Udemy – Scalable Real-Time Backends with WebSockets 2025-8

Scalable Real-Time Backends with WebSockets is a course on how to design, build, and deploy backend systems published by Udemy Online Academy. This is a hands-on course that teaches you how to design, build, and deploy real-time backend systems that are capable of handling high traffic and instant communications. Learners will explore WebSocket fundamentals, connection management, and scaling techniques to ensure efficiency, reliability, and performance. This course is great for developers who want to add real-time features like chat, notifications, or live updates to their applications.

Understanding frontend workflows, designing APIs, choosing the right protocols and databases for the job, and determining communication patterns—whether the workload is CPU-intensive or I/O-intensive—are all part of the fun of this course. However, what is truly challenging is designing real-time backend applications that support unrestricted, ad-hoc, two-way communications. Gaming, chat, and even mission-critical real-time workloads are unique in that they require the “push” nature of the connection to function effectively. WebSockets is by far the most widely available two-way protocol, supported across all clients—from browsers and command-line applications to runtimes like Node and Bun, and even other languages like C and Go.
