WebRTC on Amazon AWS

[vas2.0]

I am to launch a video conference service with abackend on Amazon EC2 cloud. Basically, this is video chats and video conferences of three users. We need to estimate possible performance of the server. How many chats one amazon server can bear? If there any statistics of use or data on how many call say Middle or Large Amazon instance can handle?

Performance is highly dependent on technologies and codecs used with each particular call. That is a WebRTC-WebRTC call via VP8 gives one performance, Flash-Flash gives other, WebRTC-Flash with transcoding will load up a server. Besides, Amazon are virtual servers so we do not have any testing data on Amazon. You can conduct tests yourself and see CPU usage on 1, 5, 10 calls at a time. According to our knowledge, load grows proprtionally, that is if one call consumes 0.5% of the CPU, then 10 calls will take about 5% of the CPU time.

Do you have some particular numbers? Let's say for 1000 or 10000 calls.

Unfortunately, we don't. To maintain integrity we always check performance on physical servers.
