Tor relays in the Amazon cloud: usage charges

I recently found out about Tor Cloud and think it’s a great idea.

In a nutshell, you can strengthen the Tor network with a few clicks and a small amount of money paid to Amazon.

But how much does it actually cost to run a Tor relay on Amazon’s EC2 service?

Here is what I’m paying after one month of running some Tor relays in the Amazon cloud:

per instance for one month (USD)

Remember that there is a “free usage” tier – this probably explains the $0 running cost charged for my Tokyo instance.

Conclusions from the above:

  1. Maximum bang for the buck if you can’t spend money on this: Run only one instance, preferably in a high-traffic area like South America. Expect to spend less than $10 per month.
  2. Expect to spend approximately $20/month/instance if you’re running more than one instances.
  3. I’ll kill all instances but Sao Paulo and Tokyo – at the moment all other instances seem to be receiving so little traffic they’re not worth the hassle.
