Build resilient and scalable, cloud native, enterprise Java applications using the Quarkus framework.

In Quarkus in Action, you will:

• Use Quarkus Dev mode to speed up and enhance Java development
• Understand how to use the Dev UI to observe and troubleshoot running applications
• Automatic background testing using the Continuous Testing feature
• New frameworks and libraries such as Reactive Messaging, gRPC, and GraphQL
• Simplify deployment of applications into Kubernetes and OpenShift
• Automatic management of remote services such as databases and message brokers

Quarkus in Action teaches you to build resilient and scalable cloud applications with Quarkus. It's written by Martin Štefanko and Jan Martiška, Red Hat engineers who are both active contributors to the Quarkus project. Working hands-on through a realistic business application, you'll use Quarkus to simplify the development process of a car rental application. Learn how Quarkus lets you live-reload your Java code, deliver continuous background testing, and automatically provide database instances, as well as offering tons more productivity-boosting features.
