MicroProfile, Jakarta EE, Open Liberty, and Java at EclipseCon 2021

Open J9’s Vijay Sundaresan and Mark Stoodley will review these latest innovation available to Java users, including Virtual Machine technologies (e.g., in Eclipse OpenJ9) to optimize Java workloads for containers and cloud. They’ll delve into how these innovations benefit cloud-native runtimes (e.g., Open Liberty), and discuss how you can adopt them to optimize your cloud-native Java application and microservice deployments for performance (e.g., fast startup and throughput), efficiency (e.g., memory footprint and consumption) and hence, cost savings.

Graham Charters will team up with Microsoft’s Principal Architect Edward Burns to lead this fast-paced hands-on workshop, where you’ll see first-hand how to run Java EE, Jakarta EE, and MicroProfile applications on Open Liberty on Azure Red Hat OpenShift (ARO). The combination of ARO with Open Liberty offers a powerful and flexible platform for your enterprise Java applications.

Open Source has become the de facto way to build software. So, how and what are we doing in enabling the next-generation of up-and-coming developers to participate in open-source software development? Join Open Liberty’s YK Chang and Kathryn Kodama, with Karim Ali and Jeff Cho, as they take a look at the Canada Open-Source Projects (CANOSP) program. They will explore the program’s experience and successes, and what they have learned from advocating for open source and equipping university and college students to participate in open-source software development

Thomas Watson will discuss a different approach to achieve "Instant On" for Java applications using Checkpoint/Restore in Userspace (CRIU). CRIU is a Linux feature that takes a snapshot of a running application. This snapshot can then be restored very quickly from the point the snapshot was taken and resume serving the application users. This session will alo include a demo of using this approach with OpenJ9 and Open Liberty in a (Docker) container image.

Java Champion Emily Jiang will discuss how MicroProfile has evolved to become a standard body for developing cloud-native APIs. She’ll bring you up to date with the new features in MicroProfile 4.0 with a live demo and briefly discuss what is next for this open source project. Come to this session to get yourself updated with the latest news on MicroProfile.

Grace Jansen introduces the concept of test containers within this session and delves into why utilising containers to test our cloud-native applications can enable us to ensure our tests are replicating our production environment as closely as possible. She’ll demo live how Testcontainers can help you run and test with true-to-production environments in development with minimal re-writing of your test code.

In this session, Open Liberty’s Andrew McCright and Adam Anderson will discuss and demo how you can rapidly build data-driven microservices using MicroProfile GraphQL - a tool that makes it simple to create Java-based GraphQL services with a few annotations. This session will demonstrate the power and simplicity of making a relational database accessible as a service or cloud-native environment.
