I was curious on anyone's thoughts about creating a highly available cluster of Wowza instances. Essentially, we're looking to use Wowza as an origin server delivering streaming content to one of our partner CDN's progressive media download services. Having multiple Wowza servers, all configured as live stream repeaters, we'd like the cluster to appear as one entity to our CDN. Short of a hardware loadbalance, in order to try our proof of concept, we're thinking of putting a web server (a separate server) in front of the Wowza instances to act as a software load balance and reverse proxy. We're considering using Nginx (or Apache Httpd) for this task. Are there any drawbacks or concerns that I should be aware of before considering such a setup?
