Hi Cloudfront seems effectively to be one way of optimizing costs: see https://aws.amazon.com/blogs/networking-and-content-delivery/cost-optimizing-your-aws-architectures-by-utilizing-amazon-cloudfront-features/
On this topic, this article is interesting: https://www.stormit.cloud/blog/amazon-cloudfront-pricing-how-to-approach-it-and-save-money/
Best,

Using CloudFront reduces Data Transfer costs for 3 reasons:
- DTO of CloudFront is less than DTO of S3
- CloudFront Free Tier covers the first 1 TB per month
- Data transfers from S3 to CloudFront are free
For example, S3 DTO (in N.Amer) for the first 10 TB/month costs $0.09 per GB while CloudFront DTO for the First 10TB/month (in N.Amer) is $0.085 per GB. Both services have lower $/GB as volume increases but the rate of decrease is the same making CloudFront always the most cost-effective approach.
Also, the cost for each edge location varies. So, specifying price classes may further reduce DTO costs by excluding CloudFront edge locations that have a higher cost.
Hi Didier, Thanks for your answer. I have already gone through the DTO costs of both S3 and CloudFront and the DTO costs are almost the same. I don't see any huge difference in DTO pricing of the two btw different regions. In such case, how will cloudfront help cut costs as while people are downloading from CDN, still DTO is happening every download. Any help would be appreciated. Thanks
