6:15-7:45: Project Jigsaw in JDK 9: Modularity Comes To Java

Project Jigsaw will bring modularity to the Java platform; something that will enable better security, performance and flexibility for deployment of applications. This talk will look at the fundamentals of how modularity in Java will work. Developers will need to understand that these changes go significantly further than just separating the standard class libraries into a number of discrete units.

This talk will explain the impact project Jigsaw will have on developers in terms of building their applications, as well as helping them to understand how things like encapsulation of private APIs, which have up until now been visible, will change in JDK 9.

6:15-7:45: Reactive Programming on the Server

Reactive streams is an initiative to provide a standard for asynchronous stream processing with non-blocking back pressure. Reactive programming is a hot topic these days. It has been the go to strategy for client applications for a while however it is slowly making its was in to the back end server stack. Spring 5 and Java 9 will introduce Reactive Streams and their implementation. This talk will explore the 4 interfaces that make up the solution and look at some real world applications and examples.

6:15-7:45: Microservices with Kubernetes – Ray Tsang

Learn how to create a Java-based microservice using Spring Boot, containerize it using Maven plugins, and subsequently deploy a fleet of microservices onto a cluster of machines using Kubernetes.

Running a single microservice is fast and easy. Like most Java applications, the harder part is usually the clustering and fail-over configurations.

First, we’ll create a microservice using Spring Boot, and, subsequently, generate and create Docker images during the build process, and finally we’ll deploy the microservice into Kubernetes:

– Defining pods and services

– Perform rolling upgrades of the application

– Canary new versions of the microservices into the fleet

– Linking microservices to Redis using Kubernetes

– Configure Health Check and Readiness Checks

– Managing configurations via arguments, environmental variables, and ConfigMap

The best part is we can visualize all these activities happening in Kubernetes.

About Ray Tsang:

Ray is a Developer Advocate for the Google Cloud Platform. Ray had extensive hands on cross-industry enterprise systems integration delivery and management experiences during his time at Accenture, managed full stack application development, DevOps, and ITOps. Ray specialized in middleware, big data, and PaaS products during his time at Red Hat while contributing to open source projects, such as Infinispan.
