native image

So far, we have looked at how well Spring Boot and Micronaut integrate GraalVM native image extension. In this post, I’ll focus on Quarkus: A Kubernetes Native Java stack tailored for OpenJDK HotSpot and GraalVM, crafted from the best of breed Java libraries and standards. Creating a new project Just as Spring Boot and Micronaut, Quarkus provides options to create new projects: A dedicated quarkus CLIA Web UI Quarkus offers a definite improvement over its competitors. Every

Last week, I wrote a native web app that queried the Marvel API using Spring Boot. This week, I want to do the same with the Micronaut framework. Creating a new project Micronaut offers two options to create a new project: A web UI: As for Spring Initializr, it provides several features: Preview the project before you download itShare the configurationAn API I do like that you can check the impact that the added features have on the POM. A Command-Line Interface: In parallel to the web

The Cloud has enabled a lot of new usages that were not possible before. Among them stands Serverless: Serverless computing is a cloud computing execution model in which the cloud provider allocates machine resources on demand, taking care of the servers on behalf of their customers. Serverless computing does not hold resources in volatile memory; computing is rather done in short bursts with the results persisted to storage. When an app is not in use, there are no computing resources allocat

I’ve been playing with GraalVM AOT compilation capability since I became aware of it. As a long-time Spring aficionado, I carefully monitored the efforts that the engineers at Tanzu have put into making Spring AOT-compatible. Recently, they announced the beta version of the integration. In this post, I want to check how easy it is to produce a (working!) Docker image from an existing Spring Boot application. Introduction GraalVM provides many different features. Among them, the componen

One of my current talks is about creating a Kubernetes operator in Java. I demo it step by step. In the later steps, I’m using GraalVM native image to create a native executable. In that regard, some libraries are not compatible with the native image creation process. Several options are available to make them work anyway. One of the options is to substitute incompatible code with compatible one. In the above post, I describe how to use those substitutions. I thought I had it right. I was
