Are you running into problems with Java applications in production? Not understanding what is eating up all your system resources? And throwing a bunch of System.out messages in your code is not helping? You should check out the JDK Flight Recorder (JFR). JFR is a powerful and low-overhead observability tool built into the JVM that can help you track down those performance issues and difficult-to-understand bugs. In this presentation, we will go through the basics of using JFR in your Java applications.

In a world where our applications are mission-critical and our users expect near instant responses, application startup time is crucial. What we need is a way of containerizing our applications to start up in milliseconds, but importantly, without compromise and with little or no refactoring of our code. The exciting news is - this is now possible! With Spring Boot 3 and Liberty InstantOn, Spring-based applications can now be deployed to the cloud with CRaCing startup times, enabling scale-to-zero without causing high latency when new instances are started. Interested in learning how? Join this session to learn more about these innovative technologies and how you can make use of them in your own Spring Boot and Jakarta EE applications.
