Hi , I’m using actually two servers wowza version 3.5.0 running on Windows 2008R2. the first server is a physical hp dl380 G5 with two quad cpus ( 8 cores ) and 12 Gb of memory. The second is a virtual machine with 8 vcpu and 8 GB of memory. The load balancing is done our Cisco Ace and the media files are on a share. We only do a on demand streaming . - Rigth now We are consuming a 1.4GB Totatl Bandhwith ( in and out for two servers ) at apeek and we expect this to increase. My questions are related in case of moving those servers to aws network : 1 - Reffering to this thread [EC2 Instance Performance](http://community.wowza.com/t/-/427) I have to use 2 c1.xlarge instances to cover the need off bandhwith. 2 - should we use the aws Load Balancer or the wowza load balancer and Why ?. thanks. Mahmoud 3 - ---

Hi You will need to use the Wowza load balancer because sessions will have to stay on the server first allocated and it also supports RTMP redirection. Jason ---

Hello, I am interested in the Wowza Load Balanced configuration you were using with the Cisco ACE. We are interested in setting up a similar configuration and are wondering how you set this up. Thanks, Wes ---

What if he were using HTTP origin mode? I believe that doesn’t use sessions, correct?
