Can you (or someone) shed some light to help me understand how this would ramp up to millions? Both for curiosity’s sake, and to make sure my self-deployed projects (0 AI, all manually configured) don’t bankrupt me.
Real wholesale bandwidth pricing is about a hundred times cheaper than that, and incoming bandwidth is often free. You could rent a server with 100Gbps connection, 10000TB/month outgoings cap (maybe), and have the AI spam packets to it, and mostly not reply to them. It would be expensive but not nearly as expensive as it would be for the guy on AWS.
Do some calculations: 100Gbps is 12.5 GBps which is about one dollar per second. Okay so maybe not millions of dollars but still a hundred thousand per day, while you are spending maybe 1000-3000 per month and cancelling after the first month.
It is alsi worth mentioning that it is just billed different. You either pay per port (and can use entire bandwidth) or per 95th percentile of the monthly speed usage. So if your traffic isn't spiky but consistent, you'd pay even less than "hundred times cheaper".
At most I think you could negotiate CloudFront rates, but even then, the sob story would be if you had been DDoSed and got hit with this traffic and AWS failed to protect you from this attack. Actively creating the outbound traffic is something that I don't see how AWS would be sympathetic to providing any refunds.
