Kubernetes Native Microservices with Quarkus and MicroProfile

Build fast, efficient Kubernetes-based Java applications using the Quarkus framework, MicroProfile, and Java standards.

In Kubernetes Native Microservices with Quarkus and MicroProfile you’ll learn how to:

Deploy enterprise Java applications on Kubernetes

Develop applications using the Quarkus runtime

Compile natively using GraalVM for blazing speed

Create efficient microservices applications

Take advantage of MicroProfile specifications

Popular Java frameworks like Spring were designed long before Kubernetes and the microservices revolution. Kubernetes Native Microservices with Quarkus and MicroProfile introduces next generation tools that have been cloud-native and Kubernetes-aware right from the beginning. Written by veteran Java developers John Clingan and Ken Finnigan, this book shares expert insight into Quarkus and MicroProfile directly from contributors at Red Hat. You’ll learn how to utilize these modern tools to create efficient enterprise Java applications that are easy to deploy, maintain, and expand.

About the technology

Build microservices efficiently with modern Kubernetes-first tools! Quarkus works naturally with containers and Kubernetes, radically simplifying the development and deployment of microservices. This powerful framework minimizes startup time and memory use, accelerating performance and reducing hosting cost. And because it's Java from the ground up, it integrates seamlessly with your existing JVM codebase.

About the book

Kubernetes Native Microservices with Quarkus and MicroProfile teaches you to build microservices using containers, Kubernetes, and the Quarkus framework. You'll immediately start developing a deployable application using Quarkus and the MicroProfile APIs. Then, you'll explore the startup and runtime gains Quarkus delivers out of the box and also learn how to supercharge performance by compiling natively using GraalVM. Along the way, you'll see how to integrate a Quarkus application with Spring and pick up pro tips for monitoring and managing your microservices.
