C4 Model

The C4 Model is a way to visually describe software systems by breaking them down into four levels of diagrams, each showing different details. The levels are: 1) Context, showing the overall system and how it interacts with users and other systems; 2) Containers, illustrating major parts within the system, like applications or databases; 3) Components, focusing on key parts inside each container; and 4) Code, providing detailed diagrams of individual pieces of software. This layered approach helps teams understand, communicate, and manage complex software by clarifying how all parts fit together at different scales.
