I am curious the infrastructure cost of running a streaming audio site with 50K to 100K users per month. Users would be uploading files to server and streaming them.
Does anyone know of a link resource that details this type of information or able to detail their experiences? Does not need to be specific regarding stated monthly users.
About $400/mo for a half cabinet and some power. You're in the neighborhood of probably $500-$900/mo.
Why colocation instead of some shared or pseudo-dedicated server some place? Because (IMO and IME) you're better off with any site that is going to do streaming and potential sustained throughput in colo facility with fixed costs. Places like Rackspace just love when you go 10x over their pitiful limits and your $200 monthly plan is suddenly $4000. Kind of hard to budget for.
Of course, I'm also biased, having an interest in a colo facility :)
