Evolving Wikipedia: A Case Study in Applying DDD - Moriel Schottlender - DDD Europe 2024

This talk will present a case study of utilizing Domain-Driven Design (DDD) methodologies to address the challenges of evolving Wikipedia's underlying system architecture. Wikipedia is a 23-year-old open-source monolith that serves billions of reads and millions of simultaneous writes, with a unique combination of dynamic user-generated content and workflows. The scale, complexity, and socio-technical nature of Wikipedia make it a challenging environment for applying DDD. This talk will discuss the process of mapping the system to understand potential pitfalls, discover opportunities, and inform product strategy.

I have tried to applied these DDD techniques in my work at New Relic and have not been near as successful as this work reported by Moriel Schottlender. Kudos to all involved.

Very good talk, it’s always interesting to learn about a tool that we use on a daily basis
