Efficient Containers with Spring Boot 3, Java 21 and CDS

Spring Boot 3 brings runtime efficiency and performance related enhancements in order to optimize and reduce the cost of 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 share related data points, demonstrate how Tanzu Platform provides first-class support for those technologies, and provide a glimpse into the future by demonstrating how Project Leyden should allow to speedup even more the startup and warmup of your Spring Boot applications.
