WebRTC is awesome. But... it doesn't scale, at least out of the box. What if you wanted 5 people on a call? 20? 1000? Can WebRTC do that? With the help of an SFU or MCU media server... absolutely! We'll look at how WebRTC does things, why this is creates unavoidable drawbacks, and how to overcome them with either a selective forwarding unit (SFU) or a multi-point control unit (MCU). We'll compare them and help you find which one is right for your project! Hit subscribe and tune in to more WebRTC videos!
