Hi all,

We intend using Wowza with Live HTTP origin and CloudFront with max expected concurrency of approx 300k viewers. This would be adaptive HLS with 4 cascades max being 720p stream @ 2500kbps.

Will a m2.4xlarge instance with transcoding and live HTTP origin via CloudFront be able to handle the same? Has anyone implemented such a large streaming with this amount of concurrent viewers in the past using Wowza & CloudFront?

Would appreciate any inputs/recommendation on the same.

VirtualStudio, when you find out, please share the configuration recommended by Wowa support.

I’m sure I’m not alone in wanting to know the answer.
