This book will show you how to build Java-based microservices architecture using the popular Spring Boot framework by evolving a small monolith application to an event-driven architecture composed of several services. This third edition has been updated to cover Spring Boot 3, including its compatibility with Java 17 and Jakarta EE 10, and employs an incremental approach to teach the structure of microservices, test-driven development, and common patterns in distributed systems such as service discovery, load balancing, routing, centralized logs, per-environment configuration, and containerization. Authors Moisés Macero and Tarun Telang get the ball rolling by introducing you to the fundamentals of microservices and Spring Boot before walking you through the development of a basic Spring Boot application. You’ll then see how to build a front end using React, and learn how to use the data layer to read and write data from and to other systems via Spring Boot and its access to Spring Data and its available APIs. Putting together what you've learned thus far, you’ll begin to transform an application from a monolith to a microservice. This pragmatic approach will enable you to better grasp the benefits of using this type of software architecture, instead of keeping you distracted with theoretical concepts. The emphasis is on what matters most, starting with the minimum viable product, while maintaining the ability to adapt and improve your application as needed. After completing this book, you will have the foundational knowledge necessary to build your own microservice-based applications using Spring Boot. What You Will Learn Gain a thorough understanding of microservices architecture and how it differs from monolithic architectures.Discover the step-by-step process of breaking down a monolithic application into smaller, focused servicesBuild microservices with Spring Boot 3, Spring Data, Spring Cloud, React.js, Docker, Cucumber, and moreDevelop Java-based microservices using the latest version of Spring Boot, compatible with Java 17 and Jakarta EE 10.Discover architecture patterns for distributed systems such as asynchronous processing, eventual consistency, resilience, scalability, and moreGain insight into event-driven communication patterns and understand how to design and build event-driven microservicesTrace every request from beginning to end with Sleuth and centralized loggingDeploy your microservices anywhere as Docker containers Who This Book Is For Those with at least some prior experience with Java programming. Some prior exposure to Spring Boot recommended but not required.

Get ready to develop microservices using open source Eclipse MicroProfile and Jakarta EE, and deploy them on Kubernetes/Docker. This book covers best practices for developing cloud-native applications with MicroProfile and Jakarta EE.This book introduces you to cloud-native applications and teaches you how to set up your development environment. You'll learn about the various components of MicroProfile, such as fault tolerance, config, health check, metrics, and JWT auth. You'll develop a RESTful web service made up of some microservices. You'll deploy your application on Docker and Kubernetes.After reading this book, you'll come away with the fundamentals you need to build and deploy your first cloud-native Java-based app.What You'll LearnBuild your first cloud-native Java-based app with the open source MicroProfile platform, and Jakarta EE 10 APIs Develop a RESTful web service using MicroProfile and Jakarta EEDiscover and explore the key components of the MicroProfile framework, such as config, metrics, health, JWT authentication, and moreDeploy your cloud-native application on the Kubernetes container orchestration platformGet up to speed with other popular technologies such as Docker containers, Kubernetes clusters, and ZipkinWho This Book Is ForProgrammers with at least some prior experience in Java programming who may be new to MicroProfile and Jakarta EE. Some prior experience with Java-based microservices and web development is recommended, but not required.

Take a problem-solution approach for programming enterprise Java or Java EE applications and microservices for cloud-based solutions, enterprise database applications, and even small business web applications. Java EE to Jakarta EE 10 Recipes provides effective, practical, and proven code snippets that you can immediately use to accomplish just about any task that you may encounter. You can feel confident using the reliable solutions that are demonstrated in this book in your personal or corporate environment. Java EE was made open source under the Eclipse Foundation, and Jakarta EE is the new name for what used to be termed the Java Platform, Enterprise Edition. This book helps you rejuvenate your Java expertise and put the platform’s latest capabilities to use for quickly developing robust applications. If you are new to Jakarta EE, this book will help you learn the features of the platform and benefit from one of the most widely usedand powerful technologies available for cloud-native enterprise application development today. Examples in this book highlight Jakarta EE’s capabilities, helping you to build streamlined and reliable applications using the latest in Java technologies. The book takes a problem-solution approach in which each section introduces a common programming problem, showing you how to solve that problem in the best possible way using the latest features in Jakarta EE. Solutions in the form of working code examples are presented that you can download and use immediately in your own projects. Clear descriptions are provided to help you understand and learn to build further on the solutions provided. This is the ideal book for the code-focused programmer interested in keeping up with the future of enterprise development on the Java Platform. What You Will Learn Develop enterprise java applications using the latest open-source Jakarta EE platformCreate great-looking user interfaces using Jakarta Servlets, Jakarta Server Pages, Jakarta Server Faces and the Eclipse Krazo framework (an implementation of Jakarta MVC)Build database applications using Jakarta NoSQL, Jakarta Persistence, and Jakarta Enterprise Beans.Develop enterprise grade applications using Context & Dependency Injection, and Jakarta RESTFul web servicesAutomate testing through cohesive test suites built on Arquillian for Jakarta EE applicationsBuild loosely coupled distributed applications using Jakarta MessagingDeploy microservices applications in cloud environments using DockerSecure applications utilizing the Jakarta EE Security API Who This Book Is For Java developers interested in quickly finding effective and proven solutions without reading through a lengthymanual and scrubbing for techniques.
