SFU, MCU, or P2P: What’s the Difference Between These WebRTC Architectures?

  An added "benefits" that aren't mentioned: - SFUs can record / intercept the stream - SFUs can censor or change the stream That first one, I think, is actually a benefit for some applications. But I'm a bit curious why the article points out P2P is free and then use "cost" as a reason for SFUs. Also, from experience, P2P is not that simple to setup when firewalls are involved. So that is one instance of the article where it actually oversells P2P (in an article clearly written to sell SFU).

    You can send your frames encrypted even if there’s an SFU.

  A Selective Forwarding Unit (SFU) is a media server that receives media from each party in a conference call, decides which streams should be forwarded to other parties, and then forwards them.
