Nextcloud Talk High-performance backend requirements¶

Here you find the minimum system requirements for the Talk High-Performance Back-End (HPB) and how to configure the Network interface to enable communication between the HPB, Nextcloud and the users.

Talk specific terminology¶

• HPB: High-Performance Back-End, the whole server with all its components
• SFU: Selective Forwarding Unit, this is one component of the HPB. The SFU collects all the media streams and sends them out to all participants again.
• Signaling Server: Another component of the HPB which handles the signalling between the server and the participants, e.g. "user X joined a call".

Minimum system requirements¶

• 8 GB RAM
• 32 GB free disk (for caching, data will not be stored)
• 4 Cores i7/Xeon (must support AES)
• This setup is estimated to work for at least about 150 concurrent users
• It should suffice for far larger numbers when talking about webinars or small (1-5 participants) meetings. See below for some examples.
• Supported operating systems:
  • Ubuntu Linux (LTS), 18.04, 20.04, 22.04
  • Debian 10, 11
