Currently I am doing a research for building live video stream platform on AWS EC2 instances and I need to know what is the best instances type for Wowza and how many instances do I need for 1000 live stream concurrently in HD 720p ---

I have read the article but it is doesn’t say anything about concurrent inputs and I found some benchmarks here [https://www.wowza.com/docs/wowza-transcoder-performance-benchmark](https://www.wowza.com/docs/wowza-transcoder-performance-benchmark) but there is something unclear about benchmark which is why if there is more than 10 inputs the output is limited to 10 ---

Hi Abdalrahman, the benchmark you read about transcoding/transrating, if you dont need to transcode your 720p stream to the 480p 360p 240p 160p , then the benchmark is useless for you. If I’m not mistaken, In wowza the suggested live stream number is 100 at least 200 for per instance. I can get 120 live stream in a single 32 gb ram 24core E5 2.x cpu with centos os. You cant handle 1000 concurrent live stream input I guess, not only because of the cpu or gpu but also ethernet port limit & java limit . You need to distribute them. if you need to transcode stream, I can give example from my ip cam system . It use nvidia k2 grid gpu , run on centos os input : 50 live 1080p stream and transrating to 480p,360p . ---

/dont mean to highjack the post, but i can’t send you a personal message on this forum. Emre, can you tell me more about your transcoding setup. You are running 50 input streams 1080p @ ?? Mbps input and to how much streams can you transcode that?, also 50? Im curious about the nvidia cards transcoding. What is your other hardware in that ipcam setup? ---

1080p at 4-6mbits ps, sony & axis ip camera. with 48 core cpu I cant transcode/transrate 50 concurrent ip camera. with nvidia k2 grid and 24 core cpu on centos. Only gpu transcoding cpu not used. I see the %70-80 gpu usage via nvidia-smi cli for both of card.
