Designing Hexagonal Architecture with Java
A practical guide for software architects and Java developers to build cloud-native hexagonal applications using Java and Quarkus to create systems that are easier to refactor, scale, and maintain Key FeaturesLearn techniques to decouple business and technology code in an applicationApply hexagonal architecture principles to produce more organized, coherent, and maintainable softwareMinimize technical debts and tackle complexities derived from multiple teams dealing with the same code baseBook Description Hexagonal architecture enhances developers' productivity by decoupling business code from technology code, making the software more change-tolerant, and allowing it to evolve and incorporate new technologies without the need for significant refactoring. By adhering to hexagonal principles, you can structure your software in a way that reduces the effort required to understand and maintain the code. This book starts with an in-depth analysis of 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 by using ports and use cases in the Application hexagon, and make your software compatible with different technologies by employing adapters in the Framework hexagon. Moving on, you'll get your hands dirty developing a system based on a real-world scenario applying all the hexagonal architecture's building blocks. By creating a hexagonal system, you'll also understand how you can use Java modules to reinforce dependency inversion and ensure the isolation of each hexagon in the architecture. Finally, you'll get to grips with using Quarkus to turn your hexagonal application into a cloud-native system. By the end of this hexagonal architecture book, you'll be able to bring order and sanity to the development of complex and long-lasting applications. What you will learnFind out how to assemble business rules algorithms using the specification design patternCombine domain-driven design techniques with hexagonal principles to create powerful domain modelsEmploy adapters to make the system support different protocols such as REST, gRPC, and WebSocketCreate a module and package structure based on hexagonal principlesUse Java modules to enforce dependency inversion and ensure isolation between software componentsImplement Quarkus DI to manage the life cycle of input and output portsWho this book is for This book is for software architects and Java developers who want to improve code maintainability and enhance productivity with an architecture that allows changes in technology without compromising business logic, which is precisely what hexagonal architecture does. Intermediate knowledge of the Java programming language and familiarity with Jakarta EE will help you to get the most out of this book.

Release Date: 2024-12-31
Develop innovative architectural styles by analyzing and merging various approaches, focusing on making trade-offs and mitigating risks to solve real-world problems Key Features Learn how to analyze and dissect various architectural styles into building blocks Combine existing ideas with your own to create custom solutions Make informed decisions by navigating trade-offs and compromises Purchase of the print or Kindle book includes a free PDF eBook Book DescriptionSoftware Architecture with Kotlin explores the various styles of software architecture with a focus on using the Kotlin programming language. The author draws on their 20+ years of industry experience in developing large-scale enterprise distributed systems to help you grasp the principles, practices, and patterns that shape the architectural landscape of modern software systems. The book establishes a strong foundation in software architecture, explaining key concepts such as architectural qualities and principles, before teaching you how architectural decisions impact the quality of a system, such as scalability, reliability, and extendability. The chapters address modern architecture topics such as microservices, serverless, and event-driven architectures, providing insights into the challenges and trade-offs involved in adopting these architectural styles. You’ll also discover practical tools that’ll help you make informed decisions and mitigate risks. All architectural patterns in this book are demonstrated using Kotlin. By the end of this book, you’ll have gained practical expertise by using real-world examples, along with a solid understanding of Kotlin, to become a more proficient and impactful software architect.What you will learn Master the fundamental principles of architecture and design Explore common architectural styles and their applicable scenarios Analyze, break down, compare, and design architectural styles to solve practical problems Reason, negotiate, and make difficult choices in the absence of ideal solutions Mitigate risks when making compromises and trade-offs Create scalable, sustainable, maintainable, and extendable software systems Use the Kotlin programming language to achieve your architectural goals Who this book is for This book is for developers with basic Kotlin knowledge seeking a deeper understanding of architecture, Kotlin Android developers who are starting to get involved in backend development, and Java developers transitioning to Kotlin. It's also ideal for software architects who are less experienced in Kotlin and want to enhance their skills, as well as those who enjoy discussing and exploring unique architectural concepts.
Fundamentals of Software Architecture
DESCRIPTION With the rising complexity of modern software systems, strong, scalable software architecture has become the backbone of any successful application. This book gives you the essential knowledge to grasp the core ideas and methods of effective software design, helping you build strong, flexible systems right from the start. The book systematically navigates the critical aspects of software architecture, commencing with a clear definition of its significance and the pivotal role of the software architect. It delves into fundamental architectural properties like performance, security, and maintainability, underscoring the importance of modularity in crafting well-structured systems. You will explore various established architectural styles, including microservices and layered architecture, alongside key design patterns such as MVC and repository, gaining insights into their practical application. The book further elucidates the function of software components, the art of architecting for optimal performance and security, and essential design principles for building robust solutions. Finally, it examines the impact of modern development practices (Agile, DevOps), positions architecture within the broader engineering context, emphasizes the importance of testing at the architectural level, and offers a glimpse into current and future trends shaping the field. By the end of this book, you will have a solid understanding of the core concepts, helping you to contribute effectively to software design discussions, make informed architectural decisions, and build a strong foundation for creating high-quality, future-proof software systems. WHAT YOU WILL LEARN ● Define core architecture, architect roles, and fundamental design attributes. ● Apply modularity principles for resilient and adaptable software design. ● Design cohesive components, manage coupling, and optimize system decomposition. ● Cultivate essential soft skills for effective leadership and stakeholder management. ● Define technical requirements and understand modern development practices. WHO THIS BOOK IS FOR This book is for software developers, technical leads, and anyone involved in software creation, seeking a foundational understanding of software architecture principles and practices to enhance their design skills and project outcomes.
