You can find the sources in the following GitHub repository: Under the hood, this demo uses RESTEasy to expose the REST endpoints.

This is a minimal CRUD service exposing a couple of endpoints over REST. To demonstrate this approach I use a demo application based on GraalVm is developed by Oracle and has capability to run JVM based language natively (by compiling Java bytecode to machine code) and supports other languages like JavaScript,Python, Ruby ,C,C++ ,R etc. It can run either standalone or in the context of OpenJDK, Node.js or Oracle Database. GraalVM removes the isolation between programming languages and enables interoperability in a shared runtime. GraalVM is a universal virtual machine for running applications written in JavaScript, Python, Ruby, R, JVM-based languages like Java, Scala, Groovy, Kotlin, Clojure, and LLVM-based languages such as C and C++.

Simple and unified configuration (see ).

Support imperative and reactive code or a mix of both (see ).

Use best of breed Java libraries and standard: Eclipse MicroProfile, CDI, JAX-RS, JPA, Vert.x, Apache Camel, kafka, Vault.

Can be compiled into native code with GraalVM.

Very fast to start and stop, included the first response time.

Quarkus is a framework developed by RedHat which was designed for the container world and which has the following characteristics: Quarkus ?Ī Kubernetes Native Java stack tailored for OpenJDK HotSpot and GraalVM, crafted from the best of breed Java libraries and standards. In this blog post, I show you how Quarkus can run a Java application natively (by compiling Java bytecode to machine code with GraalVM) inside Docker using the most minimal image (and most secure) in Docker “FROM SCRATCH” and deploying it on kubernetes.
