Advanced Java, Spring Boot & Microservices Guide

Introduction: How Do Modern Apps Handle Massive Traffic? Every second, millions of users interact with online platforms—ordering food, transferring money, watching videos, or shopping online. These platforms must process thousands of requests simultaneously while maintaining speed, reliability, and security. In the early days of web development, most applications were built as single large systems called monolithic applications. While this approach worked for smaller systems, it became difficult to maintain and scale as applications grew larger. To solve these challenges, developers began adopting modern frameworks and architectures. Technologies like Advanced Java, Spring Boot, and Microservices architecture have become essential for building scalable and flexible applications. Because these technologies are widely used in enterprise development, many learners are interested in understanding them deeply. For beginners who prefer learning technical concepts in their native language, in
