Sneak peek! Join the C4 model Patreon if you want to be the first to hear about it... 🤔 www.patreon.com/c/c4model

The #C4 model is a go-to for visualising software architecture, but how do you go beyond the basics? @simonbrown.je will answer the most common C4 questions, from modelling shared code & microservices to tackling message-driven architectures. #YOW25 MEL 4-5 | BNE 8-9 | SYD 11-12 Dec yowcon.com

Join @simonbrown.je in a 1-day hands-on #YOW25 masterclass on the #C4Model. Learn how to create meaningful diagrams that improve team communication and decision-making. 📍 MEL | 3 Dec | 🔗 yowcon.com/melbourne-20... 📍 SYD | 10 Dec | 🔗 yowcon.com/sydney-2025/...

Farewell "blue and grey boxes" ... the new example diagrams are now live on the C4 model website -> c4model.com

For those of you that use the #Structurizr DSL for publishing your #C4 Architecture diagrams and would like to use #dotnetaspire to add them to your AppHost. Then I have a NuGet package for you: www.nuget.org/packages/Str... #dotnet #aspire #nuget

New C4 model examples are on the way! See patreon.com/posts/132584... for details.

Moving fast and being Agile requires good communication, yet software development teams struggle with this fundamental skill. A good set of software architecture diagrams are priceless for aligning a team around a shared vision and for getting new-joiners productive fast: buff.ly/uX2tk38

I've updated the Structurizr DSL microservices example to take advantage of the new archetypes feature introduced a few weeks ago, which provides a richer and more concise DSL definition. The source can be found at github.com/structurizr/... if you're interested in taking a look.

Wrote a little on the C4 model and why I like it. On tumblr because why not :) www.tumblr.com/blmonit/7831...

A C1-level diagram in 30 minutes?! Amazing! From Ryan Shriver’s C4 model workshop at #ExploreDDD

The C4 model is simple—but are you using it right? @simonbrown.je dives into common C4 mistakes & how to better model microservices, shared code, and complex systems at #YOW25. 📍Mel 4–5 Dec | Bris 8–9 Dec | Syd 11–12 Dec 🔗 yowcon.com

The talk's tl;dr is that trying to optimise team performance via DDD, agile, Team Topologies, and all of the other socio-technical techniques will fail if you don't have good technical foundations in place. The backlash against architecture is real, but the technical leadership role never went away.

This article shares a pretty cool method for creating software architecture diagrams that actually make sense. Back when I was an engineering student, I really struggled with this stuff. This guide breaks it down in a super simple way. Totally worth a read—takes just five minutes!

Early bird pricing ends soon, so be quick!

If you're working on a complex software project, having good architecture diagrams really helps. And in this guide, Alex explains what the C4 model is & how it works. You'll go through each level - context, containers, components, & code - in detail. www.freecodecamp.org/news/how-to-...

Hey systems developers! What's stopping you from just typing in the code for this *architecture diagram* that a super cool AI made? Come on, get with it.

Show me an AI generated software architecture diagram and I'll tell you why it's bad. 😀 Seriously though ... if most humans are unable to adequately critique diagrams to determine whether they are good or bad, AI has no chance!

You can keep diagrams up to date if you use diagrams as *code* (e.g. Structurizr) rather than diagrams as *text* (e.g. PlantUML and Mermaid)…

This amazing group went for a morning run in the freezing wind before Day 2 of @devnexus.bsky.social #runWithJakartaEE #devnexus #EclipseFoundation

Most architecture diagrams suck. Not because of bad ideas... but because we're using the wrong tools.

More work on Structurizr DSL archetypes today ... relationship archetypes are now supported too.
