And probably many more that I can't think of at the moment...

I noticed many companies that do something similar offer a free trial for their services. How much money do you think they lose out this way? I assume they probably run an ec2 instance per customer, at least for the hosted graphite.

The cheapest ec2 instance is around $15/mo. If the trial is 30 days I’d assume they’re likely losing a lot of $15's here and there.

Am I wrong?
