Devnexus 2022 - Java on CRaC Superfast JVM Application Startup - Simon Ritter, Gerrit Grunwald

This talk explores the challenges and potential solutions associated with optimizing startup and warmup times in JVM-based microservices through the use of the CRaC project, which stands for Coordinated Restore at Checkpoint. The speaker discusses the traditional issues posed by JIT compilation and the alternative of using native images, which come with trade-offs in performance. By examining a proof-of-concept implementation, the session highlights how checkpointing techniques could facilitate quicker restoration of Java applications, ultimately enhancing responsiveness in a microservice architecture. The speaker, Simon Ritter, has a long-standing background in Java from his time at Sun Microsystems to his current role at Azul Systems.
