Real-Time Chat Server Architecture with Kotlin and Spring

Building a chat system that handles thousands of simultaneous users requires a deep understanding of real-time communication and system scalability. This course provides a clear path for developers to transition from basic web applications to complex, event-driven architectures. You will learn how to manage persistent connections, handle data flow in real-time, and ensure your server remains responsive under heavy load. Through detailed written explanations and code examples, you will master the principles of distributed processing and performance tuning. The curriculum starts with foundational concepts of messaging protocols and basic server setup before progressing to advanced topics like horizontal scaling and asynchronous task management. What you'll learn: - Understand the fundamentals of WebSocket communication for persistent real-time connections. - Implement efficient message handling using Kotlin coroutines and asynchronous programming patterns. - Apply distributed processing concepts to ensure your server scales across multiple instances. - Configure Spring Boot for high-concurrency environments and real-time data flow. - Practice performance optimization techniques to reduce latency and improve system throughput. - Explore modern messaging patterns and state management in a distributed environment. The course begins with essential terminology and core communication concepts, moving systematically into server implementation and optimization strategies. This program is designed for developers who are new to real-time systems and want to build robust, scalable backends without any prior experience in distributed architecture.
