The Real Cost of Amazon CloudFront
If you do a little bit calculations for the real cost of the CDN, it turns out that it is much higher than the advertised pricing, for smaller files.
|File Size (KB)||Effective Cost per GB|
|5KB||$0.3797 (123% more)|
Here is how I calculated this - for US locations, data transfer rate (for first 10 TB / month) is $0.17 and request rate is $0.01 per 10,000 requests.
Effective cost per GB = $0.17+(1024*1024/file_size * 0.01/10000);
