Adopting Java for the Serverless world

" summary

Claims that GraalVM native images cut cold starts to under <0.5s cold starts and shrink memory by excluding unused classes, but building a native image takes about 3.5 minutes for a simple function and requires a Linux executable and a custom runtime (extra overhead). Micronaut and Quarkus trade reflection for AOT-friendliness so they speed cold starts even without GraalVM; Quarkus offers a Maven native-image plugin while Micronaut currently lacks one for Maven, and Spring is still catching up via Spring Native with extra boilerplate.
