Monolith to Serverless - Can Modern Cloud-Native Java Runtimes Do It All
summary
Compares concrete runtimes and fixes: shows Open Liberty running Spring Boot and microservices with an OpenJ9 JVM offering ~51% faster startup and ~50% smaller memory, and demos a JIT offload “compiler server” that cuts CPU spikes across three AcmeAir instances; explains CRIU-based instant-on checkpoint/restore that drops a 5s start to ~310ms; shows Knative scale-to-zero compatibility and a cloud AOT pipeline, with benchmarks and Kubernetes configs so developers can judge tradeoffs.
