The C4 model The C4 model is a lightweight approach created by Simon Brown to help software development teams describe and communicate software architecture, both during up-front design sessions and when retrospectively documenting an existing code-base. It has been a very busy last couple of months where I am helping pull together an architecture for a massive transformation project. Diagrams as code. Visualise. Just like on a Google Map. @startuml(id=AmazonWebServicesDeployment) title Spring PetClinic - Deployment - Default caption An example deployment diagram. Use Local Copy of C4 Templates. C4 model diagrams capture the three levels of design that are needed when crafting any general software or business system. Yes No C4-PlantUML combines the benefits of PlantUML and the C4 model for providing a simple way of describing and communicate software architectures – especially during up-front design sessions – with an intuitive language using open source and platform independent tools.. C4-PlantUML includes macros, stereotypes, and other goodies (like VSCode Snippets) for creating C4 diagrams with PlantUML. I’ll let Simon describe it himself: The C4 model was created as a way to help software development teams describe and communicate software architecture, both during up-front design sessions and when retrospectively documenting an existing codebase. plantuml.includepaths: Specifies the include paths besides source folder and the diagramsRoot. A first look at the C4 Model web site piqued my … GCP Architecture Diagramming using C4. For example, here's a System Context diagram to describe a pet clinic information management system. GCP Architecture Diagramming using C4. PlantUML and C4 can be used to produce cloud architectures, there are official libraries available through PlantUML for Azure and AWS service … PlantUML can be extended to support the C4 model for visualising software architecture. C4 is a model that helps us look at applications from different perspectives. plantuml.jarArgs: jarArgs allows you add arguments to plantuml.jar, such as -config plantuml.config. C4 Diagrams. The C4 notation is very simple compared to other modelling notations. The C4 model is an "abstraction-first" approach to diagramming software architecture, based upon abstractions that reflect how software architects and developers think about and build software. It is not formal UML e.g. Simon Brown’s C4 Model tries to address some of the genuine concerns about unmanageable documentation by providing guidelines for visualising systems with information which is useful at different levels of detail. Example: (You can edit the text if you want, the diagram will be dynamically updated!) Lightweight supplementary documentation using Markdown or AsciiDoc to complement the software architecture diagrams. There are zillion stakeholders … The C4 model for visualising software architecture Context, Containers, Components and Code diagramming methodology is an alternative to UML, this particular example taken from here. PlantUML and C4 can be used to produce cloud architectures, there are official libraries available through PlantUML for Azure and AWS service icons, however these do … Images can be generated in PNG, in SVG or in LaTeX format. A web-based UI; recommended for non-programmers Demo. Shapes used in C4 notation. View via PlantUML. Supplement the architecture model with a log of the key decisions (e.g. It’s a way to … PlantUML. Overall, C4 strives for clarity and communication of the story, and follows Shneiderman’s mantra: Overview first, zoom and filter, then details-on-demand. For each of the template files C4Context.puml, C4Context.puml, C4_Component.puml comment out the includeurl, and uncomment the include, directive. Step up the C4 Model. It provides a framework to visualize the static structure of the software architecture in a top-down approach, but with only a small set of meta-data and diagram types. C4-PlantUML C4 syntax support for generating plantuml diagrams. PlantUML can be extended to support the C4 model for visualising software architecture.
