So I've setup an Amazon AWS account for their Free Usage Tier offer.
2 days later I see this in my account info:
- data transfer in under the monthly global free tier: 0.023 GB
- regional data transfer + public / elastic IP data transfers: 0.023 GB
The numbers are OK, because I've been doing downloads to setup my instance.
But while the first item fits into the Free Usage Tier offer, the second does not, and right now my bill is 0.01 USD.
Why is that traffic counted twice? I am not doing any regional data transfers, so I guess they are billing me for traffic going through an Elastic IP.
How can I prevent that?
