These diagrams help provide a big picture overview.

Context (level 1): Context diagrams are high-level, conceptual descriptions of what your system does, what problem it solves, the people involved, and any external systems that interact with it.

The C4 model is an architectural documentation standard for software systems that breaks a software system down into four levels:

Make it easier to identify potential flaws or areas for improvement in the software architecture.

Highlight critical system interactions and relationships.

You also want your diagram to be as self-explanatory as possible so that anyone looking at it can immediately see the relationships, constraints, and limitations in your software system without needing to ask you what something means. “There is nothing in the programming field more despicable than an undocumented program.” This can help developers see how the project developed and document that workflow to improve later.

Backward design involves diagramming after the code has already been written.

This has the benefit of helping your developers better visualize the system they’re trying to create.

Forward design entails creating your diagrams before you or your team starts coding.

High-level architectural diagrams and thorough documentation can be effective tools for communicating the internal state of a system or application when done well.ĭiagramming before you start coding and diagramming after your code has been written will also confer different benefits. You want your diagram to quickly convey a software system’s essential composition and behaviors to both technical and non-technical audiences. Good software architecture diagrams are sources of truth and clarity. What do good architectural diagrams accomplish?

Similarly, thorough software architecture can help your engineers quickly locate and fix bugs. To extend Danny Thorpe’s cave analogy, having a cave system thoroughly mapped out can make a huge difference if, say, your spelunking trip has gone awry and you’re waiting for rescuers to find you. Choosing the right architecture for your software will lead to stabler performance under stressful conditions as you scale up.Įven if you don’t anticipate an increase in users, thinking about the big picture for your program and how you can communicate that vision to others can help you and your team makes strategic decisions based on the impact that those decisions will have on your overall architecture. Having a great architecture lays the groundwork for how you will deal with performance, fault tolerance, scalability, and reliability in the future. “Programming without an overall architecture or design in mind is like exploring a cave with only a flashlight: You don’t know where you’ve been, you don’t know where you’re going, and you don’t know quite where you are.” Software systems can often contain multiple architectures.

Software architecture encompasses the organization of a software system, structural elements, behavioral elements, and the composition of those elements into larger subsystems. Software architecture describes the fundamental concepts and properties of a system within the context of its environment, relationships, principles of design, and more. We’ll also go over what a good architectural diagram should accomplish and why you should take the time to create one.

Today, we’ll focus on how to diagram, some examples of popular software architecture patterns, and places to find reference architectures to use as a starting point for various use cases. Software architecture diagrams are an important documentation practice that will help you plan for and implement changes in your network, visualize strategic initiatives, and stay ahead of your organization’s needs. The first step toward implementing a new software system is the architecture diagram.Īs software systems and web applications have become increasingly complex, well-designed system architecture diagrams have become critical for communicating with other developers and stakeholders. A software’s architecture is the foundation for any successful software system and will influence everything from maintainability, scalability, stability, and security throughout that system’s lifecycle.
