I am trying to estimate how much I need to pay to store images for my customers on Amazon S3. I use their calculator but the total seems to cheap. Feels like I am missing something.
Each image is about 3 MB. Using the calculator I get a monthly sum of $21 if I got 60.000 images (180 GB). This seem very cheap indeed.
My servers are on Amazon EC2, do I still need to add transfer in and out to the calculator?
