The Future of Serverless Java

on YouTube ↗30m

" summary

Java currently powers ~12 million developers and ~80% of enterprises yet only ~5% of serverless functions use it; the gap narrows by concrete changes: class data sharing (application CDS on by default in Java 12) and jlink cut runtime sizes to ~30MB, GraalVM’s native-image provides AOT binaries for millisecond cold starts at the cost of some reflection, and the six‑month JDK cadence plus Panama and Project Portola improve container and native interop. Cloud support lags (AWS Lambda defaults to Java 8).
