Red Hat Developer has published Quarkus for Spring Developers, a comprehensive, 149-page e-book introducing Quarkus to Java developers, with a focus on helping people familiar with Spring make the transition. This includes the Spring Framework and Spring Boot, and any other modules within the Spring ecosystem.
While Java continues to be one of the most widely used programming languages for building applications, Java developers often struggle to make their applications smaller and faster to meet modern computing requirements.
Quarkus is designed to help.
What is Quarkus?
Introduced by Red Hat, Quarkus is an open source project that is designed to work with popular Java standards, frameworks and libraries, including Spring.
It’s a full-stack Kubernetes-native Java framework made for Java virtual machines (JVMs) and native compilation, optimizing Java specifically for containers so it can be used in serverless, cloud and Kubernetes environments.
What’s in the e-book?
In this book you’ll learn:
How to optimize Java for modern compute and runtime demands.
The history of Quarkus and the challenges that led to its creation.
How Spring conventions are implemented in Quarkus through like-for-like examples, including testing.
How Quarkus can increase developer productivity cycles through live coding, developer services and continuous testing.
With a plethora of examples, comparisons and code samples, this book will help you get up to speed on developing containerized applications with Quarkus.
All source code from the book is available on GitHub, and the book includes the following chapters.
Chapter 1: Introducing Quarkus
The e-book opens with a brief history of and introduction to Java, Spring, microservices, and Quarkus. Sections include:
Brief history of Java
Introduction of Spring
Emergence of microservices
Challenges of microservices

Testing server-sent event endpoints
Chapter 4: Persistence
Again highlighting the differences between Quarkus and Spring, this chapter digs into an application’s persistence layer, including:
Chapter 5: Event-Driven Services
Here, the book goes over the benefits of Quarkus for implementing event-driven services using publish-subscribe events, reactive streams with Kafka, and Knative events, including:
Chapter 6: Building Applications for the Cloud
The final chapter covers building applications for the cloud, including:
