I invested 2 minutes of my time and found: https://aws.amazon.com/solutions/live-streaming-on-aws/ https://aws.amazon.com/solutions/live-streaming-on-aws/ and https://aws.amazon.com/mediaconvert/pricing/ https://aws.amazon.com/mediaconvert/pricing/ Assuming you trial a MVP using AWS those two pages might give you some indication of ball park costs. If you are looking at co-lo provisioning then you will probably need to plunk down in the order of USD10,000 to USD50,000 to test the waters. Either way, in the long term I think your per minute per connection costs will probably be in the order of the AWS costings. After all, they do that sort of thing on a massive scale and have a great deal of experience. Good luck with your planned venture.
