Prerequisite knowledge

  • An intermediate understanding of Kubernetes and containers

What you'll learn

  • Learn how to migrate a monolithic Java application to running in Kubernetes

Description

Writing monolithic Java applications has long been a standard for enterprise engineering shops. Kris Nova leads a deep dive into the world of migrating a monolithic Java application to Kubernetes, using a prototype Java application that has been designed to be hard to run cloud natively as an example.

Kris starts by containerizing the application and exploring the nuances of the JVM in a Docker container and demonstrates that the entry point of the application is not conducive to breaking it apart into microservices. You’ll explore the code and discover how to start decoupling the application based on new entry points; you’ll also connect Java native systems logging to Prometheus and connect the application health checks to Kubernetes primitives. Kris finishes the demonstration by mapping out the full application into Kubernetes primitives and making a legacy Jenkins build pipeline manage the CI/CD. Join in to learn cloud-native philosophy in ways familiar to the Java ecosystem and see how to overcome common bottlenecks in migrating Java applications to Kubernetes.
