Quarkus VS SDKMan

Meanwhile, if you're building something smaller than Netflix, I'm writing a book just for that (https://opinionatedlaunch.com/).

It's about mobile apps, but I talk about backend at great length, especially since my background is Java. The book is called "opinionated" because I cover Quarkus (https://quarkus.io/), monolith, Fly.io, and no K8s.

Quarkus is a Java based framework tailored for GraalVM and HotSpot, which results in an amazingly fast boot time while having an incredibly low memory footprint. It offers near instant scale up and high density memory utilization which can be very useful for container orchestration platforms like Kubernetes or Serverless runtimes like AWS Lambda.

Other useful articles related to Quarkus extension development can be found under the Writing Extensions guide category on the Quarkus.io website.

Quarkus is one of Java frameworks for microservices development and cloud-native deployment. It is developed as container-first stack and working with GraalVM and HotSpot virtual machines (VM).

If you GraalVM Native Image or one of the frameworks based on it then bootstrap cost disappears:

We are open to practice using any open-source project, however, we want to set a sharp focus on projects maintained by the Red Hat, and our own projects in the Caravana Cloud organization on github. If there is no reason to do differently, we'll build using technologies such as OpenShift, Quarkus, Ansible and related projects.

The Quarkus you are talking about is this one? https://quarkus.io/

I would suggest learning how to use SDKMAN: https://sdkman.io/

It will manage the JDK for you. Usage is basically this:

   # Install a JDK, that version is now default

Alternatively, you can use sdkman. A great tool to install your Software Development Kit. The downside is that it only works on *nix systems. So for Widnows users, you will have to use WSL or Cygwin as the official page suggests. It is really simple to use sdkman. after a successful installation, just type those commands into your *nix shell:

To run the example, you must install the Auth0 CLI and create an Auth0 account. If you don't have an Auth0 account, sign up for free. I recommend using SDKMAN! to install Java 17+ and HTTPie for making HTTP requests.

Another option for installing Java is SDKMAN!, a versatile tool that’s easy to install and helps you manage multiple versions of Java.

Java 17

Java 17 or higher. You can use SDKMAN! to install Java if you don't have it already.

Ktor, a powerful web framework built with Kotlin, offers a lightweight and flexible solution for building web applications. In this article, we will guide you through the process of creating a Ktor project manually using Gradle and SDKMAN!. By following the steps below, you'll have a basic Ktor project up and running in no time.

If you have any tips/advice then I'm all ears. I've already modified the dnf.conf with fastmirror and max_parallel_downloads I'm currently not using sdkman because this is my personal machine, so I don't mind always using the latest version OpenJDK. If I ever do need to switch between versions then I'll switch over to sdkman instead.

For handling your JDK: I highly recommend purging your system of all JDKs/JRMs - get rid of it all - and download SDK (if you're using Windows, you'll need to do this through WSL). This tool manages software development kits very well; switching between JDKs is super straightforward: sdk use .
