Efficient containers with Spring Boot 3 and Java 21

Sébastien Deleuze - Broadcom

Spring Boot 3 brings runtime efficiency and performance related enhancements in order to ease the deployment of your Spring Boot applications deployed as containers on production.

In this presentation, Sébastien will share an overview on how to migrate Spring Boot 2 applications running on Java 8 to Spring Boot 3 running on Java 21, and how to leverage builtin support for technologies like Virtual Threads, Spring Ahead-Of-Time optimisations, CDS and Buildpacks to run them faster and more efficiently on the JVM.

Sébastien will also compare data points for various types of instances (CPU, memory), runtime (Java 8, 17, 21, GraalVM native images) and technologies (including a preview of Project Leyden optimisations) in order to allow you to do the right choices for your context and your use cases.
