Red Hat build of Quarkus: Kubernetes-native Java

Kubernetes-native Java with low memory footprint and fast boot times for microservices and serverless applications.  Explore all Java content. 

Red Hat build of Quarkus 3.8 is now available. Click here for more details.


Quarkus is a Kubernetes-native Java stack for microservices and serverless development due to its fast startup times, low memory footprint, and small application size.

Creating applications for the hybrid cloud can be a challenge. Developers need to handle data persistence, integrate disparate services, ensure application security, and much more. An orchestrated development environment accelerates the creation and deployment of applications across both public and private clouds allowing developers to build once and deploy anywhere.

Quarkus is an ideal Java framework for the hybrid cloud because of its ability to support both traditional and cloud-native architectures. Quarkus is designed to optimize Java for container environments, and as a result, can significantly increase developer productivity and reduce operational costs.

Quarkus for Spring Developers

Quarkus for Spring Developers is a Spring developer's ultimate resource to learn about Quarkus and Kubernetes-native Java. It showcases and explains how Quarkus enables modern Java development and the Kubernetes-native experience. Get introductions to familiar Spring concepts, constructs, and conventions through equivalent code examples, then learn how they map to Quarkus. It additionally places emphasis on testing patterns and practices. This talk explains what led to the writing of the book in the first place while also highlighting some of the similarities and differences of Quarkus and Spring.
