    Default Streaming on EC2 Questions... Going live in a week!

    Hi, I'm going to start a weekly podcast and stream video live while we're recording every week so people can watch. I have 3 webcams and I'm using XSplit to control everything.... It's set up perfectly in terms of being able to stream to the site and switch between cams now. I had a few questions I was hoping someone with experience could answer when they had a minute before we go live in a week or 2.

    1. Is there any strain on my website's server from people just going to the live streaming page and sitting there watching? What if 2,000 people are watching? Is most of the strain on the Amazon EC2 server? Will it adjust and compensate for more people if I don't use the "small" instance and do the 64 bit Wowza version instead?

    2. I am on Fios, and my streaming tests on my site look great. I'm on 25MB/s download and 5MB/s upload. I can upgrade to 25 up and 25 down for $15 more a month. Would that be unnecessary and overkill for what I'm doing? I'd like to stream at a decent resolution. The tests looked good. I believe I was at 720p. Might have tried 1080p on one of them, but I'd have to go back and try again to be sure on that.

    3. I'd like to know how many people are watching the live stream when we broadcast. Someone told me about Cacti... But mentioned it's not really being supported in the latest Wowza versions on EC2. I was planning on using 2.4 for this, but wasn't sure if that's the best way to keep track of users, or if just installing Analytics was a good solution? Was told they have real time analysis now. Any suggestions on this? Is there any advantage to using 3.0 or higher?

    Thanks!
    Much appreciated!!!

    An m1-small gets about 150mbs bandwidth. The m1-xlarge gets about 350mbs. They do not adjust in anyway. You can use Wowza Liverepeater and the Dynamic Load Balancer to scale.

    5mbs uplink should be enough for what you describe, but more can't hurt.

    You can monitor real-time activity with these HTTPProviders:

    Otherwise, the best way to review is using logs. Sawmill has a Wowza module

    Thanks Richard... For the noobs, how many people is that roughly? Can it be calculated that way? Thanks!

    Like this: concurrent clients * bitrate / bandwidth.

    For example, a 500kbs stream with 150mbs is about 300 clients

    Awesome... And I realize these are all dependent on factors of viewers etc... But with the larger instance, it should work for about 900-1000 viewers if my calculations are correct?

    Yes, for a 500kbs stream.
