Ever felt lost in conversations where terms like “scalability” and “five-nines availability” fly around? This book transforms complex Non-Functional Requirements (NFRs) into clear, visual insights using hand-drawn sketchnotes and illustrated system design concepts. Instead of dense theory, you’ll learn through intuitive diagrams, real-world scenarios, and practical patterns that make NFRs easy to understand and apply. Discover how to design resilient, secure, and high-performance systems—and turn NFRs into your secret weapon for building systems that truly scale.

In this first step, you will build your first Spring Boot app and configure your development environment. The course will teach you the ins and outs of dependency management, application configuration via properties and YAML files, and more. Annotations, data source integration with Spring Data JPA, and RESTful service construction are some of the more advanced topics that we will cover as we go along. I will demonstrate how to incorporate Spring Security authentication and authorization, two essential components of any application. In this lesson, you will find out how to secure your application from intruders by configuring basic authentication, URL authorization, and JWT authentication.

Java has evolved far beyond its old stereotypes of verbosity and rigidity. Recently, it has embraced modern programming paradigms and introduced features that make it more concise, flexible, and expressive. This transformation includes adopting functional programming with lambda expressions and streams, introducing records for simpler data classes, and using pattern matching for more readable code. Java’s modern iterations also bring enhanced concurrency with virtual threads, efficient memory management, and streamlined APIs like the new Date-Time API and HttpClient. This book will explore how these advancements have revitalized Java, making it a powerful language for today’s fast-paced development environment. Whether you're processing large data sets, building scalable applications, or writing more expressive code, modern Java provides the necessary tools. Get ready to discover a new side of Java that's more versatile and relevant than ever.
