Does anyone know what Reddit's AWS monthly bill is these days? I suspect they would be closer to profitability if they ran their own hardware, but I haven't seen any numbers recently.
Don't forget that if they were to run their own hardware, they'd probably need a couple of sysadmins to manage it. The question is if running their own hardware would be cheaper by more than the salary of a couple employees.
In previous talks they have never revealed the numbers, but have said that their bills have been fairly constant over time - Amazon's price decreases have balanced growth in AWS usage.
