Ray Tsang

Dependency conflicts come in many different forms and have different impacts on your applications. This presentation examines common causes of a dependency conflict, how you can mitigate it as a library developer, and how end users can resolve it. Java Champions Ray Tsang and Robert Scholte will share their knowledge, Ray (developers advocate for Google) from the user perspective and Robert (chairman Apache Maven) from the Maven perspective. Join this session to see common issues Ray has observed from working with customers, and Robert’s advise on how to detect issues early. It also covers what Google has been documenting in terms of best practices and what tools it has created to help, based on its learnings.

Ray has been on a 6-months rotation with an internal Google team to help bringing a project to public Cloud using cloud-native technology stack and Kubernetes. Ray will share the architecture, development environment technicals, devops tools, and some tough decisions that needed to be made to move the project along while being prepared for changes in the future. This session to learn the journey including development environment tools choices (Docker Compose, Skaffold, Kustomize, Jib), to the stack (Gradle, Spring Boot, Kafka, PostgreSQL, gRPC, gRPC-Web), to mono-repo vs multi-repo, to the runtime infrastructure (Kubernetes, Istio, Prometheus, Grafana). With hindsight 20-20, we’ll visit some best practices, lessons learned, and how decisions/compromises are being made.
