C4 Model is a software architecture model that provides a simple, scalable, and flexible way to describe and visualize software systems. Developed by Simon Brown, the C4 model is designed to help software architects and developers communicate the structure of their systems in a clear, concise, and accessible way.
The C4 model consists of four main components:
- Context: This level of the C4 model describes the overall context in which the system operates, including the stakeholders and their goals, the environment, and the high-level boundaries of the system.
- Container: This level of the C4 model describes the individual components of the system and how they interact with each other.
- Component: This level of the C4 model describes the individual components of the system in more detail, including their responsibilities and dependencies.
- Code: This level of the C4 model provides a detailed view of the code that implements the individual components.
When to use C4 Model
The C4 model is designed to be used in any software development project where there is a need to communicate the architecture of a system in a clear and accessible way.
It is particularly useful in projects where there is a need to:
- Communicate the architecture of a system to stakeholders and team members
- Ensure that the architecture of a system is aligned with the goals and requirements of stakeholders
- Facilitate the creation of a common understanding of the system architecture among stakeholders and team members
- Provide a basis for architecture-centric development practices and design patterns
- Help stakeholders understand the overall structure of the system and the relationships between its components
In conclusion, the C4 model is a powerful and flexible way to describe and visualize software systems. It provides a clear, concise, and accessible way to communicate the architecture of a system, and is particularly useful in projects where there is a need to ensure that the architecture is aligned with the goals and requirements of stakeholders.
