Mandrel: A specialized distribution of GraalVM for Quarkus

By Severin Gehwolf April 14, 2021April 12, 2021

When we first announced Mandrel, we explained why Red Hat needed a downstream distribution of GraalVM. We were most interested in GraalVM’s native image capability, specifically in the context of Quarkus. In this article, we explain what Mandrel is and what it’s not. We’ll introduce some of Mandrel’s technical features and offer a short demonstration of using Mandrel with Quarkus.

Build even faster Quarkus applications with fast-jar

By Daniel Oh April 8, 2021April 6, 2021

Quarkus is already fast, but what if you could make inner loop development with the supersonic, subatomic Java framework even faster? Quarkus 1.5 introduced fast-jar, a new packaging format that supports faster startup times. Starting in Quarkus 1.12, this great feature became the default packaging format for Quarkus applications. This article introduces you to the fast-jar format and how it works.

Enhancing the development loop with Quarkus remote development

By Daniel Oh February 11, 2021February 9, 2021

Kubernetes is an established foundation layer for cloud-native microservices and serverless architectures. By automating application deployment, scaling, and management, Kubernetes changes the developer’s daily workflow in terms of inner loop development (local coding, building, running, and testing the application) and outer loop development (integration testing, continuous deployment, and security). Developers using Kubernetes also must plan for containerization, debugging code inside pods, and automating test cases.

Spring Boot on Quarkus: Magic or madness?

By Eric Deandrea February 9, 2021February 17, 2021

Quarkus is a Java stack tailored for OpenJDK HotSpot (or OpenJ9 on zSeries) and GraalVM, crafted from optimized Java libraries and standards. It is a good choice for building highly-scalable applications while using lower amounts of CPU and memory resources than other Java frameworks. These applications can be traditional web applications, serverless applications, or even functions as a service.

Write a Quarkus function in two steps on Red Hat OpenShift Serverless

By Daniel Oh January 29, 2021February 4, 2021

Serverless functions are driving the fast adoption of DevApps development and deployment practices today. To successfully adopt serverless functions, developers must understand how serverless capabilities are specified using a combination of cloud computing, data infrastructure, and function-oriented programming. We also need to consider resource optimization (memory and CPU) and high-performance boot and first-response times in both development and production environments. What if we didn’t have to worry about all of that?

Create your first serverless function with Red Hat OpenShift Serverless Functions

By Naina Singh January 4, 2021January 4, 2021

Serverless is a powerful and popular paradigm where you don’t have to worry about managing and maintaining your application infrastructure. In the serverless context, a function is a single-purpose piece of code created by the developer but run and monitored by the managed infrastructure. A serverless function’s value is its simplicity and swiftness, which can entice even those who don’t consider themselves developers.
