Carola Lilienthal - Domain-Driven Transformation - how to improve the structure of legacy systems

Описание: Join us live in Berlin 2026 https://agile-meets-architecture.com

Today, we know how to start a new project on a greenfield site and how to build good architecture. But most of us work in projects that have been around for a long time and whose architecture is (to put it mildly) not all that nice. ""Monolith"" and ""Big Ball of Mud"" are the unflattering terms for such systems.

In this talk, I will introduce you to Domain-Driven Transformation, a methodology, which Henning Schwentner and I have developed over the last few years from our experience of improving legacy systems. Four steps lead from the evaluation of the current state to the domain-oriented vision of the architecture. We present a catalog of refactorings that help to heal BBOM architectures, anaemic domain models and poorly organized teams. Finally, I discuss our thoughts on the influence of certain domain properties on decomposition into subdomains.

Legacy software is a huge problem in many organizations because development and maintenance is slowed down up to completely stopped. With this method you will be able to improve the situation of your development teams.
