Explore the innovative OpenJDK project CRaC (Coordinated Restore at Checkpoint) in this informative conference talk from GeeCON 2022. Delve into the challenges of JVM warmup time in microservices architecture and cloud-based Java applications. Learn how CRaC aims to address these issues by introducing a novel approach: taking snapshots of running JVMs and restoring them later or on different machines. Compare this method to native images, understanding their advantages and limitations in startup time and overall performance. Gain insights into the proof of concept implementation and its results, showcasing the potential of CRaC to revolutionize JVM startup speeds in cloud environments.
