It shows that the Internet banking system (the dashed box) is made up of five containers: a server-side web application, a client-side single-page application, a mobile app, a server-side API application, and a database. Below is a sample container diagram for the Internet banking system. Technology decisions are also a key part of this diagram.

Level 2, a container diagram, zooms into the software system, and shows the containers (applications, data stores, microservices, etc.) that make up that software system.
Colour coding in the diagram indicates which software systems already exist (the grey boxes) and those to be built (blue). The Internet banking system uses the bank's existing mainframe banking system to do this, and uses the bank's existing e-mail system to send e-mail to customers. Personal customers of the bank use the Internet banking system to view information about their bank accounts and to make payments. Here is an example of a system context diagram that describes an Internet banking system that you may be building: Level 1, a system context diagram, shows the software system you are building and how it fits into the world in terms of the people who use it and the other software systems it interacts with. It also considers the people who use the software systems that we build. The C4 model considers the static structures of a software system in terms of containers (applications, data stores, microservices, etc.), components, and code. To create these maps of your code, you first need a common set of abstractions to create a ubiquitous language to use to describe the static structure of a software system. Think of it as Google Maps for your code.

C4 stands for context, containers, components, and code - a set of hierarchical diagrams that you can use to describe your software architecture at different zoom levels, each useful for different audiences. After years of building software myself and working with teams around the world, I've created something I call the "C4 model". In our industry, we really should be striving to create better software architecture diagrams. Ionut Balosin last year wrote " The Art of Crafting Architectural Diagrams", which describes a number of common problems with doing this, related to incomprehensible notations and unclear semantics.Īmbiguous software architecture diagrams lead to misunderstanding, which can slow a good team down. These same teams now tend to rely on ad hoc diagrams that they draw on a whiteboard or put together using general-purpose diagramming tools such as Microsoft Visio. An unfortunate and unintended side effect of the Manifesto for Agile Software Development is that many teams have stopped or scaled back their diagramming and documentation efforts, including the use of UML. However, it's very likely that the majority of the software architecture diagrams you've seen are a confused mess of boxes and lines. Software architecture diagrams are a fantastic way to communicate how you are planning to build a software system (up-front design) or how an existing software system works (retrospective documentation, knowledge sharing, and learning).
