Pragmatic App Migration to the Cloud: Quarkus, Kotlin, Hazelcast, GraalVM in action
summary
A simple URL shortener is implemented with Kotlin + JAX-RS backed by Hazelcast MDG, then compiled to a native executable with Quarkus + GraalVM. The demo shows curl-created short links stored and retrieved successfully, the native Docker image starts far faster and uses less memory than the JVM build, but AOT compilation takes long, reflection needs manual config, and platform-specific binaries are required. The recommended path reuses existing code rather than full rewrite.
