Book 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.
What you will learn
Apply SOLID principles to the hexagonal architecture
Assemble business rules algorithms using the specified design pattern
Combine domain-driven design techniques with hexagonal principles to create powerful domain models
Employ adapters to enable system compatibility with various protocols such as REST, gRPC, and WebSocket
Create a module and package structure based on hexagonal principles
Use Java modules to enforce dependency inversion and ensure software component isolation
Implement Quarkus DI to manage the life cycle of input and output ports
Who this book is 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.
