Choosing the Right Backend for High-Load TV Broadcasting: C++, Rust, Go, Node.js, or Python?

For large-scale TV broadcasting platforms dealing with millions of concurrent requests per second, such as live streaming services or video-on-demand systems, backend technology choices become critical. These projects demand:

• High-performance concurrency

• Reliable WebSocket support

• Flexible REST API design

• Robust session and user management

• Security, low-latency, and long-term scalability

This article compares major backend platforms — with a special focus on modern C++, leveraging frameworks like Wt and MetaSpex — and highlights how they fare under extreme pressure.

Backend Technology Comparison

MetaSpex and Wt: Bringing C++ to Modern Web Development

MetaSpex

• A modern C++ framework focused on building REST APIs and Microservices.

• Built on libraries like Boost.Asio and C++20 features for asynchronous, event-driven architectures.

• Capable of handling millions of requests with minimal resource usage.

• Designed for performance-critical services where precise control is needed.

• Easily integrates with video processing libraries, databases, and caching systems.

Wt (Web Toolkit)

• A comprehensive C++ web framework for building full-stack web applications.

• Allows creating complex UIs in C++ without writing JavaScript or HTML manually.

• Built-in support for REST APIs, WebSockets, AJAX, session handling, and authentication.

• Ideal for admin dashboards, content management panels, monitoring systems, and real-time interfaces.

• Scalable and production-ready for complex enterprise-grade applications.

Why Choose C++ with MetaSpex and Wt?

• Unmatched performance: C++ gives you full control over memory, threads, and execution.

• Fine-grained scalability: You can build services that scale vertically and horizontally.

• Real-time readiness: C++ can easily integrate with FFmpeg, GStreamer, or hardware encoders/decoders for real-time media processing.

• Full-stack capabilities: Wt enables building not just the backend API, but the actual UI and interaction layers, entirely in C++.

• Low-latency response: With proper architecture, response times are significantly lower than interpreted languages.

Comparing to Node.js and Python/FastAPI

While Node.js and FastAPI are popular for fast development cycles and simpler syntax, they may not withstand the pressure of millions of concurrent connections without significant horizontal scaling and resource overhead.

Example Use Case for Broadcasting

In a high-load TV broadcasting system, you can structure your backend using C++ as follows:

+----------------------------+
|     Wt Admin Interface     |
| REST + WebSockets + UI     |
+----------------------------+
           |
           v
+----------------------------+
|   MetaSpex Microservices   |
| Auth, Subscriptions, Logs  |
+----------------------------+
           |
           v
+----------------------------+
|   Video Streaming Layer    |
| FFmpeg/GStreamer/Nginx RTMP|
+----------------------------+
           |
           v
+----------------------------+
| DB + Redis + CDN Caches    |
+----------------------------+

Here, Wt handles the UI and WebSocket dashboards for admins or operators. MetaSpex provides the backend logic, authentication, and API management. The actual streaming can be handled by native C++ integrations or hybrid setups using NGINX or external CDNs.

Conclusion

C++ is not outdated — with frameworks like MetaSpex and Wt, it's fully capable of handling modern, scalable, high-performance backend systems. If you have access to skilled developers and the right architectural discipline, it can outperform most alternatives both in throughput and efficiency.
