Taking steps a bit further, it would be interesting to know what variation saves what money. Eg if your load is 80% of the time between 80-100k connections but the 20% at 250k, you save $500 a month using serverless or vice versa. Is it as simple as $60k/number of connections? If so the cross over point would be just 6250 connections as your base load. IMO, that $1500 server starts to look very appealing very quickly but I imagine it isn't as simple as that.
