Why Major Tech Companies Are Investing in Video Streaming Architecture
Major tech companies are investing in a new video streaming architecture to reduce latency and improve scalability as demand grows for live streaming, real-time communication, and immersive content like AR and VR.
Background
- The article discusses a shift from traditional HTTP-based adaptive streaming (used by Netflix, YouTube, etc.) toward a newer architecture called **Media over QUIC (MoQ)** or similar low-latency streaming protocols.
- **QUIC** is a transport protocol developed by Google and now standardized by the IETF; it runs over UDP instead of TCP, reducing connection overhead and latency. Major tech companies (Google, Meta, Apple, Cloudflare) are investing heavily in making video work natively over QUIC.
- Traditional streaming (HLS, DASH) relies on TCP and HTTP/2, which introduce buffering and delay — fine for on-demand video but problematic for live/interactive use cases like gaming, live sports, video calls, or AR/VR.
- The push matters because next-generation applications (metaverse, real-time collaboration, cloud gaming) demand **sub-second latency** and reliable delivery even on congested or mobile networks — something TCP-based streaming cannot guarantee.
- Prior context: Streaming video accounts for the majority of internet traffic; even small improvements in efficiency/latency have enormous financial and infrastructural implications for cloud providers, CDNs, and platform companies.
