C4 Model

The C4 Model is a framework for visualizing the architecture of software systems, created by Simon Brown. It uses a set of hierarchical diagrams to represent different levels of detail: Context, Container, Component, and Code (hence the name C4). This model helps in understanding and communicating the structure of a software system, from high-level interactions with external entities to detailed design of individual components. The C4 Model is valuable for architects, developers, and stakeholders to ensure a shared understanding of the system architecture.
