Book Introduction

What distinguishes traditional enterprises from companies like Amazon, Netflix, and Etsy? These companies have perfected cloud-native development methods that enable them to stay ahead and lead the competition. This practical guide shows Java/JVM developers how to build software faster and better using Spring Boot, Spring Cloud, and Cloud Foundry.

Many organizations have already ventured into cloud computing, test-driven development, microservices, and continuous integration and delivery. Authors Josh Long and Kenny Bastani will take you deep into these tools and practices, helping you transform traditional applications into true cloud-native ones.

The book consists of four major parts:

  • Foundation: Understand the motivation behind cloud-native thinking; configure and test Spring Boot applications; migrate your traditional applications to the cloud
  • Microservices: Build HTTP and RESTful services using Spring; route requests in distributed systems; establish edge services closer to data
  • Data Integration: Manage data using Spring Data and integrate distributed services with Spring-supported event-driven, message-centric architectures
  • Production: Make your system observable; use service proxies to connect stateful services; understand the important ideas behind continuous delivery

If you’re building cloud-native applications, this book will serve as your essential guide to using the Java ecosystem. It covers everything—building resilient services, managing data flows (via REST and asynchronous events), testing, deployment, and observability.

—Daniel Bryant, Software Developer and CTO at SpectoLabs

Whether you’re just starting out on your cloud-native journey or nearing your cloud-native goals, everyone involved will benefit from the insights and experiences shared in this Cloud Native Java book.

—Dr. Dave Syer, Contributor to the Spring Framework, and Co-founder of Spring Boot and Spring Cloud
