How to distribute rtmp stream via CDN?

Question

Adobe

Please tell me on what principle the distribution of HD video stream is arranged.
At the moment, using Adobe Flash Player, the content of the video camera in HD resolution is broadcast on Adobe Media Server (FMS (v5.x)). The Media Server receives the stream by means of the RTMP protocol, but cannot cope with the distribution of the broadcast to NN people (users) who are located in different parts of the globe. Please tell me what can be done to increase the speed of distribution of the stream, are CDNs or some other services used for this? Well, in general, the principle is of interest.

In your case, there are two main options, plus different hybrids based on them.
1. Give everything to the CDN. In this case, the Adobe server acts as an origin server, then the stream is sent to the delivery network, which itself decides which users should connect where and where to get data from. Plus approach - you do not worry about accessibility. The downside is it costs money.
2. Make your own delivery network with the origin-edge model. Your Adobe server will still work as a data source, plus you install several edge servers either in the same data center or closer to consumers (if possible). Next, the RTMP stream is published to the edge server. Further on the site in the web media players, paste the URL of the stream. You can choose the least loaded server yourself and give a direct link to the next one, or you can use the balancer. As a rule, the number of servers is chosen according to the throughput at the peak.
The advantage of the solution is that you completely control the working environment and spend exactly as much as necessary to process user connections. Minus - you need to spend some time setting up and then accompanying all this stuff.
Which is better for you is up to you. Our customers generally prefer to build their own delivery networks using our products.

If latency is not critical, that is, the gap that adds AMS for repacking video to HDS\HLS, it's easier to drive to these formats, and then all delivery turns into distribution of static media files. Of course, if you do not have DRM.
