Preface

Software architecture is the cornerstone of software systems, shaping their scalability, performance, and maintainability. As software demands evolve, so does the need for flexible, efficient, and secure architectures. Spring Framework 6, with its comprehensive ecosystem and advanced features, serves as an excellent foundation for building scalable and resilient applications.

This book embarks on a journey through software architecture, starting with the fundamentals, introducing decision-making processes in software architecture, and exploring the importance of understanding the system context.

Using an online auction application as a case study, we evolve it through various architectural styles to reflect real-world software needs, addressing both functional and non-functional requirements. This approach ensures each concept is explained theoretically and brought to life through practical examples. You’ll witness the application’s transformation from a monolithic structure to distributed microservices and beyond, showcasing the progression of architectural decisions in modern software projects.

The book also delves into vital areas such as security, observability, testing, performance optimization, microservices orchestration, and CI/CD pipelines, providing a comprehensive toolkit for building enterprise-ready applications.
