Microservices with Kubernetes, Docker, and Jenkins (Rafael Benevides, Christian Posta)

A lot of functionality necessary for running in a microservices architecture have been built into Kubernetes; why would you re-invent the wheel with lots of complicated client-side libraries? Have you ever asked why you should use containers and what are the benefits for your application? This talk will present a microservices application that have been built using different Java platforms: WildFly Swarm and Eclipse Vert.x. Then we will deploy this application in a Kubernetes cluster to present the advantages of containers for MSA (Microservices Architectures) and DevOps. The attendees will learn how to create, edit, build, deploy Java Microservices, and also how to perform service discovery, rolling updates, persistent volumes and much more. Finally we will fix a bug and see how a CI/CD Pipeline automates the process and reduces the deployment time.

Refactoring your Code with Java 8 Functional Programming to the Rescue

In this talk, we'll show how you can refactor your traditional object-oriented Java code using Functional Programming features and APIs from Java 8, following several recipes and refactor legacy code in order to make it more readable and flexible. We discuss: - How to separate concerns using Lambda Expressions - How to handle with requirement changes using first-class functions - How to make several traditional OO design patterns more concise using lambda expressions The talk will consist of a balance between theoretical concepts and practical applications. Attendees will leave with concrete knowledge to refactor their traditional object-oriented Java code to make the best use of Functional Programming features and new APIs Java 8 APIs.

Dockerized System Testing, with a Dash of Chaos (Aslak Knutsen, Bartosz Majsak)

With microservices, polyglot, and DevOps on the rise, where are we at with testing? Does it bring more complexity and make our testing effort harder? Or maybe, on the contrary, it actually helps us write better tests more easily? This session explores not only how we can do our testing in this new world but also how the new world can help us test better. Meet Arquillian Cube and Q. The presentation takes a close look at topics ranging from polyglot services and orchestrated microservices to system scale testing. All are within reach. And with full control, let’s add a dash of chaos!

Kubernetes for Java Developers (Edson Yanaga, Rafael Benevides)

Yes, Docker is great. We are all very aware of that, but now it’s time to take the next step: wrapping it all and deploying to a production environment. For this scenario, we need something more. For that “more,” we have Kubernetes by Google, a container platform based on the same technology used to deploy billions of containers per month on Google’s infrastructure. Ready to leverage your Docker skills and package your current Java app (WAR, EAR, or JAR)? Come to this session to see how your current Docker skill set can be easily mapped to Kubernetes concepts and commands. And get ready to deploy your containers in production.
