A quick question. How many copies of the same movie are kept in a video server (a video streaming server)? Suppose a particular video is at max requested by 1000 users at the same instant of time, how many copies would be sufficient so that parallel streams can be provided to each user? Ideally 1 copy would solve the purpose, but what is the optimum number keeping the bandwidth and simultaneous access in mind?
