The C4 model - misconceptions, misuses, and mistakes
The C4 model for visualising software architecture has been gaining traction, with many organisations adopting it as their preferred way to document software architecture. Although C4 is relatively lightweight and straightforward, there are several misconceptions that I see on a regular basis, and several common ways in which teams use C4 incorrectly. Join me for a tour of these things, and hear my advice on how to model things like shared code, microservices, and larger software systems.
Five things every developer should know about software architecture
The software development industry has made huge leaps in recent years, yet software development teams are often more chaotic than they are self-organising, with the resulting code being more of a mess than was perhaps anticipated. Successful software products aren't just about good code, and sometimes you need to step away from the IDE for a few moments to see the bigger picture. This session is about that bigger picture and is aimed at software developers who want to learn more about software architecture, technical leadership, and the balance with agility. This talk will debunk some of the common myths as we look at five things every developer should know about software architecture; a guide to modern software architecture that's pragmatic rather than academic and lightweight rather than "enterprisey”.
C4 models as code
"Diagrams as code", as featured on the ThoughtWorks Tech Radar, is becoming a popular way to create software architecture diagrams for inclusion in long-lived documentation. The benefits of creating diagrams from text are well understood - text is version controllable, easy to diff, easy to integrate into build pipelines, and automatic layout facilities allow authors to focus on content. The majority of these tools (e.g. PlantUML and Mermaid) are focussed on diagramming though, and require you to create one text file per diagram, with only a limited ability to reuse diagram elements across multiple diagrams. At scale, this causes maintenance problems, and leads to inconsistencies between diagrams.
This talk will introduce and demonstrate the open source Structurizr DSL - a way to create a model of your software architecture using a textual DSL that's specifically targeted towards the C4 model. We'll also see how the DSL separates content from presentation, allowing you to render your diagrams with a number of tools, which in turn offers some answers for the tricky question of how to use the C4 model at scale.
