CRaCing Java Snapshots
Session en Anglais - Débutant
Java apps start slow — JIT warmup, framework init, connection pools. What if your app could resume from a running snapshot in milliseconds? This talk shows CRaC (Coordinated Restore at Checkpoint): checkpoint a live JVM to disk, restore it near-instantly. We start from CRIU, see why it fails on Java, then CRaC it for real — plain Java and Spring Boot, in Docker. Live demos, real caveats, and how to handle app state across a checkpoint.
Crafting the Ultimate Docker Image for Spring Applications
Session en Anglais - Intermédiaire
Your Spring Boot app is 1 MB, but its image is 713 MB, and 590 MB of that changes on every build. Live, we will shrink it step by step: multi-stage builds, layered jars, buildpacks, jlink and distroless. Then we move from size to speed and use AppCDS, AOT and CRaC to take startup from seconds to milliseconds. Each step comes with measured numbers and an honest price tag, so you can choose which kind of ultimate your image needs.
