Track: Java - Propelling the Ecosystem Forward

Day of week:

Java continues to evolve to support an ever-changing ecosystem of applications, languages, and platforms. Whether you are building systems that run at scale, or applications for mobile devices, performance and features are key. This track will focus on how you can build better software, innovate in new spaces, and improve efficiency by leveraging improvements in the JDK.

Track Host:
Haley Tucker
Senior Software Engineer, Playback Features @Netflix
Haley Tucker works on the Playback Features team at Netflix, responsible for ensuring that customers receive the best possible viewing experience every time they click play. Her services fill a key role in enabling Netflix to stream amazing content to 65M+ members on 1000+ devices. Prior to Netflix, Haley spent a few years building near-real-time command and control systems for Raytheon. She then moved into a consulting role where she built custom billing and payment solutions for cloud and telephony service providers by integrating Java applications with Oracle platforms. Haley enjoys applying new technologies to develop robust and maintainable systems and the scale at Netflix has been a unique and exciting challenge. Haley received a BS in Computer Science from Texas A&M University.

Spring Framework Committer @Pivotal

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...

Cloud Technology Consultant with an expertise in Serverless Computing

The modern Java Virtual Machine (JVM) is the culmination of millions of hours of expert engineering, and is the foundation on which enormous portions of the digital landscape are built. However, as a runtime for AWS Lambda functions, the JVM is often derided as being a poor fit for an ephemeral world. The truth of the matter is that the JVM is an excellent choice of runtime for a wide range of AWS Lambda use cases, and developers need not even constrain themselves to just the Java language...

CSO @Speedment

Migrating a Java 8 application to Java 9 is not just an exercise in API management, but also a learning experience in areas such as memory management and package dependencies.

This talk will share insights from our experience migrating Speedment to Java 9 with a focus on 2 key areas. First, Speedment is an ORM with a Java 8 Streams API and one of its prominent features is acceleration based on in-memory off-heap caching of data. Because it relies on the efficient handling of Strings...

Graal Compiler Architect

Current language runtimes often execute in isolation -- running in different processes, using different compilation infrastructure, and maintaining their own garbage collectors. There is no reuse of infrastructure and cross-language communication is inefficient. Our vision of the future of execution runtimes is Graal: an integrated, polyglot, high-performance execution environment. Its core is a new just-in-time compiler for the Java Virtual Machine. Graal doesn’t only support Java-based...
