I need to set up a new Wowza instance on EC2, which will need to take 50 incoming live RTMP webcam streams simultaneously (only 400kbps each), with client (viewer) connections likely to only be up to 10 max per stream at any one time (more often than not it'll be less or 0). Live streams will be viewable on a website, but also need to work over HLS for iUsers. Not a particularly demanding scenario, but I want to get it right straight up. Can anyone recommend which AMIs would be fine for this? Would m3.medium be up to the task, or do I need to go bigger?
