Comprehend the complex with C4 model examples

Commonly used by software and program designers, C4 model architecture breaks down the building blocks of a system by descending hierarchy. The C4 container diagram (or model) showcases the four Cs—which stand for context, container, component, and code—and how they interact with one another on each different level.

This diagram type comprises four key categories, a C4 concept simplifies and organizes the intricate pathways making up systems.

Context, the first C, can be found at the top of the diagram. It conveys the overall intention of a system. Next come containers, which contain data and encapsulate what comes below. Beneath the containers, you’ll find components, which logically cluster code by purpose. Code, of course, is the final C.

When it comes to drawing a C4 model for software architecture, start with a customizable FigJam template. From there, it’s easy as 1, 2, 3.

1. First, you’ll want to title your model with the name of the system you’re depicting. The title sits at the top of the page for all to see.
2. Once you’ve chosen the system in question and labeled your diagram with its name, it’s time to add information. Start with the first C, context. This identifier acts as mission control for the rest of the chart, floating above info to remind you of your goal.
3. After you establish the system context, head to containers, and below them, components. The final row of your pyramid-esque model holds code. Using the FigJam template you can easily insert these various elements into their corresponding ovals.

With the fundamentals of your C4 model completed, you’re ready to elaborate. Work with your team to review your model for accuracy. Then take full advantage of your new systems roadmap to create cleaner, clearer systems.
