Great article Tsahi! I have just made the whole team read it, and are getting a quiz on Monday. I’ll update you on the results.

Not all components of the machine scale at the same rate – biggest machine has only x4 faster network than the largest machine (according to advertised numbers). In reality, network performance is capped by amount of cores processing network stack, the fact that webrtc is mostly UDP packets, etc.

So that c5.18xlarge != 9 * c5.2xlarge.

this is from chrome where your link works.. does not work for me in either firefox regular or dev.. does work in opera.

also, when I tried to reply to your comment in firefox I was dished up a WP error.. “Comment is a spam.” 🙂

anyway all good.. I signed up but my normal address did not receive anything so i used a gmail account and all was fine..

David – not sure why. What browser are you using?

I was trying to avail myself of your kind offer…

“…Check out this free video course on the untold story of the WebRTC servers backend…”

I switched all the script/tracking/ad-blocking widgets but the links don’t seem to go anywhere..

This whole page is helpful btw.. thanks as usual!

In reply to Philipp Hancke.

Thanks. I liked the way Vogel explained it.

And definitely thanks for the cost angle – somehow I failed to mention it or even think about it when writing this article.

Great post! I like the “blast radius” concept.

On AWS you’ll usually pay at least 10x as much for the network traffic as you do for the CPU, making the cost of additional machines relatively irrelevant. Which will also affect decisions like how to deploy stuff. Of course, once you realize how expensive AWS is for running media servers you will need to reconsider all that 😉
