overview for stakeholders, Containers show deployable units for architects and DevOps, Components detail internal structure for developers, and Code zooms into specific implementations. The article emphasizes that diagrams should prioritize communication over visual complexity, making it easier for product managers, new developers, and engineers to understand modern tech stacks.
