Origin/Edge Questions

Hi folks.

Today, we have several NGINX systems deployed … most of it is for
caching
frontend to websites via anycasted instance.

A couple of our systems though involve video - streaming of realtime
linear
encrypted video. For that project, I’m looking to build out scale in the
system. Today, there are just a few NGINX systems providing an edge
function but to scale, we need to deploy a large scale origin/edge
scenario.
I keep looking around for reference designs and/or any whitepapers on
others
who have done this specifically with realtime encrypted linear video and
not
finding much . any ideas?

Thanks,

Paul
