As a theoretical exercise and not knowing for one second if this would in anyway work, but... Don't use Python. Use Java. Store file in instance memory. Should be able to serve it with latency of 25ms or even less. So 40 requests per second for just one thread. Should be able to get at least 20 threads going per instance or more if new scheduler is good since their will be zero cpu utilization. So you're looking at 2500 instances max plus or minus. I'd also prime the pump so to speak. When you know it's going to happen start hitting your instances from several other places like perhaps AWS to start kicking up instances. You're paying for the 15 minutes anyway. Get as many instances pre-started as possible and ready to go.
