In a previous blog , we explored how this model for building stream-processing applications naturally shifts the application’s focus from the event stream to the data sources that are sending events. One indicator of a useful software architecture is that it provides unexpected benefits. See the diagram below.)

Over the past few years I have focused much of my learning and work choices around learning about the design of sociotechnical systems?—?how how to design software architectures and organise teams around them. As part of good design, we should consider the effects of changing all of these variables.

A trip to the supermarket can teach you a lot about designing software systems and shaping teams to build them… I was recently in need of some chocolate sauce. The Chocolate Sauce Heuristic for Software Design There are a few lessons about software development we can learn from this story, but I want to focus on design.

There are thousands of ways we can shape the software systems we build and organise our teams around them. Yet there is no flowchart we can simply follow to find the optimal design. Sociotechnical systems are complex systems formed of complex systems. We have the unpredictable nature of markets.

I’ve just created a new kata which you and your team/friends can use to practice your architecture and domain-driven design skills. This kata is split into four sections that address different aspects of architecting software systems. First with a domain quiz, and then by slicing up the provided event storm into domains.

I did a few talks on this subject early in the year, and linked this to the sustainability advantages of serverless architectures. The need for systems to be resilient is still increasing, and chaos engineering tools and techniques are developing as a key way to validate that resilience is working as designed.

Mapping out your business’s domain landscape has many benefits: knowledge sharing, generating product ideas, providing the foundation for software architecture, aligning on requirements, but a common challenge is… “where do we start?” The high-level structure is not design structure (e.g. Q: What is a domain landscape?

We had an interesting challenge on our hands: we needed to build the core of our app from scratch, but we also needed data that existed in many different systems. We decided to build our app based on principles behind Hexagonal Architecture and Uncle Bob’s Clean Architecture. We treat it as an input for our system.

The key to loose coupling is to understand how the system you are building is going to change, and minimising the cost of those changes. Is there any way it’s possible to predict the future so that our architecture can easily absorb the changes we need to make of it?

One of the biggest time costs in software development is understanding how a system works. Systems are getting more complex yet our ability to understand them doesn’t seem to be growing at the same rate. As we continuously develop software systems, the complexity slowly increases and we don’t fully realise it.

Techniques like big picture event storming are great for mapping out the business and visualising problems and opportunities, but that’s where progress can easily get stuck. How do you go from event storm to product and organizational improvements? One of the challenges I see regularly is inertia following domain discovery workshops.
