Yes, a small EC2 instance should be able to handle ~100 simultaneous sessions at 1 Mbps each. When looking at bandwidth (stream bitrate \* # of concurrent streams), we advise adding in a factor of 20% overhead for network capacity, so with a 1 gbs NIC would be about 800kbs throughput. You can request the [load test tool](https://www.wowza.com/docs/how-to-get-flash-rtmp-load-test-tool) to help test your setup. -Lisa ---

Hi, I’d like to make sure I am getting my pricing correct. Here is a hypothetical situation: a) I need to store approximately 6TB of movies on the cloud. For that, I plan to use Amazon S3. b) Based on subscriber data that I have, I expect, monthly there will be a total of 200TB of data out that I expect from the S3 server to various subscribers as they stream these movies c) Next, I also need to host Wowza instances. I was told that each Wowza instance, on an EC2 small config can handle approx 100 simultaneous sessions at 1Mbps each. However, in my case, if I am already paying S3 for the bandwidth usage, do I need to worry about load with my Wowza instances as much? My assumption is the Ec2 instances running Wowza will not be streaming the actual content - S3 will. Wowza will more or less be the control side of things. Is this correct? thx ---

Did I get my amazon costs right ( ballpark assuming both S3 and Ec2 are in the same US region)? I will add 20%
