Real-Time Web Apps with SignalR and Azure Functions

Modern web applications demand instant updates without constant page refreshing, yet setting up persistent connections can quickly overwhelm traditional servers. By combining the scale of serverless Azure Functions with the real-time capabilities of SignalR, you can build highly responsive applications that scale effortlessly. This course teaches you how to establish seamless, bidirectional communication channels using modern .NET practices. You will transition from understanding basic polling to implementing fully event-driven, real-time architectures. Through clear explanations and practical code examples, you will learn how to broadcast updates, manage client connections, and handle high-throughput messaging without managing complex server infrastructure. What you'll learn: - Understand the core concepts of serverless architecture and real-time web communication - Configure Azure SignalR Service to work seamlessly with serverless backends - Bind Azure Functions to SignalR triggers and outputs for automated messaging - Manage client connection negotiations and group broadcasts securely - Apply modern .NET development practices including dependency injection and structured logging - Implement basic security patterns and token-based authentication for real-time hubs This course begins with foundational concepts, establishing clear definitions of serverless compute and real-time negotiation protocols. You will then progress through step-by-step implementation strategies, exploring connection management, group broadcasting, and error handling in production-like environments. This course is designed for beginner to intermediate backend developers, cloud enthusiasts, and .NET programmers who want to add real-time capabilities to their toolkit. No prior experience with SignalR or Azure is required, though a basic understanding of C# is recommended. Start reading today to unlock the power of serverless real-time communication.
