Does your WebRTC application need a media server? Many do, and the most important architectural design to make is whether you will use an MCU (Multipoint Control Unit) or an SFU (Selective Forwarding Unit). In this video, WebRTC.ventures founder and CEO Arin Sime will explain the differences between MCUs and SFUs and talk about why you might choose one over the other, and even scenarios where you might consider using both. This video is part of our series of short videos containing tips from our development team on live video application development using WebRTC, where we cover coding tips, use cases, and typical webrtc application architectures.
