Serverless Java: Challenges and Triumph

on YouTube ↗46m

" summary

Shows concrete tooling and numbers: Java runs on the Fn project with a Java FDK, Maven-based build images and local Docker server, JUnit tests inside containers, and a flow orchestration API modeled on CompletableFuture that composes functions (example Vista: Flickr scraper → plate detector → image annotator → Slack/Twitter) and surfaces failures. Startup improvements use JLink, class-data sharing and Graal/SubstrateVM native images; demo shows a native image ~15 MB vs 400 MB and cold starts dropping from ~1.17s to ~0.79s, and the pipeline works end-to-end.
