1. Recommendation on the criteria and usage of data transfer fee
a. Camparison of transfer fee between importing S3 image using sdk in AWS and Url redirect output in apache
- In general, transfer fees are free of charge if they enter AWS, and if data inside are output, incur costs. For enquiries, redirecting apache is not a high cost, but when using sdk, it costs per the number of requests, and even if network traffic goes out internally in the same area too(for example, $8, for 100G). As the number of calls and the traffic cost occur at the same time, the cost is judged to be high. In case of out costs, they are all incurred.
b. Comparison of data transfer foo on S3 and EC2
- In 100G, the cost of data transfer out is network cost, resulting in $12.48 both EC2 and S3.
- Consider that if you have a lot of images, you can reduce costs by distinguishing between non-critical and important photos from S3 Storage Type.
Please note that cost will be change depending on request volume and other impacts.
