Thursday, November 4, 2021 - 00:00 by Hailley Seed

Jakarta EE ended 2020 with the major Jakarta EE 9 release in December and has now approved the Jakarta EE 10 release plan. With all the changes happening in Jakarta EE be sure to check out these 3 talks to learn more about upcoming features and improvements at the JakartaOne Livestream 2021. Some of the talks include:


7 Reasons to Switch to JDK 17 as a Jakarta EE Developer

Speaker: Rudy De Busscher

JDK 17, the next LTS version of Java, is around the corner, this session will explore what a Jakarta EE developer will find interesting including new language constructs and many operational improvements such as higher performance.

Learn about these features and improvements including Records, Text blocks, Garbage collection improvements, and monitoring through Flight Recorder in several live demos. Learn more.

Running Jakarta EE Applications inside Kubernetes with Nested Container Architecture

Speaker: Ruslan Synytsky

Kubernetes enables possibilities to develop cloud native microservices or decompose traditional applications making them more technologically advanced with the help of containers. Currently, most of the Kubernetes solutions are offered on top of VMs and there is room for further improvements. Implementing nested architecture of application containers running inside system containers opens up  additional flexibility of resource allocation and management, accelerates provisioning of the clusters and pods, as well as cuts the overall costs. This session will review the possibilities of running a Jakarta EE application inside Kubernetes cluster with nested container architecture, what configurations should be taken into account, and how to overcome the barriers on the way to more efficient Kubernetes hosting. Learn more.


Integration Testing of Jakarta EE Applications with Docker and Testcontainers

Speaker: Kevin Wittek 

Without proper integration testing such databases and other services, you might not know how your application will actually behave once it has been deployed to the real production environment. Before Docker, configuring the environment for integration testing was strenuous. However, thanks to Docker, now we can quickly prepare the environment for our tests. This session will explore how you can use Testcontainers,  a popular Java testing library that provides lightweight, throwaway instances of common databases, Selenium web browsers, or anything else that can run in a Docker container.  

Come and learn why Apache, Spring, ZeroTurnaround, JetBrains, Playtika, Zipkin, and others already decided to use Testcontainers for their integration testing needs! Learn more.
