Creating high-quality software is challenging due to a focus on solutions over understanding organizational context. Developers need to engage with stakeholders across contexts. However, stakeholder communication can lead to misunderstandings and conflicts, disrupting knowledge sharing. This often results in autocratic decisions by architects. Achieving sustainable and design decisions, it's more effective to employ visual techniques, improving collaboration with stakeholders.

Bounded Contexts spielen bei Domain-driven-Design-Diskussionen eine zentrale Rolle. Sie gelten als eine vielversprechende Lösung zur Modularisierung von Systemen, sei es in Form von Deployment-Monolithen oder Microservices. Doch die Anwendung in der Praxis bringt Herausforderungen mit sich: Es ist oft schwierig, eine Domäne sinnvoll in Bounded Contexts aufzuteilen. Zudem ist das Konzept nicht einfach zu verstehen. Einerseits steht es für die Aufteilung eines Softwaresystems in Module,…

Die Grundlage für gute Software ist eine gute Architektur. Eine zum System passende Architektur kann jedoch nicht im luftleeren Raum entstehen – um eine geeignete Architektur definieren zu können, muss man die Domäne und ihre Anforderungen verstehen. Moderne Architekturarbeit beginnt somit ein ganzes Stück vor der eigentlichen Architektur. Für diese Exploration der Domäne wurden im Rahmen von Domain-Driven Design (DDD) verschiedene kollaborative Modellierungstechniken entwickelt. Deren Ziel ist…

Today we know very well how to start a new project on a greenfield and how to build a good architecture. But most of us work in projects that have been around for a long time and whose architecture (to put it mildly) is not quite so beautiful. “Monolith” and “Big Ball of Mud” are the unflattering labels put on such systems.

This talk will show how we can introduce (or bring back) structure. Every system is different here, so it’s important to first understand where you are. Then the right steps…

Eric Evans' Big Blue Book has a chapter titled "closure of operations", largely ignored by the community and subsequent works on DDD. This is tragic, as closure of operations is one of the most powerful techniques for domain modeling. A concept imported from functional programming, it makes for flexible and long-lived domain models with the help of combinators - operations that build big domain objects from smaller ones recursively. This is refreshing alternative to the rigid hierarchical…

EventStorming, collaborative modelling, bounded context canvas - now what?

Did you ever feel like you're standing in front of a mountain of cloud tools and implementation options, with a well-designed domain model, but no idea where to start? Or are you fully equipped with technical understanding and cloud experience, but deeply unsure how to "cut" your system for good modularization?

Fear not, because this workshop will introduce you to a solid set of tried and proven methods and tools, that…
