19:00 - Insights into the Machinery of a Continuous Delivery Pipeline - Automated Test Result Aggregation and Analysis for DevOps
Project Overview: We are developers in a dedicated release and test automation team that runs a continuous delivery pipeline for a leading eCommerce platform (currently running approximately 170,000 stores).
Due to the large number of pipeline machines (for the respective installation and patch types), the time required to evaluate test results (selenium) has increased significantly over the past year. As automation specialists, we have decided to introduce a centralized database for all test results that are generated by the hundreds in each pipeline run.
Our implementation relies on the REST-based ELK stack (Elasticsearch, Logstash, Kibana), which has become established during the performant and distributed monitoring of system logs.
We have extended the technological basis with the possibility to administer test reports with different administration and UI clients. In addition, the individual components were decoupled by various Docker containers with template-based configuration files (Jinja2) as well as provisioning tools (Ansible, Puppet).
We have consistently focused on test-driven development using CircleCI. The finished overall solution is integrated in the individual, corresponding Jenkins jobs using a dedicated Docker registry as needed. The logstash containers provide the individual test results with environmental data.
In our session, we present our motivation, possible solutions and the implemented solution components, especially in practical interaction within a Continuous Delivery Pipeline.
Let yourself be surprised by the variety of possible uses within a productive context!
20:30 - Applying (D)DDD and CQ(R)S to Cloud Architectures
Many software architectures may benefit from the introduction of (Distributed) Domain-Driven Design and Command Query (Responsibility) Separation. Regardless if you are maintaining large legacy software systems or whether you start a new microservices platform as greenfield approach one always has to think about the domain language and service design.
In this talk Benjamin will show you a given example of 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 talk consists of several steps / iterations each with a small lecture a dedicated implementation goal that will be solved. At the end one will be able to apply many DDD principles and will have learned how to tailor systems according to their domain – effectively and efficiently while using modern technology standards.
Benjamin recently joined the forces at codecentric AG with a long-term hands-on experience with introducing, building, coaching and speaking about Java, Testing, Microservices, Docker and disruptive technologies (especially in the e-commerce sector).
He is a leader and founder of Thuringia JUG in Germany, a board member at the Java Aktuell magazine and at the microXchg conference as well as the JavaLand conference — offering over 100 sessions for more than 2000 visitors each year.
Besides the Java ecosystem he also founded and runs a local software craftsmanship community and a Devoxx4Kids community – totalling over 40 events in the past 3 years including quite a few full-day workshops, code retreats and hackathons. Regularly he also gives university lectures on OOP, Java, containers, Git, Project Management and Agile Methodologies.
In his leisure time he enjoys road cycling, art and theaters, wine/gin/whiskey tastings and discussions about politics and improving IT organizations.
