7 Gb/s * 0.125GB/Gb * 86,400s/d * 30d/mo * 0.0009765625TB/GB = 2215TB/month to 738TB/month ("20,000 users at night", 1/3 peak usage - 8hrs)

EDIT: I give up on the conversion

I went to a talk once with Jeff Barr of Amazon Web Services. The owners of SmugMug charge all of their AWS on a corporate credit card. We're talking multiple roundtrip tickets from bonus points a month.

It's just over 200 terabytes.

I've seen traffic advertised at €15/TB in Germany, that's €3.000/month.

EDIT: I screwed the units up a few times, sorry

You can simplify your query by letting Google do the units conversion. Eg, search for:

    86400 seconds/day + 1

To get the same result as your link google:

    0.7 gigabit/second * 30 days

Or even:

    0.7 gigabit/second * 1 month

Or ask WA: http://www.wolframalpha.com/input/?i=7Gb%2Fs+to+TB%2Fmonth

7Gbits/s saturated over a month is 2,247 TB

http://www.google.com/search?hl=en&q=7Gb%2Fs+in+TB%2Fmon...

So at your €15/TB i would be €33,705 / month

Also €15/TB seems low as prices around the US are $0.10/GB so $100/TB which would equate to around $200k/month

Of course when you are pushing that much data you're going to want to pay per Mbit/s and with bandwidth as low as $3/Mbit we get around $21,000/month

What is probably happening here is that this guy has 7 dedicate servers at about $150 each per month that have a gigabit connection with say a couple of TB data allowance for each server and he's just saying that he has a capacity of 7Gb/s. The chat client is probably peer to peer so the video bandwidth for him is not that critical.

> 7Gbits/s saturated over a month is 2,247 TB

Even the best calculation is wrong when you plug in the wrong friggin data... I confused myself from converting gbit to GB and ended up with 0.7 gbit instead of 7 .. :-S

> Also €15/TB seems low

That's why I do business with them :) It's hetzner.de, and their "rootserver" (€49/month and up) comes with 2.000 GB free traffic. Extra is free, but capped at 10 mbit, or €14.90/TB. The servers are connected at 100 mbit, though. I'd guess that's just to keep the ethernet infrastructure cheap, and a gbit connection would be possible for a fee.

I'm not affiliated with them, just a happy customer.
