Serverless Java in Action with Fn!

on YouTube ↗56m

" summary

Demo uses the open source Fn FaaS platform with the Java FDK and Fn CLI to build containerized functions via Docker, deploy locally or to Oracle Cloud, and run Maven builds and JUnit blackbox tests. Cold start drops from ~1s+ to <100 ms on a hot local container; remote invocations hit ~600–1000 ms. Orchestration uses the Fn Flow API to compose parallel calls with retries and partial failures, example generating up to seven destinations. Image sizes: Java 8 full GRE ~269 MB, jlink stripped runtime ~40 MB, GraalVM native-image binary ~22 MB.
