What I talk about when I talk about Domain-Driven Design


Everyone who loves DDD claims that it makes things easier, but if that’s true, why do so many experience exactly the opposite?  And why do the mega-fans always seem to be architects?

DDD is back in the top 100 search terms on O'Reilly. But the fact remains, the thing called "DDD" is a massive edifice - a massive set patterns, tools, architectures, approaches, and concepts, all under one unifying philosophy.  And so the questions keep coming: "where do we start?", "we did this, what next?", and most importantly "isn't it just for architects?"

The time is right for both a survey of the DDD landscape, and a set of curated early steps which will help folks like you to take advantage of all the benefits DDD can bring.  I’m an O’Reilly DDD trainer, and in this talk I’ll introduce DDD in broad terms, covering all the main concepts. I’ll then discuss the relationships between these key elements. Finally, given all that, I’ll lay out pathways for your future DDD journey, whether you are an individual dev, or a dev lead, or even a chief architect.

Scheduled on Monday from 13:40 to 14:30 in Gallery Hall
