Agenda Day 1

Welcome to Java 9

Jeanne Boyarsky Software Developer, CodeRanch

Coming soon - Java 9 is nearing official release. As Java developers, we should be ready. Java 9 is more than just Jigsaw and we will look at some of the still useful but less talked about features. Some will save you typing and make your code easier to read such as changes to try-with-resources and inner classes. Some are new APIs that will save you time like new stream APIs. Attendees will walk away knowing what’s new and improved in Java 9 regardless of whether they need to complete a jigsaw puzzle.

Live Coding with Spring Boot & Actuators

John Humphreys VP of Engineering Infrastructure Systems, Nomura

Spring Boot is a modern and extensible development framework that aims (and succeeds!) to take as much pain as possible out of developing with Java. With just a few Maven dependencies, new or existing programs become runnable, init.d-compliant uber-JARs or uber-WARs with embedded web-servers and virtually zero-configuration, code or otherwise. As an added freebie, Spring Boot Actuator will provide your programs with amazing configuration-free production monitoring facilities that let you have RESTFUL endpoints serving live stack-traces, heap and GC statistics, database statuses, spring-bean definitions, and password-masked configuration file audits.

Microservices Pattern Language

Chris Richardson Founder, Eventuate

When architecting an enterprise Java application, you need to choose between the traditional monolithic architecture consisting of a single large WAR file, or the more fashionable microservices architecture consisting of many smaller services. But rather than blindly picking the familiar or the fashionable, it’s important to remember what Fred Books said almost 30 years ago: there are no silver bullets in software. Every architectural decision has both benefits and drawbacks. Whether the benefits of one approach outweigh the drawbacks greatly depends upon the context of your particular project. Moreover, even if you adopt the microservices architecture, you must still make numerous other design decisions, each with their own trade-offs. A software pattern is an ideal way of describing a solution to a problem in a given context along with its tradeoffs. In this presentation, we describe a pattern language for microservices. You will learn about patterns that will help you decide when and how to use microservices vs. a monolithic architecture. We will also describe patterns that solve various problems in a microservice architecture including inter-service communication, service registration and service discovery.

Servlet vs Reactive Stacks in 5 Use Cases

Rossen Stoyanchev Spring Framework Developer

In the past year Netflix shared a story about upgrading their main gateway serving 83 million users from Servlet-stack Zuul 1 to an async and non-blocking Netty-based Zuul 2. The results were interesting and nuanced with some major benefits as well as some trade-offs. Can mere mortal web applications make this journey and moreover should they? The best way to explore the answer is through a specific use case. In this talk we'll take 5 common use cases in web application development and explore the impact of building on Servlet and Reactive web application stacks. For reactive programming we'll use RxJava and Reactor. For the web stack we'll pit Spring MVC vs Spring WebFlux (new in Spring Framework 5.0) allowing us to move easily between the Servlet and Reactive worlds and drawing a meaningful, apples-to-apples comparison. Spring knowledge is not required and not assumed for this session.

Reactive Programming by Example

Victor Grazi VP, Nomura

Reactive Programming is an emerging paradigm for non-blocking concurrent programming. This means you can have multiple workers without allocating resources to multiple threads! In this presentation we will take a look at what reactive programming is and why it has become so popular. Then we will look at Pivotal's Reactor implementation, along with a deep dive into some coding examples.

Agenda Day 2

Advanced Spring Boot & Consul

Michael Gendelman Systems Management Architect, Nomura

Take your Spring Boot applications to the next level by utilizing configuration service, discovery service and advanced metrics and monitoring, needed to support micro services and cloud. We will add discovery and configuration services to an existing Spring Boot application and demonstrate hot configuration change and failover. We will create custom metrics and push them out to a common monitoring framework.

Cloud-Native Streaming and Event-Driven Microservices

Marius Bogoevici Spring Cloud Stream Lead

Join us for an introduction to Spring Cloud Stream, a framework for creating event-driven microservices that builds on on the ease of development and execution of Spring Boot, the cloud-native capabilities of Spring Cloud, and the message-driven programming model of Spring Integration. See how Spring Cloud Stream’s abstractions and opinionated primitives allow you to easily build applications that can interchangeably use RabbitMQ, Kafka or Google PubSub without changing the application logic. Finally, we will show how these applications can be orchestrated and deployed on different modern runtimes such as Cloud Foundry, Kubernetes or Mesos using Spring Cloud Data Flow.

Test Driven Development for Microservices Architectures

Reshmi Krishna Senior Cloud Application & Platform Architect, Pivotal
Vinay Upadhya Advisory Platform Architect, Pivotal

TDD introduced many improvements into the development process with the biggest advantage relating to code design. As we move to a microservices based architecture, TDD becomes hard to implement across teams building different codebases. Consumer driven contracts (CDC) is like TDD but applied at the API level and is becoming more relevant in the world of microservices. It is a pattern for specifying and verifying interactions between different modules of an application. Spring Cloud Contract provides support for Consumer Driven Contracts and service schemas in Spring applications, covering a range of options for writing tests, publishing them as assets, asserting that a contract is kept by producers and consumers, for HTTP and message-based interactions. In this session, you will learn how we can implement TDD in microservices based architecture using Spring Cloud Contracts.

JHipster 4: Bringing Together Angular and Spring Boot

Yakov Fain Solutions Architect, Farata Systems

JHipster 4 is an open-source code generator that allows you to automate creation and configuration of a Web project that uses the Angular framework on the front and Spring Boot on the back. We'll start with a simple example where an Angular app consumes the REST service from Spring Boot. After that, we'll use JHipster to generate a complete Angular/Spring Boot project.

Automated Testing for Digital Experiences Using JUnit 5

Justin Baumgartner Solstice

JUnit 5 is launching this fall and will undoubtedly move the needle for automated testing. Simultaneously, the demands of digital continue to grow and place a greater importance on automated testing for backend systems. Join Justin Baumgartner for a discussion where he will highlight the new features of JUnit 5, including Lambda support, dynamic and parameterized tests, and advances in integration testing. Justin will demonstrate the new testing features through the lens of a conversational UX experience.
