Going Serverless With Spring’s Support for GraalVM, Project CraC & More

on YouTube ↗41m

" summary

Compares concrete results: a baseline Spring Boot app cold-starts in ~6.5 seconds and uses ~200 MB; a GraalVM native image cuts startup to ~400 ms and roughly quarters memory but native builds take ~3m30s and ~3.5 GB RAM so CI-based builds are recommended; Project CraC restores a warmed JVM to ~244 ms startup with no memory win and requires snapshot handling and extra OS capabilities; class data sharing gives smaller, safe 2–4× startup wins with a single flag and minimal trade-offs.
