A one-page decision aid: count your senders vs watchers, pick the topology (mesh / SFU / simulcast on SFU / hybrid), confirm simulcast or SVC, plan the broadcast tier and CDN, instrument tracking on both tiers, caption at scale, and the build-vs-buy line.

Fora Soft Video Engineering Handbook
This live class scaling checklist moves from senders versus watchers to mesh, SFU, simulcast or hybrid topology, then the broadcast tier and captions at scale. We wrote seven volumes covering the whole video stack; start with Volume 3 for WebRTC and SFUs, then Volume 2 for the broadcast tier, with Volume 1 for encoding. Written by Nikolay Sapunov, CEO at Fora Soft.
Live classes break down past a few dozen students and you need the right topology?
Tell us your class sizes and interaction needs, and we will pick the topology, simulcast settings and broadcast tier that hold up at your peak. 250+ video products shipped since 2005.
