Benjamin Nothdurft | Devoxx

Devoxx UK 2019
from Wednesday 8 May to Friday 10 May 2019.

Benjamin has a long-term and hands-on experience with introducing, building, running, coaching and speaking about Java, Microservices (including DDD and SCS – self-contained systems), Docker/Containerization and disruptive technologies. At day he works as Technical Lead for Cloud Technologies at codecentric. At night he hacks on innovative trends like FaaS, Service Meshes, Voice UIs and IoT. At evenings/weekends he organizes workshops, talks, hackathons and code retreats at the Software Crafters Community Jena (Softwerkskammer Jena), the Java User Group Thüringen and Devoxx4Kids Thüringen. He serves as a board member at the Java Aktuell Magazine, at microXchg and JavaLand conference – leading the Architecture and Methodology streams.

Applying (D)DDD and CQ(R)S to Cloud Architectures

Deep Dive

Many software architectures may benefit from the introduction of (Distributed) Domain-Driven Design and Command Query (Responsibility) Separation. No matter if you are maintaining large legacy software systems whether you start a new microservices platform as greenfield approach one always has to think about the domain language and service design. In this session I want to show you at a given example application how to get started with introducing domain models, bounded contexts and implementing CQRS where it makes most sense while trying to avoid the technical debt trap e.g. misconceptions and fallacies.

The session consists of several parts which outline the theory behind the building blocks in conjunction with according real world implementation examples. The provided code is based on modern technology standards: Java, Kotlin, Spring (Boot, REST, JPA, Messaging), RabbitMQ, Kafka, MySQL, Elasticsearch, Docker, Kubernetes.

At the end you will be able to apply many DDD principles on your own and have learned how to tailor systems according to their domain – effectively and efficiently.
