Workshop: GraalVM (part 2)

on YouTube ↗01h 14m

" summary

Hands‑on demo builds a GraalVM native-image from a Micronaut web app, runs it in Docker and shows concrete numbers: a compressed executable boots startup under 100ms, putting a statically linked binary into a distroless container yields ~96 MB image with a 77 MB app (distroless image 96MB with 77MB app), fully static musl binaries can run from scratch, -Xmx limits contain memory (unconstrained runs hit ~800 MB), and PGO boosts throughput by roughly 50% in the demo. Observability requires app-side metrics (Micrometer) because JVMTI/JMX remote tooling is limited.
