Description

We live in a fast-evolving world with new technologies emerging every day, where enterprises are constantly changing in an unending quest to be more profitable. So, the question arises — how to develop software capable of handling a high level of unpredictability. With this question in mind, this book explores how the hexagonal architecture can help build robust, change-tolerable, maintainable, and cloud-native applications that can meet the needs of enterprises seeking to increase their profits while dealing with uncertainties. This book starts by uncovering the secrets of the hexagonal architecture’s building blocks, such as entities, use cases, ports, and adapters. You’ll learn how to assemble business code in the domain hexagon, create features with ports and use cases in the application hexagon, and make your software compatible with different technologies by employing adapters in the framework hexagon. In this new edition, you’ll learn about the differences between a hexagonal and layered architecture and how to apply SOLID principles while developing a hexagonal system based on a real-world scenario. Finally, you’ll get to grips with using Quarkus to turn your hexagonal application into a cloud-native system. By the end of this book, you’ll be able to develop robust, flexible, and maintainable systems that will stand the test of time.

Who is this book for?

This book is for software architects and Java developers looking to improve code maintainability and enhance productivity with an architecture that allows changes in technology without compromising business logic. Intermediate knowledge of the Java programming language and familiarity with Jakarta EE will help you to get the most out of this book.

What you will learn

Apply SOLID principles to the hexagonal architecture

Assemble business rules algorithms using the specified design pattern

It is a comprehensive and enlightening journey into the world of hexagonal architecture and Quarkus, tailored to Java developers and software architects. From the outset, it emphasizes the importance of building robust, resilient, and cloud-native applications capable of withstanding unpredictability – a vital requirement in the modern software industry. It is a must-read for software architects and Java developers seeking to enhance code maintainability and adaptability. It provides a solid foundation in hexagonal architecture, offers practical insights into its implementation, and shows how to harness the power of Quarkus for cloud-native applications.

POE Oct 20, 2023

This book covers the ports and adapters pattern, also referred to as hexagonal architecture, using Java and Quarkus. The book provides a clear and detailed introduction into this architecture. There are sufficient examples throughout the book to help us understand how to use hexagon applications and how to build the hexagon framework. There is a section that covers how to use Quarkus for a modernized approach. Overall, a great read!

Why, on earth, in this book input ports implement use cases, not the other way around?I highly recommend another book on this topic: "Get Your Hands Dirty on Clean Architecture, Java, 2nd Edition". That one is up to the point with many practical insights. Or just read some articles by the creator of Hexagonal Architecture.I got nothing from the superficial rendering of many subjects (DDD, Hexagonal, Quarkus) in this book.
