Live Streaming Infrastructure: What Scale Really Needs

Live streaming infrastructure moves video through ingest, media servers, transcoding and packaging, origins, CDN edges, and signalling systems, with different stages scaling according to stream volume, segments, or viewer counts. For large audiences, WebRTC is suited to low-latency interactive participants but requires server bandwidth for every viewer, whereas HLS uses CDN caching to serve watch-only audiences more efficiently at the cost of several seconds of delay; combining both tiers can limit per-viewer infrastructure costs. Egress requirements scale directly with concurrent viewers and delivered bitrate, so 1,000 viewers at 3,000 kbit/s require about 3 Gbit/s and 1.35 TB of data per hour, while origin shielding can greatly reduce origin traffic compared with direct edge requests. Major events often fail during sudden join spikes, which can overwhelm origins, signalling, chat, and WebRTC connection setup, making request coalescing, cache shielding, preplanned capacity, redundancy, and load testing important. Provider selection should rely on documented and dated concurrency limits, pricing, latency, protocols, regional coverage, and service-level commitments. VideoSDK is presented as supporting this two-tier pattern through interactive room-based streaming and HLS output, with organisation and room quotas, WHIP ingest, and separately billed WebRTC and HLS viewer usage.
